POWER SOURCE (PTO DRIVEN)Integral-mounted hydraulic pump and PTO application. Other standard power sources may be used - minimum power requiredis 8 horsepower based on 5 GPM at 2350 PSI.

POWER SOURCE (ELECTRIC MOTOR)Power is supplied to the electric motor by a solenoid connected to the 12VDC truck battery. The chassis must be equipped with a4000 watt Delco Freedom battery (or equivalent) connected in parallel to the chassis’ standard heavy duty battery. The chassismust be equipped with a heavy-duty alternator (63 amp. for GM vehicles and 60 amp. for Ford vehicles). For best results, a 130-amp alternator is desirable.

ROTATION SYSTEMTurntable bearing with external worm gear powered with a high-torque hydraulic motor through a self-locking worm.

CYLINDER HOLDING VALVESThe base ends (extend side) of the lower boom and extension cylinders are equipped with integral-mounted counter-balancevalves to prevent sudden cylinder collapse in the event of a hose breakage or other hydraulic component failure.

The extend side of the lower boom cylinder is equipped with a 10 GPM counter balance valve. The counter balance valve servesseveral functions. First, it is a holding valve. Secondly, it is designed to control the speed at which the lowering functionoperates, and allows that motion to be metered under load. Finally, it prevents the loss of an excess amount of oil in the event ofa hose failure. Only the oil in the hose, at the time of the failure, will be lost.

EXCESSIVE LOAD LIMIT SYSTEM (ELLS)Overloading of the crane is limited by the ELLS. This is done by disarming the crane functions which make possible theapplication of greater than allowable stress to the crane structure and components. Functions controlled by the ELLS are winchup, extension out and lower boom down. To relieve the situation, the operator may set the load down (winch down) or retract theextension boom (extension in).

WINCHThe winch is powered by a hydraulic motor through a 38:1 ratio worm gear with a mechanical brake. Line speed is 25 ft/min (7.6m/min) at optimum oil flow of 5 GPM (18.9 liters/min) and 12 ft/min (3.8 m/min) with 2 part-line. Maximum single-line capacity ofthe winch is 2500 lbs (1134 kg). The winch is equipped with 65' (19.81m) of 5/16" (0.79cm) 6 x 25 FW PRF RRL IWRC IPS wirerope. A nylon sheave riding on a lubricated needle bearing is located at the tip of the extension boom. The ratio of winch drumand sheave pitch diameter to wire rope diameter is 18:1. An anti-two block device is included to prevent the lower block or hookassembly from coming in contact with the boom sheave assembly.

HYDRAULIC SYSTEM (PTO DRIVEN)Open-centered, full-pressure system that requires 5 GPM (18.9 liters/minute) optimum oil flow at 2300 PSI (159 bar). 4-spool,stack-type, electric, remote-control valve with 30' (9.14m) control cable. System includes separate oil reservoir, suction-linestrainer, control valve and return-line filter.

ELECTRO-HYDRAULIC SYSTEM (TWO-SPEED/AUTO-SHIFT)Open-centered, full-pressure system that features a 2-stage hydraulic pump, with the first stage delivering 1.5 GPM (5.7 liter/min)and the second stage delivering 3.5 GPM (13.2 liters/min) at 2300 PSI (159 bar). The operation of the circuit automatically shiftsfrom high speed to low speed when the crane reaches a certain pressure or load level. The control valvebank is a 4-spool, stacktype, 12VDC valve system. The system includes a 5 gallon (18.9 liter) hydraulic reservoir, 10-micron spin-on-type return filter, ahydraulic pump driven by a totally enclosed fan cooled 12VDC motor and all necessary hoses and fittings.

INSTALLATION

CRANE INSTALLATION

GENERAL INSTALLATIONThis section is intended to serve as a guide in theinstallation of the IMT 2020 crane. Since eachinstallation is considered unique, certain components,such as the power unit’s battery cable, must be alteredto fit the chassis.

CHASSIS INFORMATIONThe crane is designed for use with an IMT bodyinstalled on a vehicle meeting the minimum chassisrequirements as specified in Section 1.

If this crane is being installed on any body other thanan IMT mechanic body, check with IMT to determinethe suitability of that body.

WARNINGTHE USE OF THIS CRANE ON A BODY NOT CAPABLEOF HANDLING THE LOADS IMPOSED ON IT BY THECRANE, MAY RESULT IN SERIOUS INJURY OR DEATH.

