INTRODUCTION

2703 SERIES

Auto Crane products have been engineered to provide safe, trouble-free, dependable service for many years when these products are properly used and maintained.

To assist you in obtaining the best service from your crane and to avoid untimely failure of the unit and / or the vehicle on which it is mounted, the following operating and service instructions are herein published, and it is specifically recommended that all operating and service personnel consider this manual as mandatory material for reading and study before operating or servicing Auto Crane products. It is highly recommended that crane owners, equipment managers and supervisors also read this manual.

For your convenience the overall dimensions of the 2703 series crane are on the

General Dimension Drawing. Maximum turning radius is shown at the outside point of the hoist actuator (M model) and the outside edge of the rotation gear motor (MR & PR model).

Remember, the crane adds weight to the vehicle. Adding weight may change the driving and riding characteristics of the vehicle unless the appropriate overload spring(s) are installed on the truck. The payload of the vehicle is reduced by the weight of the crane. The operator should exercise care when loading the vehicle. Distributing the payload on the vehicle evenly will greatly improve the driving and riding characteristics of the vehicle. A

minimum G.V.W. of 8,000 lbs. with two rear jacklegs (or outriggers) is recommended for mounting the 2703 series cranes. Crane side jackleg should extend

45" from centerline of truck chassis.

The 2703 series cranes are attached directly to your 12 volt truck electrical system. The power cable and retaining clips are included with the crane. A typical power cable mounting and hookup is shown on page

2-1.0.0. The performance of your new crane depends on the truck electrical system. The use of the low maintenance battery is not recommended for use on any Auto Crane product. The recommended alternator and battery that will give the longest life with the most useful duty cycle is a 60 amp. alternator with a 500 cold cranking rated battery. These specifications should be considered minimum.

Auto Crane Company issues a limited warranty certificate with each unit sold.

See last page for warranty policy.

It has always been Auto Crane Company policy to handle all warranty claims we receive as promptly as possible. If a warranty claim involves discrepant material or workmanship,

Auto Crane will take immediate corrective action. It is understandable that Auto Crane company cannot assume responsibility of liability when it is obvious that our products have been abused, mis-used, overloaded or otherwise damaged by inexperienced persons trying to operate the equipment without reading the manual.

Auto Crane will not assume responsibility or liability for any modifications or changes made to unit, or installation of component parts done without authorization.

Auto Crane maintains a strong distributor network and a knowledgeable Customer

Service Department. In most cases, an equipment problem is solved via phone conversation with our customer service department. The customer service department also has the ability to bring a local distributor, a regional sales manager, or a factory serviceman into the solution of an equipment problem. If, through no fault of Auto Crane Company, it is necessary to send an experienced factory

OPERATION OF UNIT

26. Make sure this manual has been thoroughly read by all crane operating personnel and supervisors.

27. A routine inspection of the crane should be mandatory before each operating day. Any defects should be corrected immediately.

28. At a job site the vehicle should be positioned so that the crane can adequately reach the load within the rated capacity (centerline of rotation to hoist hook).

29. Keep the vehicle as level as possible during operation.

30. For electric cranes, engage emergency brake and leave ignition on with transmission in neutral (or in park for automatic transmissions). Activate any crane power switches. For Auto Crane units requiring battery and hydraulic operation, engage emergency

brake, place gear selector in neutral, press clutch, activate PTO, release clutch and after hydraulic fluid is warm, set throttle control to proper engine speed.

31. Always use outriggers from the truck to the ground.

Be sure these are firm and adequately positioned.

When rotating, keep load as low to the ground as

possible.

32. Remove pendant control from cab or storage area. On smaller units, plug pendant into receptacle on crane.

On larger units, remove pendant control from guard and unwrap cable from boom. Do not operate crane until cable is unwound completely. On all cranes, detach hook from dead man. Crane is now ready for operation.

33. Always boom up before rotating so the boom will clear the required boom support.

34. When extending the boom, always maintain clearance between the boom crown and the traveling block or hoist hook.

35. Always observe safe and practical operation to avoid possible accidents. Refer to Safety Tips and

Precautions.

