Application Information This hoist is intended for general industrial use in the lifting and transporting of freely suspended material loads within its rated load. Prior to installation and operation, the user should review his application for abnormal environmental or handling conditions and to observe the applicable recommendations as follows: a. Adverse Environmental Conditions. Do not use the hoist in areas containing flammable vapors, liquids, gases or any combustible dusts or fibers. Refer to Article 500 of The National Electric Code. Do not use this hoist in highly corrosive, abrasive or wet environments. Do not use this hoist in applications involving extended exposure to ambient temperatures below - 10°F or above 130°F. b. The supporting structure and load attaching devices should have a load rating at least equal to that of the hoist. c. This hoist is not suitable for use in uncovered outdoor locations or areas containing explosive dust, vapors or gases. d. The installation area must provide safe operating conditions for the operator, including sufficient room for the operator and other personnel to stand clear of the load at all times. 2-2. Trolley Installation Yale trolleys can be mounted on American Standard I Beams from 6 to 18 inches high. Adjustment for different beam dimensions is accomplished with the proper placement of spaced washers as described below. a. "I"-Beam Adjustment. Adjustment for "I" beam sizes and tolerances is accomplished by locating the spacer washers as shown in Figures 2-I, 2-2, and 2-3. Tables 2-I, 2-2, and 2-3 provide an approximate guide to washer placement. Be sure to use the proper Table, based on lift and trolley-type of the particular installation. BEAM MANUFACTURING TOLERANCES ALLOW WIDE VARIATIONS FROM HANDBOOK FLANGE WIDTHS, AND SLIGHT CHANGES TO RECOMMENDED WASHER DISTRIBUTION MAY BE NECESSARY TO SUIT SPECIFIC INSTALLATIONS. b. Lifting of Hazardous Loads. This hoist is not recommended for use in lifting or transporting hazardous loads or materials which could cause widespread damage if dropped. The lifting of loads which could explode or create chemical or radioactive contamination if dropped requires fail-safe redundant supporting devices which are not incorporated into this hoist. The particular beam on which your hoist is to be installed should be measured and trolley spacer washers adjusted as required to achieve a clearance of ;/.,2" to 1/8". c. Lifting of Guided Loads. This hoist is not recommended for use in the lifting of guided loads, including dumbwaiters and non-riding elevators. Such applications require additional protective devices which are not incorporated into this hoist. Refer to your state and local regulations governing the requirements for elevator and dumbwaiter installations. Trolleys can be mounted on beam radii as small as 4 feet. Slightly increased spacing may be required when the trolley is mounted on curved beams to maintain freedom of movement. The load pin nuts for the trolleys require a tightening torque of 100 ft. lbs. Refer to Figures 2-1, 2-2, and 2-3 for nut identification. 1-6. Warranty Every hoist is thoroughly inspected and tested prior to shipment from the factory. Should any problems develop, return the complete hoist prepaid to your nearest Yale Authorized Warranty Repair Station. If inspection reveals that the problem is caused by defective workmanship or material, repairs will be made without charge and the hoist will be returned, transportation prepaid. b. Periodic Inspection. The trolley should be inspected periodically for evidence of excess wear or overload. Parts should be replaced as required. This warranty does not apply where: (1) deterioration is caused by normal wear, abuse, improper or inadequate power supply, eccentric or side loading, overloading, chemical or abrasive actions, improper maintenance or excessive heat; (2) problems resulted from repairs, modifications or alterations made by persons other than factory or Yale Authorized Warranty Repair Station personnel; (3) the hoist has been abused or damaged as a result of an accident; (4) repair parts or accessories other than those supplied by Yale are used on the hoist. Equipment and accessories not of the seller's manufacture are warranted 2-3. Power Supply Connection c. Lubrication. Trolley wheels are equipped with sealed, lifetime lubricated, precision ball bearings which should not require lubrication for the normal service of the trolley. a. Disconnect power before making connections. b. Voltage supplied to the hoist should be within plus or minus 10% of the voltage specified for the hoist. Hoists are tagged at the factory with a tag indicating the voltage for which the hoist is wired. Standard single-phase hoists are convertible from 115 to 230 volts. Standard single-speed, 3 phase