SECTION I — GENERAL DESCRIPTION
1-1. GENERAL. YALE electric hoists are precision built wire rope and drum type hoists which are made in five rated load sizes (1/2, 1, 2, 3 and 5 tons) with various lifts, lifting speeds and electrical service. Equipped with an integrally welded mounting lug, they are designed to be rigidly attached to an overhead structure or mounted on YALE rigid mount trolleys for operation on runway beams. On certain models optional base mounting or other supporting methods may be obtained.
For full information apply to factory at Muskegon, Michigan
49443.
NOTICE
YALE hoists are available with an optional built-in mechanical overload clutch. Hoists having this device are identified with words WEIGHT WATCHER on the hoist.
The WEIGHT WATCHER overload clutch permits operation of your hoist within its rated load and helps prevent lifting of excessive loads which could cause permanent deformation of a properly maintained hoist or trolley.
1-2. BASIC CONSTRUCTION. All models are of the same basic construction and consist of a rugged welded steel frame which houses a lifting drum and serves as the suspension for carrying the entire hoist load. A mounting lug, for attaching the hoist to a trolley or overhead support, is located on top of the frame. An aluminum alloy gearcase and cover, attached to one end of frame, houses a three-reduction gear train and a mechanical load brake. An electric driving motor with disctype motor brake is located beside the frame, face mounted on the back of the gearcase. Electrical system components, located on the end of the frame (opposite gearcase end) and enclosed by a steel cover, control operation and rotating direction of a driving motor. A hoisting rope and an enclosed lower block assembly are used for lifting loads. An upper limit stop is used to limit travel of the lower block in the raising direction, to protect hoist from damage. A push button control station, for operating the hoist, is suspended from the electrical compartment.
1-3. DIFFERENCES BETWEEN MODELS. The main differences between models are in rope reeving and frame size as described below.
a. Rope Reeving. There are four types of rope reeving used:
Two parts of rope single reeved, four parts of rope single reeved, six parts of rope single reeved and two parts of rope double reeved. Single reeved hoists have one end of the rope anchored to the drum, whereas, double reeved hoists have both ends anchored to the drum. On single reeved models, the lower block travels sideways as rope winds on drum, double reeved models offer true ver tical lift. For illustrations, refer to Section V, paragraph 5-9, “Rope Reeving” instructions.
b. Frame Size. Length of frame furnished is dependent on hoist capacity and lift. Four frame lengths are used; short frame, long frame, first and second extensions. Short frame hoists have a rope drum flange to flange distance of approximately 9-3/4", whereas this distance on a long frame hoist is approximately 16-3/4". First extension frame hoists have a flange to flange distance of 22-15/16" and second extensions have 35-3/8".
c. Motor Brake. Hoists are equipped with a disc brake mounted on the motor end bell and operated by a short stroke solenoid.
This brake requires periodic adjustment.
SECTION II — INSTALLATION
2-1. GENERAL. YALE electric hoists are lubricated and tested before being shipped from the factory. To place hoist in service, attach to a suitable suspension (paragraph 2-2), connect to electrical service (paragraph 2-3) and perform pre-operation tests and checks (paragraph 2-4).
WARNING
Before attempting installation of hoist or trolley, the main power switch must be locked in the open position
(off).
2-2. SUSPENDING HOIST. The hoist may be suspended in a fixed location servicing only the area directly below the hoist
(Lug Mounted) or the hoist may be attached to a moveable trolley or trolleys which in turn may be mounted on an l-beam attached to a building or crane, servicing a larger area (Trolley
Mounted).
WARNING
DO NOT use small holes for attaching this hoist unless rated load on lower block is 1 (one) ton (2000 Ibs.) or less.
a. Lug Mounted hoists attach to adequate supports welded or bolted to a building or other structure. The supporting structure must have sufficient strength with appropriate safety factor, to support the weight of the hoist and rated load as well as other loads to which the supporting structure may be subjected.
WARNING
Design and installation of hoist support shall be performed only by qualified persons.
Steel angles or plates used to suspend hoist should be spaced as close to the hoist suspension lug as possible. Mounting bolts or threaded studs, attaching hoist to mounting structure, shall have a diameter not less than recommended by manufacturer and material equivalent to ASTM A 325. Make certain that mounting bolts or studs are long enough so that the threads do not engage the mounting support and that mounting bolts or studs are secured with nuts and lockwashers, self-locking nuts or cross bolting, if unthreaded.
b. Trolley Mounted hoists are attached to moveable trolleys. If the hoist is mounted on an existing trolley, a qualified person shall determine that the trolley and its supporting structure are adequate to support the rated load and weight of the hoist. Hoist/trolley units may be shipped from the factory with trolley packaged separately. If the trolley can be installed directly over the end of the supporting beam, assemble trolley to hoist. Be certain that the spacing between wheel flanges, after assembly, is 1/4" greater than exact width of beam flange. (See Figure 2-1 below and instruction sheet furnished with trolley.) Using proper equipment, carefully lift trolley and hoist and install on end of beam.
Page 3
For trolleys which are to be mounted along the span of a beam not having open ends, measure exact width of beam flange and assemble trolley to hoist so that spacing between wheel flanges is 1/4" (see Figure 2-1) greater than beam width (3/8" if beam has curves). This is accomplished by rearranging the spacer washers on the bolts connecting trolley side plates to hoist mounting lug. If trolley is shipped separate from hoist, see instruction sheets furnished with trolley for orientation and installation.