CRANE INSTALLATIONThe crane requires a mounting space of at least 17-7/16" wide by 17" long. If necessary, the truck body canbe reinforced to give sufficient strength to support thecrane in its operating condition. Locate and drill the four13/16" holes (see drawing below). Use a pilot drill firstand then the 13/16" drill. Cut the 4" diameter hole witha saw after starting with a drill. Deburr all holes. Liftthe crane into position on the body. Use a lifting devicecapable of supporting the crane - 830 lbs (376 kg) or920 lbs (417 kg), dependent on model.

Install the bolts, lockwashers, flat washers and nuts tosecure the crane to the chassis (see drawing). Torquethe bolts to 200 ft. lbs. (27.66 kg-m).

NOTEIN ADDITION TO THESE SPECIFICATIONS, A HEAVY-DUTY BATTERY AND ALTERNATOR ARE REQUIRED.IT IS RECOMMENDED THAT THE VEHICLE HAVEPOWER STEERING AND DUAL REAR WHEELS.

IMT RECOMMENDS ADHERENCE TO THE UPPER LIMITOF THESE SPECIFICATIONS FOR BEST SYSTEMPERFORMANCE.

BODY REINFORCEMENTIf, after talking with the factory, it has been determinedthat the body will not support the crane with the full,rated load, the body can be reinforced as shown below.Use 1/4" fillet welds and an AWS qualified welder.

CONTROL VALVE TROUBLESHOOTINGGENERALThis section describes the operatingcharacteristics of the main control valvebankused on this model of crane. It also providestroubleshooting information which applies to thisvalvebank. See figure on following page forreference.

ELECTRICAL-AMP DRIVER

POWER LEDThe Power LED illuminates red while power isbeing applied to the valve amplifier. If the LED isnot illuminated, no power is being applied to thevalve amplifier.

If the Power LED does not function as described,inspect input wiring and repair or replace asnecessary. When input power is applied, the LEDshould illuminate.

PMW% LEDThe PMW% LED indicates the condition of theoutput current flowing to the proportional valve.The LED will change colors from, red to yellow togreen. The change of colors indicates thevariance of current flowing to the proportionalvalve. Red indicates minimum current and greenindicates maximum current. This represents theflow condition going from low flow (red) tomaximum flow (green), thus varying the speed ofcrane functions.

If the LED stays red, as the speed control triggeris activated, a dead short is present in the circuit.This could be the result of a wiring problem,shorted out proportional coil, etc. Inspect thewiring and replace the proportional coil, ifrequired.

MIN POTENTIOMETERThe Min adjustment pot will be used to set theminimum amount of movement of an indi-vidual function at the valvebank when thecorresponding function switch at the handsetis depressed. To adjust, set engine at highspeed control setting. Depress the “Rotation”function switch at the handset. Adjust the Minpot at the AMP driver card clockwise untilcrane begins to rotate or counterclockwiseuntil motion begins to stop. No other electricaladjustments are required to properly operatethe crane.

HYDRAULICS-VALVEBANK

RELIEF VALVEThe relief valve limits the maximum systempressure. Pressure limits the amount of torque orforce an actuator will see. This pressure is presetto 2300 psi at 5 gpm. If the relief valve should fail,it would likely stick open. This would preventsystem pressure from developing and cause alack of torque/force at the actuator. The reliefvalve can be changed easily by screwing it outand replacing with a new one.

PROPORTIONAL VALVEThe proportional valve varies the oil flow to theindividual crane functions. Doing so dictates thespeed of the crane functions. As the electricalcurrent increases to the valve, by using thetrigger on the control handle, more oil is porteddownstream to the crane function. If the valve coilburns out, the operator would be unable to varythe flow to the crane functions. If the valve spoolbecomes stuck, the operator would be unable tovary the downstream flow. If speed control is theproblem, it is likely an indication of a proportionalvalve problem. It is necessary to verify thatcurrent is flowing to the coil correctly, and that it isnot an electrical problem.The proportional valvecan also be operated manually for test purposes.The valve stem can be screwed out manually toport oil downstream. Doing so will manuallyposition the valve spool and hold it in the manuallycommanded position.

DIRECTIONAL VALVESThe directional valves (4) control the direction ofthe crane functions. When one of the solenoids isenergized, it shifts the valve spool. This allows oilto flow out one of the valve ports. If a functiondoes not work, a directional valve may be toblame.These valves have a standard manualoverride. You may manually shift the valve bypushing the pin, located in the middle of thesolenoid.