hoists are convertible from 460 volts to 230 volts. See the wiring section (paragraph 7-1) for voltage conversion instructions. Page 3 For more information contact: Sievert Crane and Hoist, (708) 771-1600, [email protected], www.sievertcrane.com SECTION I - INTRODUCTION c. National Electrical Code (ANSI Cl) and local electrical codes should be consulted and proper disconnects, branch circuit protectors, and wiring provided. d. Power cables furnished with the hoist have a green colored ground wire which must be securely connected to the electrical system ground. e. When installing a three-phase hoist, make only temporary connections at the power line. Push the "UP" button and observe the direction of the hook. If it raises, the phasing is correct and permanent connections may be made at the power line. If the load block lowers when the "UP" button is pushed, release the button immediately since the limit switches will not operate to protect the hoist from overtravel. Reverse the red and black wires at the power line connection to correct the hook direction. 2. If brake operation is normal with a light load, repeat the above procedure with approximately one-half rated load, again running the hoist through its full lilt stroke for a few cycles. Check again for hook drift. 3. If brake operation is normal with one-half rated load, attach rated load to the hook and continue the break-in procedure. The hoist shall operate smoothly and the brake should prevent hook drift in excess of one inch as rated load. See Paragraph 5-3 if motor brake adjustment is required. 4. Set the load on the floor. Disconnect the dead end of the wire rope as described in paragraph 5-4.a.8. Allow the dead end to rotate, in order to remove all twist from the rope. Reconnect the dead end and be sure to replace and tighten the anchor screws. CAUTION Do not change connections in the hoist or the pushbutton assembly. 2-4. Vent Plug This hoist has an oil-bath transmission. For shipping purposes, a non-vented fill plug (39. Figure 8-4) was installed at the factory. A vented plug is located in an envelope tied to one of the hoist end covers and must be installed in place of the non vented shipping plug before operating the hoist. 2-5. Wire Rope Lubrication It is important that the wire rope is lubricated before the hoist is put into service. Wire rope lubricant is packed with each hoist. For lubrication instructions, see paragraph 5-5a. Additional lubricant is available from your Yale distributor. Specify Part No. 14J49. 2-6. Testing a. Before placing the hoist into operation, check for proper limit switch operation. Push the "UP" button and verify that the hook block stops at least 2 inches from the bottom of the hoist. Run the hoist down to its lower limit. At least 2 wraps of wire rope should remain on the drum. If either switch is not correct, adjust according to the procedure outlined in paragraph 5-2. Note The upper and lower limit switches are factory set to provide the maximum allowable hook travel. This travel adjustment should not be increased. However, the switches may be adjusted to stop the hook sooner at either end of its travel. b. Wire rope life can be extended by a short breaking-in period before the hoist is put into service. During this breaking-in period, a small amount of twist may show up in the rope. This twist should he removed as described below. This break-in can be done at the time of hoist testing: 1. Attach alight load to the hook and run the hoist through its full lift stroke fora few lifting and lowering cycles. Check for hook drift. The hook should not drift more than one inch.

Page 7 For more information contact: Sievert Crane and Hoist, (708) 771-1600, [email protected], www.sievertcrane.com SECTION III - OPERATION 3-1. General This section presents information concerning the proper operation on the Yale Electric Wire Rope Hoist. It is not intended to serve as a handbook on rigging. Rigging, the process of moving heavy loads using mechanical devices, requires special knowledge and equipment. For information on the safe use of slings and similar rigging gear, users are urged to consult a textbook on rigging. 