When proper spacing has been determined, loosen mounting nuts (item 1, Figure 2-1) to allow trolley wheels to spread far enough to pass over edges of beam flange. (Some installations may require complete removal of one trolley side plate.) Using adequate equipment, carefully lift the hoist and trolley so the wheel treads will rest on the lower beam flange. Replace side plate and washers if removed for installation. Replace suspension stud nuts.
CAUTION
Recheck spacer washers to make certain that the number of washers between the side plate and hoist suspension lug are equal, and also the number on the outside of each side plate are equal. The suspension stud nuts should only be snugged up on the lockwashers until a load has been applied on the hook. A partial load (approx. 25% rated hoist load) placed on the hook will properly seat hoist in the trolley. Tighten suspension stud nuts only after hoist has been properly seated in the trolley.
WARNING
Be certain that electrical power supply is off and locked in the open position before attempting any electrical connections to the hoist. This equipment must be effectively grounded according to the National Electric
Code, or other applicable codes. If the grounding method used is through the trolley wheels, then each section of track must be grounded by metal-to-metal connection to the building ground. Cer tain environments may prevent proper grounding by this means. In this case a separate grounding conductor should be provided.
a. Follow National, State and Local Electrical Codes when providing electrical service to the hoist.
CAUTION
208/230/460V single speed motors are reconnectable at the motor. See motor nameplate. Transformer may be reconnected for 200/230/460/575V. See transformer. Check with wiring diagram to make certain that motor, transformer and brake leads are properly connected.
b. Make electrical connections using the appropriate wiring diagrams furnished with the hoist. All electrical connections, including connections to collectors or power cord, shall be made only by qualified journeymen electricians.
WARNING
Mounting of the hoist-trolley unit on the monorail and final pre-operation inspection shall be performed only by qualified persons properly supervised.
11207A
Figure 2-1. Sectional View of Trolley showing proper wheel and washer spacing.
2-3. CONNECTING HOIST TO ELECTRICAL SERVICE.
Electrical service to the hoist may be power cable or a guarded system having sliding shoe collectors.
WARNING
The green wire provided in the power supply cable
(when furnished) is a grounding wire and must be connected to a proper ground.
c. When trolley is shipped separate from hoist, see special instructions fur nished with trolley for or ientation and installation.
2-4. PRE-OPERATION CHECKS.
a. Check Oil Level and Grease Fittings. The gearcase has been filled with oil to the proper level and grease points for lower and upper sheaves have been lubricated at the factory.
However, this should be checked before operating hoist. Check oil level by removing oil level plug with hoist in a level position.
Oil level should be at the bottom edge of the plug hole. If not, add oil as specified in Section IV. Grease fittings in lower and upper sheave pins should show evidence of grease.
CAUTION
Overfilling of the gearcase may result in the excess fluid being expelled through the breather.
Page 4
b. Check Push Button Operation and Phasing.
WARNING
On three phase hoists it is possible to have “Reverse
Phasing” causing the lower block to lower when the
á button is depressed. When this condition exists, the automatic limit stop switch is inoperative and hoist operation will be dangerous.
To properly check the phase of the hoist, follow the steps below:
(1) With “POWER OFF” operate all the push buttons and determine that they do not bind or stick in any position
When floating rod is raised, stop switch is actuated first and then the reversing switch is actuated (Figure 2-3). Stop switch stops hoist. Reversing switch lowers hook block in case of floating rod over-travel. If limit switch does not function in this manner, refer to trouble shooting chart Section Vl for possible remedy.
WARNING
If any push button binds or sticks in any position —
DO NOT TURN POWER ON — determine the cause and correct the malfunction before operating.
(2) Temporarily connect hoist to power source.
(3) Operate á button briefly to determine direction of hook travel.
(4) If hook raises, phase is correct. Turn power off and make temporary connections permanent.
(5) If hook lowers, hoist is “Reverse Phased”. TURN
POWER OFF and correct by interchanging any two leads at power source connection. Do not change internal wiring of hoist.
c. Check Limit Switch Operation.
(1) A block operated upper limit stop (Figure 2-2) is furnished as standard equipment. This limit stop is factory set to stop lower block in its high position and guard against over-travel and possible damage to hoist. (Note mounting position of floating lever for 3 and 5 ton hoists.) No adjustment can be made. Limit switch operation should be tested when hoist is installed. Move hook to a low position by depressing push button marked â. Now depress button marked á to raise hook. While hook is traveling upward, manually (or with an extension pole) raise limit stop mechanism (Figure 2-2).
Figure 2-3. Electrical Compartment Cover Removed
Showing Limit Switch and Reversing Switch Arrangement.
WARNING
Do not attempt to make above test with hook in a high position near hoist.
(2) A screw-type upper and lower limit switch is provided optionally when both upper and lower limit stops are required
(Figure 7-2). This switch is adjustable and must be adjusted, at time hoist is installed, to desired high and low limits of lower block travel. Refer to Section Vll.
d. Check Lower Block and Hoisting Cable. Depress â push button and run lower block to its lowest position. No less than two wraps shall remain on the drum with the loaded hook in its lowest position, unless hoist is equipped with a lower limit switch in which case no less than one and one half wraps shall remain on the drum. Also check to see that lower block and rope does not twist excessively. If it does twist to the extent that two ropes rub against each other, disengage rope from the frame anchor and twist rope four or five turns in a direction opposite to that which the block turns. Reconnect rope to anchor (Figure 2-4), holding firmly to eliminate rope twisting back to its original position. Operate hoist up and down a few times. If lower block still rotates, repeat process until twisting is corrected.
e. Lubricate Hoisting Cable. For longer cable life, it is recommended that the cable be lubricated at time of installation by applying a Chain and Cable Fluid as outlined in Section IV, paragraph 4-3.