CAUTIONMANUALLY OVERRIDING A DIRECTIONAL VALVEWILL PORT OIL IMMEDIATELY TO THE VALVEFUNCTION. THIS WILL CAUSE A SUDDENMOVEMENT OF THE ACTUATOR. OPERATORS ANDMAINTENANCE PERSONNEL MUST KEEP THEWORK AREA CLEAR OF OTHER PERSONNEL WHENOVERRIDING A DIRECTIONAL VALVE.

If the valve shifts using manual overrides,the problem is of an electrical nature. Valvecoils are interchangeable and may bechanged by removing the coil nut. Thisallows maintenance personnel to isolateindividual coil failures. If the valve cannotbe actuated manually or electrically, it isnecessary to replace the section.

INTRODUCTIONTo understand how the relay board operates, it isnecessary to understand how the individualrelays function.

The Bosch relay (part number 77041251) is anormally open relay between terminals 30 and 87and normally closed between terminals 30 and87a. Terminals 85 and 86 energize the relaythrough the coil. See Figure 1 and 2.

Figure 3 shows the relay board with eight relaysidentified with the letters “A” through “G” and bytheir basic function. Example: Relay “A” is the“Power ON/OFF” relay, “C” is the “CompressorSpeed Control”, etc. The small numbers shownon the individual terminals of the relay indicatewhere that terminal is connected through thecircuit board, to the terminal bar. Example: Relay“A” top terminal (#9) is connected to terminal 9 ofthe terminal bar. The terminal bar is provided with16 individual terminals of which the last two (15and 16) are not used. Wires connected to theterminal bar have been identified according totheir function in the circuit. The number ofterminals used vary with each application. Solidlines between relay terminals indicate existingwiring connections, through the circuit board.

RELAY BOARD OPERATIONThe relay board is primarily used on vehicles withremote controlled cranes and remote controlcranes and compressors. The circuitry preventsremote starting of the truck engine unless thebrakes are applied and the PTO is engaged. Italso isolates the crane speed control from thecompressor speed control.

OPERATION

IGNITION “ON”When the ignition switch of the vehicle is turned“ON”, terminal 9 of the terminal bar is “HOT”. Thecoil of relay “A” is energized and voltage fromterminal 1 of the terminal bar becomes present atterminals “A” of relays “A”, “B”, “E” and “H”. SeeFigure 3.

REMOTE STARTING THE VEHICLEThe vehicle can be remotely started from theremote control handle by toggling the “Crane-OFF-Compressor” switch to the “Crane” position.

To start the vehicle, the engine start switch at thehandle must be depressed. When this isaccomplished, terminal 11 of the terminal blockbecomes “HOT”. See Figure 5.

The truck starter is energized when terminals 11and 12 of the terminal bar are connected throughthe relay board. When terminal 11 is “HOT”, thecoil in relay “F” is energized connecting relayterminal 12 and “B” on relays “F” and “G”. Ifterminal 14 of relay “H” and terminal 13 of relay“G” are grounded (brakes and PTO engaged)terminals “B” of relays “F” and “G” are “HOT”.Since terminal “B” of relay “F” is “HOT”, the truckstarter solenoid is activated. Energized circuitsare shown as bold in Figure 5.

REMOTE ENGINE STOPWhen the engine stop button is depressed on theremote control handle, voltage is applied toterminal 6 of the terminal block and of relay “D”.The coil in relay “D” is energized and the groundof the fuel solenoid/distributor coil is interruptedbecause current can no longer flow from terminal7 to 8. Relay “D” is normally closed betweenterminals 7 and 8. See Figure 3.

FIGURE 2. INTERNAL WIRING

FIGURE 1. BOTTOM VIEW OF RELAY


FIGURE 3. RELAY BOARD - COMPONENTS & WIRING


REMOTE ENGINE SPEED (FROM CRANE)Engine speed can be controlled from the remotecontrol handle. When the engine speed switch isactivated, voltage is applied at terminal 10 of relay“E”. The coil of relay “E” is energized and currentis allowed to flow to the signal input of the speedcontrol currently installed. The speed of theengine will remain higher as long as the enginespeed switch in the remote control handle isallowed to remain in the same position. If thisswitch is returned to its original position, theengine speed control coil will be de-energizedthrough relay “E”.