3-2. Safety Notes b. The wire rope should not be wrapped around the load. Use proper slings. c. Be sure the wire rope is properly seated in the drum groove and in the bottom block sheave. d. Bring the hook into engagement with the load and make sure it is well seated before proceeding to lift the load. Be sure that the load is equalized on all supporting ropes. e. Lift the load just clear of its supports and stop the hoist to check for proper brake operation. a. Inspect the hoist for any sign of loose, broken, or malfunctioning parts (see Section IV). Any malfunctioning hoist should be tagged as "out of order" and removed from service until the defect is corrected. f. Avoid letting the hook or load swing excessively while moving a trolley suspended hoist. b. Before starting the hoist, the operator should be certain that all personnel are clear. This hoist is equipped with a factory-calibrated overload limiting clutch, which permits lifting loads within rated capacity and prevents lifting excessive loads which could damage the hoist. If the load exceeds the lifting capability of the overload clutch, the hoist will not lift the load, but the motor will run as long as the "UP" button is pressed. Repeated attempts to lift an excessive load will overheat the overload clutch and cause permanent damage to the clutch. c. Do not lift more than the rated load of the hoist. d. Do not lift people or loads over people. e. Avoid jogging controls or quick reversals of suspended loads. f. Do not leave a suspended load unattended. 3-4. Overload Limiting Protection g. The operator should have a clear view of the load anytime it is moving and should be sure that the load does not contact any obstructions. CAUTION h. Read ANSI B30.16 Safety Standard for Overhead Hoists. 3-3. Handling The Load a. Align hoist directly over load. Avoid side pull, since this can cause the wire rope to jump grooves, or overwrap itself. This condition will quickly damage the wire rope. The overload limiting clutch is an emergency protection device. It should not routinely be used to measure the maximum load to be lifted. Page 8 For more information contact: Sievert Crane and Hoist, (708) 771-1600, [email protected], www.sievertcrane.com SECTION IV - INSPECTION 4-3. Periodic Inspection 4-1. General A scheduled inspection routine should be established for this hoist based upon severity of use and environmental conditions. Some inspections should be made frequently (daily to monthly) and others periodically (monthly to yearly). It is suggested that an Inspection and Maintenance Check List and an Inspector's Report similar to those shown in Figures 4-1 and 4-2 be used and filed for reference. All inspections should be made by a designated inspector. Special inspections should be made after any significant repairs or any situation causing suspicion that the hoist may have been damaged. Any hoist which has been removed from service for an extended time should receive an inspection as described under Periodic Inspections. ANSI B30.16, Safety Standard for Overhead Hoists, provides guidelines for hoist operation and inspection. The exact period for the following inspections will depend on the anticipated severity of hoist use. Determination of this period should be based on the user's experience. It is recommended that the user begin with a monthly inspection and extend the periods to quarterly, semiannually, or annually, based on his monthly inspection experience. a. Clean hoist of any dirt or foreign material. Inspect bottom block for accumulation of debris. b. Perform all frequent inspections listed above. c. Check for loose bolts, screws and nuts. d. Check housings, load block, and other parts for wear, corrosion, cracks or distortion. Check for abnormal openings between housing sections. e. Check motor brake for worn discs, oil contamination or excessive clearance (see paragraph 5-3). CAUTION f. Check mechanical load brake function (paragraph 4-4). g. Inspect the entire length of wire rope for deficiencies. See WIRE ROPE INSPECTION, paragraph 4-5. Any unsafe condition disclosed by any inspection must be corrected before operation of the hoist is resumed. h. Inspect hooks and suspension parts for cracks, distortion or extreme wear. 4-2. Frequent Inspection a. Check pushbutton station, brake, and limit switches for proper operation. b. Check hooks for deformation, chemical damage, or cracks. Bent hooks or hooks damaged from chemicals, deformation, cracks, or having excessive throat opening (see paragraph 4-6) should be replaced. Visible deformation of any hook may be evidence of hoist abuse and overloading and indicates that a thorough inspection of the complete hoist should be made. c. Check that bottom hook swivels freely. d. Check for missing, bent or otherwise damaged hook latches. i. Inspect hooks for cracks using magnetic particle, dye penetrant or other crack detecting methods. j. Check limit switch set points and reset if necessary (see paragraph 5-2). k. Inspect all wiring for defective insulation, and check to be sure all electrical connections are tight. Check motor reversing contactor or relay for burned contacts. l. Inspect for oil leaks. Check oil level. m. Inspect for missing or illegible capacity or warning labels. n. Inspect the supporting structure for continued ability to support the hoist rated load. e. Check pushbutton and power cord for cuts or other damage. f. Check wire rope for wear, twist, distortion or kinks.