SECTION III — OPERATION
3-1. GENERAL. Operation of Series 800 YALE electric hoists is controlled by a convenient pendant push button station.
With it, the hoist can be controlled to give fast lifting and lowering; or controlled to lift or lower load in small increments, providing accurate spotting. The push button station has a built-in interlock to prevent depressing opposing buttons simultaneously.
When first using hoist, break-in by operating under lighter loads to full travel before applying maximum load.
3-2. PUSH BUTTON OPERATION.
a. Depress push button marked á to raise load.
b. Depress push button marked â to lower load.
c. Jogging the push button will give “hairline” load movement.
The quickness of the depressing motion will determine the amount of movement. Excessive use of this “Jogging” feature will cause premature burning of contact tips and motor overheating.
d. On two-speed hoists, partial depression of button operates the hoist at slow speed; depressing button completely operates the hoist at fast speed.
3-3.
OVERLOAD CLUTCH OPERATION (Optional). The overload clutch, when furnished with the hoist, is factory preset and tested so that the hoist will lift its full rated load but will refuse to lift overloads which could cause deformation or weakening of your hoist. If the load to be lifted exceeds the clutch setting, the hoist motor will continue to run when the á button is depressed and rotate the load brake gear without lifting the load. Whenever this slipping occurs, immediately release the á push button to prevent overheating of the clutch friction surfaces and the hoist motor.
NOTICE
Always know load to be lifted. Lift-Tech does not recommend lifting loads greater than the rated load of your hoist.
3-4.
OPERATING PRECAUTIONS.
WARNING
Equipment covered herein is not designed or suitable as a power source for lifting or lowering persons.
Safe operation of an overhead hoist is the operator’s responsibility. Listed below are some basic rules that can make an operator aware of dangerous practices to avoid and precautions to take for his own safety and the safety of others.
Observance of these rules in addition to frequent examinations and periodic inspection of the equipment may save injury to personnel and damage to equipment.
a.

s.
DO NOT lift more than rated load.
t.
DO NOT use a damaged hoist or a hoist that is not working correctly.
u.
DO NOT use the hoist with twisted, kinked, damaged or worn wire rope.
v.
DO NOT lift a load unless wire rope is properly seated in its drum groove(s).
w.
DO NOT use wire rope as a sling or wrap rope around the load.
x.
DO NOT lift a load if any binding prevents equal loading on all supporting ropes.
y.
DO NOT apply the load to the tip of the hook.
z.
DO NOT operate unless load is centered under hoist.
aa. DO NOT allow your attention to be diverted from operating the hoist.
ab. DO NOT operate the hoist beyond limits of wire rope travel.
ac. DO NOT use limit switches as routine operating stops unless recommended. They are emergency devices only.
ad. DO NOT use hoist to lift, support or transport people.

WARNING
DO NOT operate hoist with the hoisting rope out of the drum groves. Such operation may result in the rope breaking and dropping the load which can cause damage to equipment and injury to operator and other personnel. Hoist rope will remain in the drum groves during operation under normal operating conditions, however, slack or kinked rope, excessive side pulls, swinging or jerking of load, or similar abuse, may cause the rope to leave the groves.
SECTION IV — LUBRICATION
4-1. GENERAL. T h e l u b r i c a t i o n s e r v i c e s o u t l i n e d i n paragraphs 4-2 thru 4-6 should be performed at regular intervals to maintain top hoist performance and ensure long life. Intervals of at least six (6) months, coinciding with spring and fall seasons, are recommended. The reason for this is, on hoists installed out-of-doors and in unheated areas, a
“cold test” lubricant is required in cold (below freezing) climates making seasonal changes necessary.
4-2. CHANGE GEARCASE OIL. (Figure 4-1) a.
Remove oil drain plug from bottom of gearcase and drain out oil. (Two drain plugs, one on front and one on back of gearcase.) b.
Flush out housing using petroleum solvent. Reinstall drain plug.
c.
Refill thru oil hole cover to proper level (bottom of oil level plug hole) using 10 pints of Automatic Transmission
Fluid, DEXRON III Type, suitable for all temperature ranges.
aq. DO operate hoist within recommended duty cycle and do not “jog’’ unnecessarily.
ar.
DO conduct regular visual inspections for signs of damage or wear.
as. DO NOT operate hoist with hooks that have opened up. See Figure 5-1.
at.
DO provide supporting structure or anchoring means that has a load rating at least equal to that of the hoist.
au. DO NOT use hoists in locations that will not allow operator movement to be free of the load.
av. DO, when starting to lift or pull, move the load a few inches at which time the hoist should be checked for proper load holding action. The operation shall be continued only after the operator is assured that the hoist is operating properly.
aw. DO NOT leave a loaded hoist unattended at the end of a work shift or for extended periods during the work shift. Where operations are such that this condition cannot be avoided the operator must be assured that the condition does not create a hazard to personnel or property.
ax. DO NOT use the hoist load limiting device to measure the load.
ay. DO NOT operate hoist unless hook moves in the same direction as indicated on the pushbutton. If opposite direction occurs, see pre-operation checks, Paragraph 2-
4.b.
az. Observe recommended inspection and maintenance procedures.
ba. DO use common sense and best judgement whenever operating a hoist. Observe American National Standard
Safety standard, ANSI B30.16, Iatest issue.