36. After completing lifting operations, return the boom to stowed position on the boom support. Avoid unneeded pressure on the boom support.

37. Store pendant control on proper location (in cab or on crane).

38. Return outriggers to stowed position. Make sure they are pinned in place or jacklegs are returned to compartment.

39. Check work area for any tools or equipment not stored.

40. Release throttle control, depress clutch and disengage

PTO. Deactivate any crane power switches.

41. Report any unusual occurrence during crane operation that may indicate required maintenance or repair.

42. NEVER use two cranes to support a load too large for either crane.

43. Spray all electrical equipment with special corrosion resistant coating. This eliminates rust or corrosion due to melting and freezing action of condensation.

OPERATION OF

OUTRIGGERS

For hydraulic outriggers:

1. Shift crane/outrigger control valve to

"outrigger" position.

2. While operating the outrigger control valves

(located on the outrigger cylinders) simultaneously operate the boom-up control switch. This will allow the hydraulic system to build pressure.

3. After outriggers are positioned, return crane/outrigger selector to "crane" position.

4. Crane is now ready to operate.

1-3.0.0

For manual outriggers:

1. Pull lock pins to release jack leg or drop down outrigger and move to outermost lock position.

2. Make sure lock pins are reinstalled properly.

3. Lower outrigger pad to firm ground and adjust foot to take out slack.

4. Crane is now ready to operate.

1. sections in contact with saddles, equalizer sheaves, or other sheaves where rope travel is limited

2. sections of the rope at or near terminal ends where corroded or broken wires may protrude

ROPE REPLACEMENT

58 Periodic inspection

A. The inspection frequency shall be determined by a qualified person and shall be based on such factors as:

1. expected rope life as determined by experience on the particular installation or similar installations

2. severity of environment

3. percentage of capacity lifts

4. frequency rates of operation

5. exposure to shock loads

Inspection need not be at equal calendar intervals and should be more frequent as the rope approaches the end of it's service life.

This inspection shall be made at least annually.

B. Periodic inspection shall be performed by a designated person. This inspection shall cover the entire length of the rope. Only the surface wires need be inspected. No attempt should be made to open the rope. Any deterioration results in appreciable loss of original strength, such as described below, shall be noted and determination made as to whether use of the rope would constitute a hazard: points listed above reduction of rope diameter below nominal diameter due to loss of core support, internal or external corrosion, or wear of outside wires; severely corroded, cracked, bent, worn or improperly applied connections;

C. Care shall be taken when inspecting sections subject to rapid deterioration such as the following:

59 No precise rules can be given for determination of the exact time for replacement of rope, since many variable factors are involved.

Continued use in this respect depends upon good judgement by a designated person in evaluating remaining strength in a used rope after allowance for deterioration disclosed by inspection. Continued rope operation depends upon this remaining strength.

60 Conditions such as the following shall be reason for questioning continued use of the rope or increasing the frequency of inspection:

A. in running ropes, six randomly distributed broken wires in one lay or three broken wires in one strand in one lay

B. one outer wire broken at the contact point with the core of the rope structure and protrudes or loops out of the rope structure. Additional inspection of this section is required

C. wear of one third of the original diameter of the outside individual wire

D. kinking, crushing, birdcaging, or any other damage resulting in distortion of the rope structure

E. evidence of any heat damage from any cause

F. reduction from nominal diameter of more than 1/64 in. (0.4mm) for diameters up to and including 5/16 in. (8 mm), 1/32 in. (0.8 mm) for diameter 3/8 in.

(9.5 mm) to and including 1/2 in. (13 mm), 3/64 in.

(1.2 mm) for diameter 9/16 in. (14.5 mm) to and including 3/4 in. (19 mm). 1/16 in. (1.6 mm) for diameter 7/8 in. (22 mm) to and including 11/8 in.

(29 mm), 3/32 in. (2.4 mm) for diameters 11/4 in.

INSPECTION, TESTING AND MAINTENANCE

GENERAL

G. In standing ropes, more than two broken wires in one lay in sections beyond end connections or more than one broken wire at an end connection.