Note Do not allow either screwdriver to contact brake disc (see Figure 8-9, Index No. 7). d. Carefully pry open motor brake (close solenoid gap) and observe action of load. If the load accelerates, the mechanical load brake is malfunctioning and must be repaired. 14019 Figure 4-3 Load Brake Function Check List Page 11 For more information contact: Sievert Crane and Hoist, (708) 771-1600, [email protected], www.sievertcrane.com 4-5. Wire Rope Inspection by inspection. Safety of rope operation depends upon this remaining strength. Conditions such as the following should be sufficient reason for questioning rope safety and consideration of replacement. a. Make a thorough inspection or the wire rope at least once each month and keep a written, dated and signed report of rope condition on file. Any deterioration, resulting in appreciable loss of original strength, such as described below, shall be carefully noted and determination made as to whether further use of the rope would constitute a safety hazard. See Figure 4-4 for identification of wire rope components. 1) Twelve randomly distributed broken wires in one rope lay length or four broken wires in one strand in one rope lay length. One lay is the length, parallel to the longitudinal axis, in which a strand makes one complete turn about the axis of the rope. See Figure 4-4. 1) Reduction of rope diameter below nominal due to loss of core support, internal or external corrosion or wear of outside wires. 2) Two wires broken adjacent at the end fittings. 2) A number of broken outside wires and the degree or distribution or concentration of such broken wires. 4) Kinking, crushing, birdcaging or any other damage resulting in distortion of the rope structure. 3) Worn outside wires. 5) Evidence of any heat damage from any cause. 4) Sections of rope which are normally hidden during inspection or maintenance procedures, such as parts passing over sheaves, should be given close inspection as these are points most subject to deterioration. 6) Reductions from nominal 1/4 inch diameter to 15/64 inch. 3) Wear of one-third of the original diameter of outside individual wires. 5) Corroded or broken wires at end connections. CAUTION 6) Corroded, cracked, bent, worn or improperly applied end connections. Use only wire rope assemblies supplied by our company since replacement rope assemblies must be of the same size, grade and construction rope and have the same swagged end fittings as the original rope assembly. 7) Kinking, crushing, cutting or unstranding. b. No precise rules can be given for determination of exact time for replacement of wire rope, since many variable factors are involved. Safety in this respect depends largely upon the use of good judgment in evaluating remaining strength in the used rope after allowance for deterioration disclosed 4-6. Hook Throat Opening Check throat opening as indicated in Figure 4-5. Replace hook if measurement exceeds the allowable. 14020 14021 *Dimension of throat opening with internal latch.

General b. Adjusting Lower Limit (Zinc Nut) This section provides instructions for the most common routine maintenance and adjustments. Major repairs are not within the scope of this manual and should be referred to qualified service facilities. 1) Carefully lower the load block to a point where at least 2 wraps of wire rope remain on the drum. 2) DISCONNECT POWER from the hoist and remove the short end cover. 3) Adjust the zinc limit switch nut in the same manner described above for the brass nut. SAFETY NOTE Always remove load and disconnect hoist from power supply before removing end covers or making repairs. 4) Replace the short end cover and reconnect power to the hoist. 5-2. Limit Switch Adjustment Limit switches are provided to protect the hoist against damage resulting from over travel. For easy identification the upper (No. 2, Figure 5-1) and lower (No. 3, Figure 5-1) limit switch adjusting nuts are colored brass and zinc respectively. Each limit switch nut has ten slots for adjustment, and the increment of adjustment is such that one slot is equivalent to approximately 3/4" of hook travel. Care should be exercised when adjusting either limit of travel. a. Adjusting Upper Limit (Brass Nut). 1) Carefully raise the load block to a point where its top is 2" or more from the hoist housing. 2) DISCONNECT POWER from the hoist and remove the short end cover. 5) Carefully lower the load block to its lower limit and observe if it stops automatically at the desired level. At least 2 wraps of wire rope should remain on the drum. NOTE If upper and lower limits are not operating satisfactorily, repeat adjustment. 5-3. Motor Brake Adjustment When properly adjusted, the multiple disc motor brake should release promptly, operate without noticeable chatter, and stop the load with no more than one inch of drift. If the hoist hesitates to lift the load promptly when the pushbutton is depressed, the brake should be adjusted per the following procedure. 3) With a screwdriver, pry the spring guide plate (No. 1, Figure 5-1) out of the slots in the colored limit switch nuts (Nos. 2 and 3). 14023 Figure 5-2 Motor Brake Adjustment a. Remove any load and DISCONNECT POWER from hoist. b. Remove the short end cover. c. Referring to Figure 5-2, check the gap between armature (A) and frame (B). The correct gap is .015". 14022 d. Adjust the gap by turning the three lock nuts (F) and check with a feeler gauge to be sure the gap is the same on both ends of the solenoid. Figure 5-1 Limit Switch Adjustment 4) Turn the slotted brass nut (No. 2) toward its limit switch until the switch clicks. CAUTION 5) Release the spring guide plate and be sure it snaps back into the slots in both nuts. Do not disturb the other slotted nut if it has been previously set. 6) Replace the short end cover and reconnect power to the hoist. Be sure the bottom of the armature does not touch the splined adapter (H). As wear occurs, the original clearance will be reduced. When this clearance is gone, the brake discs must be replaced. 7) Carefully raise the load block to its upper limit and observe to see if it stops automatically at the desired point. Do not allow the load block to run into the hoist drum. The stopping point should be at least 2" below the hoist drum. e. Replace short end cover and reconnect power. If the brake still chatters or is hesitant to release, refer to Section V4, Troubleshooting.