SECTION V
INSPECTION AND PREVENTIVE
MAINTENANCE
5-1.
GENERAL. YALE, Series 800, hoists are inspected and tested at the factory. Regular in service inspection and preventive maintenance programs not only help reduce overall maintenance costs but may also prevent serious shutdowns by forewarning of problems that could cause these shutdowns.
Regular inspections, periodic minor adjustments, regular cleaning and lubrication and replacement of worn parts can help preserve good performance and operation of your hoist.
Many factors influence the inspection and preventive maintenance program required for your hoist. Frequency and severity of service and material handled, local environmental conditions and various applicable codes are some of the factors that the user must consider to adjust inspection and maintenance program outlined in this section to meet his specific conditions.
The inspection and maintenance services outlined in this section are considered minimum. Recommended in the schedule are minimum inspection and maintenance intervals based on average daily use in a normal environment. Average daily use is based on 1000 operational hours per year maximum and intermittent operation of the hoist eight hours per day, five days per week with a maximum 40% “on” time and the average loading not exceeding 65% of rated load.
Environmental conditions in which the hoist operates are also important considerations for the user when adjusting hoist inspection and maintenance programs to local conditions.
Frequency of inspection and maintenance must be increased if hoist is subjected to severe atmospheric environmental conditions, such as corrosive vapors, extreme heat or cold, cement or dust and other airborne contaminants. The user should carefully consider all environmental conditions and adjust frequency and degree of maintenance for his local conditions. Consult Lift-Tech Field Service Department for advice for unusual environmental conditions.
Various codes also regulate inspection and maintenance programs. Attention must be given to applicable Federal
Standards, OSHA regulations, National Standards, state and local codes which may include mandatory rules relating to hoist inspection and maintenance. The user should become familiar with all applicable codes for his area and be guided accordingly.
Listed on the Recommended Inspection and Maintenance
Schedule are inspection frequencies and requirements.
Perfor m these inspections regularly as scheduled and additional inspections as may be required for activity, service and environment of your hoist. The hoist operator must be responsible for determining the operating conditions and severity of service.
Inspection Schedule and Maintenance Report Form.
Shown on page 10 of this manual is a recommended
Inspection Schedule and Maintenance Report form which lists various components of the hoist. The form also includes trolley components, runway components, and miscellaneous items. This form is suggested as a guide for written inspection
Page 8 reports. Inspections are recommended each month and should be performed thoroughly enough to inform the hoist user of deficiencies for any item listed. This form does not supersede the Inspection and Maintenance Schedule listed below but may be used to record scheduled inspection and maintenance services required.
The user should revise the inspection interval, add additional units or provide a similar form to suit particular conditions which may exist. However, written, dated and signed inspection reports should be maintained particularly on critical items, such as hoist hooks, hoisting ropes, sheaves, drums and brakes. Periodic review of old inspection reports can point out service life of hoist components, forecasting need for adjustment, repair or replacement of these components.
As a matter of expedience, appointed maintenance personnel inspecting the hoist can also take care of minor adjustments, repairs and cleaning, where required. Note the column on
Inspection Schedule and Maintenance Report form headed
Corrective Action and Notes. When corrective action is made during inspection, note condition of part or unit as inspected in appropriate Condition column with a check mark (
ü
). Note
“during inspection” corrective action taken and date in space provided. In this manner, items requiring further attention will be checked (
ü
) without showing corrective action. This will advise the designated person responsible for hoist operation and safety, who reviews the reports, that deficiencies exist.
The designated person will check all deficiencies as listed and reexamine or otherwise determine whether they constitute a safety
WARNING
Deficiencies may be hazardous to personnel and equipment. Do not operate a hoist having deficiencies unless a designated qualified person has determined that these deficiencies DO NOT constitute a safety hazard.
Written, dated and signed inspection reports for many items are mandatory under OSHA regulations, and many state safety codes. It is strongly recommended that the Inspection
Schedule and Maintenance Repor t, shown herein, be completed by a qualified person designated with the responsibility for hoist operation and safety or an inspector appointed by this person.
Inspection records can point out the service life of hoist components and help forecast the need for adjustments, repairs and ordering of replacement parts. File and review these reports after each inspection.
WARNING
Do not operate a hoist having unusual vibrations, sounds or other conditions. Danger may be present that the hoist operator cannot see. Determine and correct cause of unusual conditions and make certain the hoist can be operated safely. Be certain to disconnect power to the hoist whenever electrical cover is removed.
5-2. INSPECT LOWER BLOCK.
a.
Check lubrication of all parts. If the thrust bearing is not equipped with a grease fitting, lubricate with SAE No. 50 oil.
Also lubricate the shank of the hook which passes through the lower block body.
b.
Check each sheave to ensure rope groove is smooth and free from burrs, or other surface defects.
c.
Check each sheave for freedom of rotation; replace bearings if defective.
d.
Make certain that dowel pin, holding the hook nut to the hook, is securely in position.
e.
If hook is equipped with a safety latch or rotational lock, check to determine that they are in good operating condition.
f.
Check throat opening of hook. (Refer to Figure 5-1.) It is recommended that upon receipt of the hoist a measurement be made and recorded of the hook throat opening. OSHA
Standards require that the hook be replaced if the throat opening exceeds 15 percent of the original opening, or if the hook is twisted more than 10 degrees from the unbent plane.
A gage block, properly identified to the hoist, similar to the one shown in Figure 5-1, is suggested to be made for each hook for use in these measurements.