H. Replacement rope shall have a strength rating at least as great as the original rope furnished or recommended by the crane manufacturer. Any deviation from the original size, grade, or construction shall be specified by a rope manufacturer, or a qualified person.

65 Before cutting a rope, seizing shall be placed on each side of the place where the rope is to be cut to prevent unlaying of the strands. On pre-formed rope, one seizing on each side of the cut is required. On non-preformed ropes of 7/8 in. (22 mm) diameter or smaller, two seizings on each side of the cut are required, and for non-preformed rope 1 in. (25 mm) diameter or larger, three seizings on each side of the cut are required.

61 Rope not in regular use: all rope which has been idle for a period of a month or more due to shutdown or storage of a crane on which it is installed, shall be given and inspection in accordance with above information before it is placed in service. This inspection shall be for all types of deterioration and shall be performed by a qualified person.

66 During installation care should be exercised to avoid dragging of the rope in the dirt or around objects which will scrape, nick crush or induce sharp bends in it.

62 Inspection records

A. frequent inspection- no records required

B. periodic inspections- in order to establish data as a basis for judging the proper time for replacement, a dated report condition at each periodic inspection should be kept on file. This report shall cover points of deterioration listed above.

67 Rope should be maintained in a well-lubricated condition. It is important that lubricant applied as a part of a maintenance program shall be compatible with the original lubricant and to this end the rope manufacturer should be consulted. Lubricant applied shall be the type which does not hinder visual inspection. Those sections of rope which are located over sheaves or otherwise hidden during inspection and maintenance procedures require special attention when lubricating rope. The object of rope lubrication is to reduce internal friction and to prevent corrosion.

ROPE MAINTENANCE

63 Rope should be stored to prevent damage or deterioration.

68 When an operating rope shows greater wear or well defined localized areas than on the remainder of the rope, rope life can be extended in cases where a section at the worn end, and thus shifting the wear to different areas of the rope.

64 Unreeling or uncoiling of rope shall be done as recommended by the rope manufacturer and with care to avoid kinking or inducing twist.

MAINTENANCE OF BATTERIES

Maintenance of Auto Crane unit batteries differs very little from the generally prescribed maintenance of any lead acid battery. All batteries must be kept properly

charged, properly filled with water, and relatively clean

.

Keep Properly Filled with Water

The battery should always be properly filled with water.

If the electrolyte level is allowed to fall below the top of the plates, the results become threefold:

Keep Properly Charged

1 The exposed portion of the plate will become sulfated.

Many things affect the proper charge to a battery, such as:

2 The portion of the plate exposed is not usable.

1 Regulator settings

3 That portion of the acid remaining becomes more concentrated and may cause more rapid deterioration of the remaining parts of the battery.

2 Proper tightness of belts on the alternator or generator

Keep A Relatively Clean Battery

3 Good, clean connections of all cables and wires at the following places:

A. Battery

B. Regulator

C. Starting motor

D. Alternator or generator

E. Ground connections (most important)

It is of extreme importance to keep the battery as fully charged as possible without overcharging, especially when vehicles are left outside for extended periods in extremely cold climates. A battery can freeze.

Freezing points for various specific gravities of acid are as follows:

The battery should be kept clean. Batteries filled with acid and which are not in use self-discharge to a limited degree because of the nature of the materials within the battery. If dirt is allowed to collect on the top of the battery (and this dirt absorbs moisture) and electrical path can be set up between the various terminals of the battery and the ground. Once such a path has been established, the self-discharge of the battery is accelerated. This also accelerates corrosion of the battery cables at the terminals.

Periodic Maintenance is Needed

Specific Gravity Freezing Temp.

(Corrected to 80ºF) Degrees F.

A definite program of periodic maintenance of all batteries should be conducted on a regular basis.

Periodic maintenance includes:

1.280 -90ºF

1.250 -62ºF

1.200 -16ºF

1.150 5ºF

1.100 19ºF

1

2

Checking belts for tightness on the charging equipment

Checking battery electrolyte levels

3 Checking cables for good connections

As shown, a half-charged battery (about 1.200 specific gravity) cannot stand for any length of time at 20ºF or it will freeze.