DO NOT DISCONNECT THE WIRES FROM THE LIMIT SWITCHES. 17) Adjust the limit switched per paragraph 5-2. 5) With the end cover off, connect hoist to power supply. Be sure the green wire is grounded. 6) Carefully jog the "DOWN" button until all the old rope is run off and the drum socket openings are accessible. 7) DISCONNECT POWER from the hoist. 8) Remove the equalizer sheave (A, Figure 5-4 or 5-5) by removing one retaining ring (B) and the sheave pin (C). Clean and inspect these parts. 9) Slide the sleeve fittings out of the drum sockets and out of the block covers. Remove and discard the old rope. 10) Place paper on floor to protect the new wire rope from dirt and grit. Stretch the new rope out in one length and relieve any twist. The double the rope by bringing the two sleeve fittings together. 11) Pass each sleeve fitting through the rope openings in the block covers only. The block should remain disassembled at this point. 12) Insert each sleeve fitting into the drum sockets, making sure the fittings are properly seated. 18) Lubricate the wire rope for paragraph 5-5a. Test the hoist and break-in the wire rope per paragraph 2-6b. 5-5. Lubrication Proper lubrication is necessary for long, trouble-free hoist operation. Refer to the following and to Table 5-1, Recommended Lubrication Schedule, for lubrication points, type of lubricant and frequency of lubrication. a. Wire Rope: Lubrication of the wire rope is important. The action within the rope as it moves over the drum or around the sheave is for the strands to slide one against the other. Lubrication will reduce this friction and prevent the entrance of moisture which can cause corrosion. Frequent light applications of lubricant are better than infrequent heavy applications. For best results, use Yale Wire Rope Lubricant (Part No. 14J49), or other wire rope lubricant. As alternative, use SAE 30 motor oil. b. Gearing: The gear case of the hoist is filled at assembly with 46 oz. of a gear oil containing special friction-reducing additives. Page 15 For more information contact: Sievert Crane and Hoist, (708) 771-1600, [email protected], www.sievertcrane.com c. Limit Switch Shaft: To prevent rust, the threaded limit switch shaft should be given a light coat of grease or sprayed with a general purpose lubricant. WARNING The use of gear oils other than that recommended in Table 5-1 can cause brake chatter or can render the load brake incapable of holding a load. A 46 oz. container of this oil is available from YaleLift-Tech. (Part No. 14J1). d. Hook Bearing: Apply a few drops of SAE 30 oil around the edge of the bearing. a. To check the oil level, remove the 1/8" pipe plug from the side of the hoist. With the hoist hanging level, transmission oil should be even with the edge of the tapped plug hole. b. The length of time between necessary oil changes will depend on the severity of use the hoist receives. In general, the oil should be changed every 12 months of normal operation, or every 200 hours of actual hoist on-time. Very heavy use or operation in high ambient temperatures (over 105°F) will require that oil be changed more often. An indication of the need for oil replacement is load brake noise. If an erratic tapping sound is made when lowering a load, the oil should be changed. e. Sheave Bearings: At periodic inspections (see Figure 4-1), and when the wire rope is replaced, wash out the old grease with solvent and pack with new grease. f. Trolley Gear Box: At periodic inspections (see Figure 4-1) check grease level by removing end cap (22, Figure 8-11). The gear box should be approximately half full of grease. In general, the trolley gear box lubricant does not require changing. g. Trolley Wheel Gears: Apply a light coat of grease to the pinion and both gears. Table 5-1.