NOTE: Hooks and hook openings shown are based on hooks normally furnished with standard hoists. For dimensions of hooks having a special size, shape or material, consult the Muskegon, Michigan factory. For hooks with certain kinds of safety latches it may be necessary to remove latch to measure hook opening.
g.
Hooks showing signs of cracks must be replaced. Hooks should be inspected at least once per year using dye penetrants, magnetic particle or other suitable crack detecting methods.
c.
Make certain that rope guide pins are not bent, loose or otherwise distorted; guide pins must have close clearance to sheave flange to keep rope in sheave grooves.
d.
Check hoist suspension bolts on lug suspended hoists; make certain that bolts are secure, properly tightened and free from damage.
e.
Inspect suspension lug at top of hoist frame for damage, cracks, hole elongation or other signs of wear. On all hoists, the suspension lug is integral with hoist frame and the entire frame must be replaced when suspension lug is damaged and requires replacement.
WARNING
Do not operate a hoist having worn or damages suspension bolts.
f.
Reinstall all parts following procedure in reverse of disassembly.
5-4. INSPECT ELECTRICAL CONTROLS. Arrangement of electrical control equipment varies with the type of control, physical space and the optional control features ordered with the hoist.
a.
Disconnect electrical power to hoist, remove electrical compartment cover (Figure 9-1, Ref. No. 29) and inspect wiring and terminals. Terminals should be securely crimped to wires and electrical insulation should be sound. Terminal screws should be tight.
b.
Check condition of contactor assembly, transformer, and limit stop and reverse switches.

g.
Reassemble gearing and load brake par ts following reverse procedure of disassembly. In assembling load brake, observe assembly steps (1) through (4) below:
(1) Before installing spring in its retainer (Figure 5-9), apply a good grade of ball bearing grease to inside of retainer.
Spring must be positioned exactly as illustrated, butted against pin at side of cam.
LOAD BRAKE — OVERLOAD CLUTCH
LOAD BRAKE — STANDARD
Figure 5-9. Load Brake Gear Removed From
Load Brake Showing Load Brake Spring.
(2) When installing pawl and ratchet assembly on load brake shaft, be certain that teeth on ratchet face are in the same direction as shown in Figure 5-8. The ratchet assembly should rotate freely when turned counterclockwise and the pawl should engage ratchet teeth when unit is turned clockwise.
(3) When installing brake flange, position it with chamfer facing friction disc (Figure 5-7).
(4) The brake spring must be pre-loaded at assembly to a torque of from 10 to 14 lb.-ft. This is accomplished using a plumber’s strap wrench to wind (rotate) load brake gear to set up spring (Figure 5-10) while pressing brake flange into place using an arbor press. Clamp pinion end of shaft into a portable vise to keep brake from rotating in press. Use brass or copper jaw plates on vise to protect pinion gear teeth.
Wind gear counterclockwise (viewing brake from flange end) with strap wrench and press down on flange until snap ring groove in shaft is exposed allowing snap ring to be installed.
Use extreme care not to over wind spring as yield will result and final spring torque will be reduced. Do not wind gear beyond point necessary to install snap ring in groove.
h. Install gearing and load brake assembly in gearcase in reverse order of disassembly. Be certain roller thrust bearings are installed at both ends of intermediate gear shaft as shown in Figure 5-4 and that thrust washers are properly installed at both ends of load brake shaft as noted below:
(1) A steel thrust washer with 5/8" I.D. must be installed on the brake flange end (end opposite pinion) of load brake as shown in Figure 5-5.
(2) A bronze thrust washer with a lug on one side goes on pinion end of load brake shaft and it must be installed so that its lug engages the special slot located on the spot face surrounding the load brake bearing bore inside gearcase cover. Use heavy grease to hold it in place on cover as cover is installed.
On hoists with 18 or 20 tooth load brake pinion, an 11/
16" I.D. steel thrust washer is installed between pinion and bronze thrust washer.
j.
At completion of reassembly of gearing and load brake in gearcase, refill gearcase to proper level using correct grade of oil, as outlined in Section IV — LUBRICATION.
k. For hoists equipped with an overload clutch (optional) which has been functioning properly, visually inspect clutch adjusting nut and spring washer for signs of damage or looseness. With a small hex allen wrench, make certain two set screws in adjusting nut are tight. DO NOT TURN
ADJUSTING NUT OR DISASSEMBLE CLUTCH. If spring washer, adjusting nut or gear is loose or damaged, or the clutch did not function properly before disassembly of hoist for inspection, consult the nearest YALE Authorized Repair
Station for repair or adjustment.
5-7.
INSPECT ROPE DRUM AND SHAFT.
a.
To r e m ove d r u m , r e m ove w i r e r o p e, e l e c t r i c a l compartment cover and electrical panel assembly (Figure
9-1) and gearing and load brake assembly (paragraph 5-6).
b.
Remove four hex socket head bolts securing gearcase to cover. Three bolts are accessible from inside frame (Figure
2-2, Section II) and the fourth is accessible from electrical end of frame thru special access hole using a socket hex key wrench with an extension (Figure 5-11). With bolts removed, pry assembled gearcase and motor from frame. Exercise caution so that gearcase and motor assembly does not fall as it comes free of frame. This disassembly operation is not recommended with hoist suspended. Drum will remain in frame and can be lifted from drum shaft. To remove shaft, remove internal retaining ring from bearing bore in frame.

b.