The main reason for keeping the battery as fully charged as possible without over-charging is to ensure that power is available even though the vehicle has been standing for some time.

4 Cleaning where corrosion is apparent

When corrosion is cleaned off, the cable terminals and battery terminals should be coated with a light coating of petroleum jelly before they are replaced. When terminals are cleaned, the top of the battery should be cleaned with a mild solution of soda water.

1-6.1.0.

MAINTBAT 9/98

MAINTENANCE OF BATTERIES

Low Maintenance Batteries

(Maintenance Free)

should be attempted for an extended time. This usually will recover a badly sulfated battery.

Low maintenance batteries should not be used on

Auto Cranes or trucks equipped with Auto Cranes.

The batteries are not designed for "deep" discharge.

Replacing a Battery

If it is necessary to replace a battery, and a dry charge battery is used, the following procedure applies:

Testing Your Battery

1 Fill the battery with electrolyte of the proper specific gravity.

If the condition of the battery is in question, it should be removed from the vehicle, taken to the shop, and allowed to reach room temperature. It should then be recharged until specific gravity readings taken at one-half hour intervals. If the specific gravity readings are fairly uniform, the battery should be checked with a high rate tester. Use the tester in accordance with the manufacturer's instructions. The high rate tester is the best method to test a questionable battery.

2 Place the battery on charge according to the manufacturer's instructions.

It is essential that the second step above be followed to ensure that the battery going on the vehicle is fully charged.

If, after charging, it is noted that the specific gravity reading of one cell is 30 points less than any of the other cells, it may be assumed that the cell is bad and that the battery should be replaced. If all cells are uniform but not up to full charge, a low rate of charge

It is also very important that the battery hold-downs be checked periodically to ensure that the batteries are properly positioned to avoid vibration problems, breakage of cables or terminals. Care must be taken to avoid cracking or breaking containers or covers by tightening hold-down fixtures excessively. They also must not be so loose that breakage results from a hold-down that is too loose.

1-6.2.0.

MAINTBAT 9/98

LIFE OF WIRE LINE

So many variable factors can cause the deterioration of wire line cable that it is not possible to determine a definite life expectancy. Some of these factors are:

• Load being handled.

• Corrosive conditions.

• Maintenance of the unit:

Keep the sheaves turning freely.

Maintain tension on cable to insure proper spooling.

Avoid kinks in cable.

Avoid abrasive action and contact with sharp corner.

• Frequency of use.

Auto Crane units, up to 2,400 pound ratings use 3/16 inch diameter galvanized pre-formed 7 x 19 aircraft cable. This cable has a working strength, when new, of 4,200 pounds.

It is recommended when 1,200 pound loads are exceeded to use a two part line with a traveling block. This will ensure a 3.5 to 1 safety factor when the cable is new.

Keeping the above factor of safety in mind and knowing the kind of loads that will be handled, the user can determine by inspection of the cable as to when it should be replaced.

Items to look for while inspecting the cables are:

Broken strands.

Kinks and flattened sections.

Corrosion and abrasion.

WIRE LINE LUBRICATION

Lubrication of the wire line serves two important purposes:

• Prevent corrosion.

• Reduce wear due to flexing and abrasion caused by contact with the sheaves, rollers, and cable on the drum.

Preparation

Remove rust and foreign matter with a wire brush and wipe clean. Be sure cable is dry.

Application

Method 1: Dip a brush into a light weight motor oil and apply. In some cases, dip a rag or a piece of sheepskin into the lubricant and swab the lubricant on to the rope.

Method 2: Apply a heavier lubricant such as a grease gun lubricant with hands while wearing leather gloves. (Leather gloves give greater protection and less penetration of the grease than canvas gloves.)

TROUBLESHOOTING 2703

PROBLEM CAUSE/SOLUTION

CRANE WILL NOT HOIST UP OR

DOWN.