Maintenance. Keep rope well lubricated to help reduce internal friction and prevent corrosion. Lubricant, as described in paragraph 4-3, should be applied as a part of the regular maintenance program. Special attention is required to lubricate sections of rope over equalizing sheaves and other hidden areas.
Avoid dragging ropes in dirt or around sharp objects which will scrape, nick, crush or induce sharp bends in the rope.
c.
Replacement. When recommended by an authorized inspector, the rope should be replaced. Replacement rope assemblies are shipped from the factory carefully coiled to prevent damage by kinking. Care must be taken to avoid twisting or kinking when uncoiling and handling during reeving.
Before replacing rope, check condition of grooves in sheaves and drums to determine if they are excessively worn.

REPLACEMENT.
WARNING
Use only factory approved rope with swagged wire rope sockets.
WARNING
Wire rope improperly handled or abused can create a
SAFETY HAZARD. Read and comply with inspection, maintenance and replacement information given herein.
a.
Inspection. Wire rope on your hoist is one of the most impor tant components requiring frequent inspection and maintenance. All wire ropes will eventually deteriorate to a point where they are not safe and will require replacement.
WIRE ROPE SHOULD BE THOROUGHLY INSPECTED AT
REGULAR MONTHLY INTERVALS BY AN AUTHORIZED
PERSON AND A DETERMINATION MADE WHEN FURTHER
USE OF THE ROPE WOULD CONSTITUTE A SAFETY
HAZARD. Each inspection should include a written, dated and signed report of rope condition. Reports should be filed and reviewed each month and any rope deterioration carefully noted. Inspections revealing but not limited to the following conditions should cause the inspector to question remaining strength of rope and consider replacement:
(1) Twelve randomly distributed broken wires in one rope lay or four broken wires in one strand.
(2) Wear of one-third of the original diameter of outside individual wires.
(3) Kinking, crushing or bird caging.
(4) Heat damage from any cause.
(5) Reductions from nominal diameter of more than
1/64" for 3/16", 1/4", and 5/16" diameter rope.
(6) Rope corrosion, internal or external.
(7) Effects from improper lubrication.
(8) Rope idle for month or more due to shutdown.
Special attention should be exercised when inspecting rope normally hidden during inspecting procedures.
When first using the hoist after rope replacement, break-in rope by operating under lighter loads to full travel before applying maximum load.
5-9. ROPE REEVING.
a.
General. Before unreeling rope from a coil or reel, be sure floor is clean. Dirt picked up by the rope can cause excessive wear and abrasion. Uncoil the rope by rolling the coil or reel along the floor; or, place reel on a stand with a shaft thru the center of reel so rope can be pulled straight out with the reel rotating.
CAUTION
It is imperative that the rope reel or coil rotates as rope unwinds. If coil or reel does not rotate, the wire will be twisted as it is uncoiled and kinking will result. A kinked rope may be damaged and unsafe.
Before removing the old rope, refer to reeving diagrams,
(Figures 5-12, 5-14, 5-15 and 5-17). Face the rope drum on your hoist from the side which the rope comes off drum. To assist with rereeving your hoist, select the reeving diagram for your hoist. Note the description (such as 2 part double reeved, Figure 5-17) and refer to the paragraph below with the same description which describes rereeving procedure.
b.
Removing old rope — for all reevings.
(1) Lower the bottom block to a scaffold located 6 to 7 feet below hoist to relieve tension on wire rope. (Bottom block may be lowered to floor if desired; however, to handle less weight and for ease of rereeving adequate scaffold below the hoist is recommended.)
(2) Remove bottom block sheave guard.
(3) Remove key plates from both sides of sheave pin and slide sheave pin from bottom block.
(4) Lift out sheaves from the top of the bottom block and remove wire rope.
Page 14
(5) Remove key plates or snap rings from upper block sheave(s) and slide out upper block sheave pins, releasing upper block sheaves. Remove wire rope from sheaves.
(6) Make certain all personnel are clear of hoist and operate hoist
â
to completely unwind all wire rope from drum. Stop hoist so drum anchor slot(s) is accessible. Remove live rope and socket(s) from drum.
(7) TURN OFF POWER TO HOIST.
(8) Remove the bolt and lockwasher in the end of the rope anchor fitting. Remove rope from slot in top of anchor.
c. Installing new rope.
WARNING
Winding rope on rope drums with power can be hazardous. Keep hands safe distance from drum, wear gloves and use extreme care when handling rope.
With new rope installed on the drum as described in paragraph
5-9c single reeved above, proceed with rereeving following steps below:
(1) Pass other end of rope thru bottom opening of hoist, between floating limit rod and motor, and attach rope to cast dead end anchor fitting. A slot is located at top of fitting to accept cable. Reinstall bolt and lockwasher in end of anchor fitting to lock rope compression fitting in place.
(2) Grasp loop, formed after installing end anchor, and place bottom block sheave in loop. Lower sheave into bottom block and insert sheave pin. Replace key plates and bolts holding sheave pin in place.
(3) Replace sheave guard. Make certain rope is not twisted. Should the two parts of rope tend to wind around each other, remove cable from anchor slot and untwist cable.
Reattach the cable anchor.
(4) Lubricate cable per paragraph 4-3.

(5) Replace sheave guard.
(6) Lubricate rope per paragraph 4-3.
h. Checking for and removal of rope twisting.
Although rereeving of hoist may have been done carefully, sometimes after new rope has been installed twisting may occur. With new rope installed, the hoist block should be raised and lowered several times with gradually increasing loads, through full lift. If the block still rotates excessively at no load, the rope may have twists which should be removed.
(1) To remove rope twist in single reeved hoists.
(a) Observe direction block tends to rotate.
(b) Lower the block to a low position and turn off power.
(c) Rotate rope near the anchor end several turns in a direction tending to correct block rotation. This rotates rope end fitting in the anchor.
(d) Tur n on power ; raise and lower the block several times to feed the correcting twist in the rope through the reeving.
(e) If block still tends to twist, repeat the above procedure until block rotation is corrected.
(2) To remove rope twist in double reeved hoists.
(a) Observe direction block tends to rotate.
(b) Lower the bottom block unspooling rope from rope drum until only one quarter (1/4) turn remains to rope end anchors in drum.
(c) Rotate rope near ends entering drum in a direction tending to correct block rotation. This rotates rope end fittings in the drum.
(d) Turn on power; raise and lower the block several times to feed the correcting twist in the rope through the reeving.
(e) If block still tends to twist, repeat the above procedure until block rotation is corrected.
5-10. T E S T I N G H O I S T A N D OV E R L OA D C L U T C H
(Optional).
a.
General. Before placing hoist in service or after disassembly and reassembly, hoist should be tested. To test suspend hoist from an overhead supporting member of sufficient strength to support the weight of the hoist and the rated load.
Hoists having overload clutches, require an overhead supporting structure capable of supporting with appropriate safety factor, a load equal to 200 percent rated load and the weight of the hoist. Connect hoist to power supply as shown on hoist nameplate and perform the checks listed in b and c below.
b.
Check hoist as outlined in PRE-OPERATION CHECKS,
Section II, paragraph 2-4.
c.
Check hoist with capacity load.
(1) Attach rated load to lower hook.
(2) Depress á push button and raise load. When push button is released, hoist should immediately stop and hold load at that level.
(3) Depress â push button, lower load a short distance and release button. Hoist should stop immediately and hold load at that level.
NOTE: If load drifts downward slowly in step 2 or
3 above, motor brake requires adjustment — see
MOTOR BRAKE ADJUSTMENT — Section Vll — paragraph 7-2.
d.
Overload Clutch. The overload clutch (optional) must be tested for proper operation before placing hoist in service or after disassembly and reassembly of hoist. For test procedure follow instructions listed below.
Page 17
WARNING
BEFORE ATTEMPTING TO TEST THE OVERLOAD
CLUTCH, MAKE CERTAIN THE FOLLOWING
PREREQUISITES ARE STRICTLY OBSERVED: a.
An appointed person must determine, before starting, that all structures supporting the hoist are adequately strong to withstand the test load of 200% of the rated load, plus the weight of the hoist, whether hoist is tested in installed position or moved to a designated test facility.
b. Loads used for testing must be accurately known.
c.
Test must be made ONLY by a qualified operator, thoroughly familiar with the hoist and the purpose of the test.
d. Adequate and proper rigging must be provided to ensure that test loads are securely attached, properly balanced, and lifted level. Failure to provide adequate support could cause injury to personnel and/or damage to equipment.
(1) Using a known load, equal to the hoist rated load, energize hoist to lift the load. Raise this load just high enough to be certain hoist is lifting the entire load. Clutch should not
slip with the rated load. Lower load to rest position. If clutch slips with rated load, adjustment is required. (See paragraph
7-5. — “OVERLOAD CLUTCH ADJUSTMENT”.) If hoist will lift rated load, proceed to step (2).
(2) Increase load in steps from rated load, TO A MAXIMUM
OF 200% of the rated load, attempting to lift load with each increase in weight. Hoist Overload Clutch should slip and refuse to lift load before 200% of the rated load is reached. Should hoist lift 200% of the rated load — STOP TEST — A CLUTCH
ADJUSTMENT IS REQUIRED. (See paragraph 7-5 —
“OVERLOAD CLUTCH ADJUSTMENT”.)
(3) Run hoist with load causing clutch to slip (hoist refusing load) five cycles of approximately 1 second each.
CAUTION
To prevent overheating, release the hoist control button at once when the hoist refuses to lift the load.
(4) Remove weights added in step (2) and return to hoist rated load. Lift rated load one final time. Clutch should not slip.
WARNING
Do not lift more than rated load except for test purposes.
NOTICE
ALWAYS KNOW LOAD TO BE LIFTED, LIFT-TECH
DOES NOT RECOMMEND LIFTING LOADS GREATER
THAN THE RATED LOAD OF YOUR HOIST.

Trouble
6-5. Hoist Will Not Lift Rated
Load.
SECTION Vl - TROUBLE SHOOTING (Continued)
Probable Cause Remedy
a. Low voltage a. See that power supply current is same voltage
Iisted on motor data plate. Check hoist motor connections. Check size of power supply lines.
b. Overload Clutch not properly adjusted.
b. See Section VII, paragraph 7-5.
6-6. Hoist Motor Overheats.
a. Excessive load.
a. Reduce loading to rated load of hoist, shown on nameplate.
b. Excessive duty-cycle.
b. Reduce frequency of lifts or amount of jogging.
c. Wrong voltage or frequency.
c. Check current rating on motor data plate against power supply. Check hoist motor connections.
d. Defective motor or worn bearings in hoist frame.
d. Disassemble hoist and inspect for defective, worn or damaged parts.
e. Overload Clutch slipping without lifting load.
e. See Section VII, paragraph 7-5.
6-7. Load Drifts Excessively
When Hoist Is Stopped.