CAUSE:

Bad relay, crane not grounded properly, or power cable not connected to

12V power source. Bad switch in pendant, broken wire in pendant connector, pendant not plugged together properly, wire on relay not in proper place or lead wires to motor not connected properly.

SOLUTION:

Problems can be solved by replacing bad relay, grounding the crane properly to the truck chassis, connecting the power cable properly to 12V+ power source, switch in pendant can be replaced, cord in remote control can be replaced, check connector on cord to make sure of contact of all the prongs on it are plugged together correctly, make sure wires on relays are according to the wiring print supplied with each new crane in the owner book and also wires going to motor are connected properly. NOTE: 12V

must pass through opposite relay to complete circuit.

WITH LOAD SENSOR (OPT.)

CRANE WILL NOT HOIST UP OR

BOOM UP AND DOWN.

CAUSE:

Crane is overloaded.

Sensor switch is bad.

Bad connection to relays.

SOLUTION:

Hoist down. Do not overload crane. Replace sensor switch. Check for loose or damaged wiring.

CRANE RUNS UP OR DOWN ANY

TIME POWER SOURCE IS

CONNECTED.

CAUSE:

Relay stuck in run position which will let crane run up or down any time

12V power is connected. Wires shorted together in remote control. Lead or cable can also cause this problem. Wires jumped across relay in wrong place can cause crane to run all the time.

SOLUTION:

Problem can be solved by checking the relays and replacing the bad one or removing jumper wires from the relays or replacing the remote control cord or switch.

TROUBLESHOOTING 2703

HOW TO CHECK RELAY:

Our relays are normally closed across the bottom posts

(C & D). When activated, they will open across (C &

D) and close across A & B). To activate these relays, use 12V positive and 12V negative wires and place them on posts (F & E). You may place 12V+ on post F or E as long as you place 12V on the remaining post (F

& E) using an ohm meter or test light. Check across posts (A & B). You should get an ohm reading or your test light should be on when you have the relay activated. With the relay still activated, check across posts (C & D). You should have no ohm reading or test light at this point with relay activated. (At this point, disconnect 12V+ and 12V– from posts (F & E). This should let relay return to its normal position. Using your ohm meter or test light again, check the relay across posts (A & B). If relay is working correctly, you should have no reading at all. Then check across posts

(C & D). You should have an ohm reading or test light should be on. If you get the above results, relay is okay.

If you get any variation in the above explanation on the relay you are checking, check the relay again. If it still shows a difference, the relay is bad and should be replaced. NOTE: The above explanation is with

relays completely disconnected from all wires on motor circuits and ground wires. These circuits can give you false readings sometimes.

Frequently Answers and Questions

What is the minimum GVWR required for the 2703 Series cranes?
The minimum GVWR required for the 2703 series cranes is 8,000 lbs.
What are the recommended specifications for the alternator and battery for the 2703 series cranes?
The recommended alternator is a 60 amp alternator with a 500 cold cranking rated battery.
What are the load capacities of the 2703 Series cranes?
The load capacities vary depending on the boom length and are listed in the Load Chart on page 19.
How do I operate the outriggers on the 2703 Series cranes?
The outriggers can be either hydraulic or manual. For hydraulic outriggers, shift the crane/outrigger control valve to "outrigger" position, operate the outrigger control valves simultaneously, and return the valve to "crane" position after positioning the outriggers. For manual outriggers, pull the lock pins, move the jack leg or outrigger to the outermost lock position, and lower the outrigger pad to firm ground.
What are the minimum clearance requirements for operating near high voltage power lines?
For lines rated 50 kV or below, the minimum clearance is 10 ft. For higher voltages, refer to Table 1 on page 2-3.2.0.
What are the inspection requirements for the 2703 Series cranes?
The inspection requirements are divided into two general classifications: frequent inspections (daily to monthly intervals) and periodic inspections (one to twelve intervals). Frequent inspections include checking for malfunctioning control mechanisms, leaks, worn parts, and rope reeving. Periodic inspections cover deformed or corroded members, loose bolts, worn sheaves and drums, worn or damaged parts, and hydraulic and pneumatic hoses, pumps, motors, and valves.