6-8. Hoist Operates
Intermittently a. Excessive load.
b. Motor brake not holding.
c. Load brake not holding.
a. Reduce loading to rated load, as shown on nameplate.
b. With No Load, check hoist for drift. If drifting is excessive, inspect motor brake (Section V, paragraph 5-5) and adjust as outlined in Section
VII, paragraph 7-2.
c. (1) After determining that the motor brake is working properly, attach rated load to hook and operate hoist. If the load accelerates during lowering, the load brake is not functioning properly. See Section
V, paragraph 5-6 for replacing worn or damaged parts.
(2) If load brake checks O.K., magnetic motor brake needs adjustment (see b. above).
a. Collectors make poor contact.
b. Loose connections.
a. Check collectors for free movement of spring arm, weak spring or electrical connections.
b. Check all wiring for loose connections.

SECTION Vll — ADJUSTMENTS
7-1.
MECHANICAL LOAD BRAKE. The mechanical load brake on Series 800 YALE hoists is a pawl and ratchet “Weston” type automatic brake. The brake is not adjustable and requires only periodic inspection and occasional replacement of the friction washers.
7-2.
MOTOR BRAKE. Instructions for adjusting the brake are inside the brake cover and are repeated below. Check brake adjustment after the first 30 days of service and regularly thereafter during the six-month inspection procedure. Two versions of the motor brake occur in this manual.
12759C
Figure 7-1A. Motor Brake - Later Version.
c.
On the early version of the brake (Figure 7-1), if the tang is below the midway position of the two adjustment points shown on the brake, the brake should be adjusted to bring the tang back up alongside the NORMAL position on the brake.
d.
Remove the hex key (1/8" size) from the holster on the cover mounting stud and carefully turn the ADJUSTING SCREW
(located above the solenoid coil) clockwise. The indicating tang will move a large distance for a small turn of the adjusting screw, therefore turn the screw no more than one quarter turn before checking adjustment.
e.
After adjustment operate the brake by hand to assure brake disc running clearance. The outboard brake pad should separate from the brake disc by approximately .010".
f.
Replace hex key in holster.
g Replace brake cover.
7-3.
BLOCK OPERATED LIMIT SWITCH. The block operated upper limit stop, fur nished as standard equipment, is nonadjustable and designed to stop lower block at its high point of travel to guard against over-travel with possible damage to hoist. When high point is reached, limit stop switch automatically stops hook travel. If hook drifts upward slightly after stop switch is actuated, a reversing switch will close and automatically reverse direction of hook travel.
7-4.
SCREW-TYPE LIMIT SWITCH. This limit switch has a rotary screw driven by a gear reduction which is coupled to the end of the drum shaft. Adjustment discs operate the contacts of separate switches; one for the hoisting circuit and one for the lowering circuit. The switch assembly must be wired in accordance with the appropriate wiring diagram, which is packaged with hoist. Adjustment of this screw-type limit switch is accomplished as follows: (Refer to Figure 7-2).
WARNING
Before attempting actual adjustments, be certain main power switch is OFF and locked in the open position.
12759
Figure 7-1. Motor Brake - Early Version.
a.
Examine position of indicating tang located below the solenoid coil (Figure 7-1 or 7-1A).
b.
On the later version of the brake (Figure 7-1A), if the tang is below the line by more than 1/8", the brake should be adjusted to bring the top of the tang back up alongside the line on the adjust label.

Slide locking plate back into position ensuring slots on adjustment discs are fully engaged, tighten locking plate screws to 4 in-lbs.
e.
Replace cover.
hoist is furnished as a separate insert and shipped with hoist.
We suggest you carefully file the wiring diagram with this book for future reference.
WHEN ORDERING PARTS OR INFORMATION ON THIS
EQUIPMENT, ALWAYS INCLUDE MODEL AND SERIAL
NUMBER ON ORDER.
WARNING
Check limit switch operation carefully, without load, before placing hoist in service. If misadjusted, SEVERE
DAMAGE AND/OR A DROPPED LOAD COULD RESULT.
Allow 6" for hook drift in both directions. Never allow less than 1-1/2 complete wraps of rope on drum with hook in lowest position.
Provide a light film of NLGI No. 2 grease on bevel gear of limit switch.
7-5.
OVERLOAD CLUTCH ADJUSTMENT. When properly adjusted, the overload device is designed so that the hoist will lift its full rated load but will refuse to lift an excessive overload.
The overload clutch is not externally adjustable. It is necessary to remove the overload clutch assembly from the hoist for proper adjustment. Therefore, it is strongly recommended that when adjustment and/or replacement parts are required, a SHAWBOX
Authorized Repair Station be contacted. Consult your SHAWBOX
Distributor for nearest Repair Station.
SECTION VIII — WIRING DIAGRAMS
Wiring diagrams for SHAWBOX electric hoists have been omitted from this book because of many possible variations. This is due to different currents and types of electrical components used in their construction. A print of the correct wiring diagram for each
SECTION IX — PARTS LIST
9-1.
GENERAL. The parts lists and illustrations in this section of the manual, cover parts for all standard 800 SHAWBOX
Electric Hoists. A typical hoist is shown as the basis for the exploded parts illustrations; therefore, certain variations may occur from the information given. For this reason, always give the Hoist Serial Number, Catalog Number, Motor Horsepower,
Voltage, Phase, Frequency and Rated Load of Hoist when ordering parts.
Certain parts of your hoist will, in time, require replacement under normal wear conditions. It is suggested that these parts be purchased for your hoist as spares for future use. These parts are indicated by a (†) symbol at the right side of the parts reference numbers.