FIGURE 4. REMOTE CONTROL HANDLE

Compressor operation will begin when the“Compressor-OFF-Crane” switch on the handsetis toggled to the “Compressor” position. At thattime, the power from the handset will providepower to the pressure switch on the compressor.When the pressure switch signals a need formore air pressure, the switch will trip and providea signal to terminal 5 of the relay board.

Relay “C” energizes the coil in the relay,connecting terminal 4 to terminal “C” of the relaywhich is “HOT” from relay “B”. Reference Figure6 showing circuits energized (in bold) whenengine speed is increased by the compressor.This will provide a “HOT” signal at terminal 4which then provides a 12-volt signal to input of thespeed control currently installed.

INSTALLATION1. Locate an area in the engine compartment that willboth provide some protection against damage andaccessibility for wiring.

2. Provide adequate space between the mountingsurface and the back of the circuit board in order toprevent electrical contact. Failure to do so will causeerratic operation and/or circuit board failure.

3. Connect control wiring as indicated in Wiring Chart.

4. Jumper wires connections:

4-1. Jumper wires must connect J to K, and L to M for12 volts excited systems. Remove the connecting wiresbetween I to J and M to N.

4-2. Jumper wires must connect I to J, and M to N forground excited systems*. Remove the connecting wiresbetween J to K and L to M.

WARNINGFailure to remove the extra connecting wire will cause the relayboard to fail. Check jumper wire connections of relay board beingreplaced. (Most relay boards are wired as stated in item 4-1.)

* NOTESCircuits that could be ground excited are 6 - 10 & 11.Quick Check: (Before connecting wires to circuit board)Activate the engine stop switch from the crane. If terminal 6 ishot, wire per 4-1. If not, wire per 4-2.

NOTES


Excessive Load Limit System (ELLS) TEST PROCEDURE

This procedure is to be used for testing the Excessive Load Limit System (ELLS) used on the IMT Tele-scoping Crane models. Following this test procedure will ensure the system is currently operable and willnot allow the crane to be excessively overloaded.

The purpose of the ELLS is to prohibit the excessive overloading of the crane. It does this by disarming thefunctions that make it possible for the operator to apply greater than allowable stress to the crane structureand components. The functions which are involved in the ELLS may vary for each crane model (Refer toTABLE 1 for which functions are shut down by the ELLS on each crane).

The load rating of the crane is determined by the pressure induced in the lower boom cylinder. The ELLSsenses the pressure in the base end of the lower boom cylinder with a normally closed pressure switchlocated on the valve block on the top of the cylinder. When the pressure in the base end of the cylinderexceeds the setting of the pressure switch for that particular crane, the pressure switch opens and breaksthe ground connection for the solenoids that shift the valve spool on the appropriate functions. Once theground connection is disengaged, the solenoids that shift the valve spools for the appropriate functions cannot be activated using the remote control handle. Only those functions that will not increase the load mo-ment of the crane structure and components will be operable (i.e.- winch down, extension in, lower boomup, rotation). The operator is able to use “WINCH DOWN” to set the weight down to relieve the crane and“EXTENSION IN” to bring the load in for a shorter load radius. Either of these two functions will decreasethe load moment of the crane structure and components, thus decreasing the pressure in the main cylinder.

C. Test System1. Start truck engine.2. Raise boom up until boom cylinder is fully extended, then lower boom until cylinder is fully retracted

to remove air that may have been introduced while installing the gage.3. Raise boom to 15 degrees above horizontal and securely fasten crane hook to immovable object

using a double line attachment.4. Use the winch up function to take slack out of cable.5. Refer to TABLE 1 for maximum pressure at which ELLS system should shut down appropriate

functions for the particular crane model being tested.6. While monitoring the pressure gage, use the winch up function to slowly apply down force on end of

boom. If the pressure on the gage exceeds the maximum pressure for that particular crane and theELLS has not shut down the appropriate functions, the ELLS is not working. Do not go any higher.

7. If the system is operating properly, the function should stop working before the gage reaches maxi-mum pressure.

8. While the pressure gage still reads the pressure at which the ELLS shut down the appropriatefunctions, test the other functions that should be shut down by the ELLS (TABLE 1).

9. If the appropriate functions are not operational, the ELLS system is working10. If any of the functions in Table 1 are still operational, the ELLS system is not working.11. Refer to the TROUBLE SHOOTING PROCEDURE (page 6) for instructions to determine the

problem with the ELLS.

ELLS TROUBLESHOOTING PROCEDUREEach function (winch up, winch down, extension in, etc.) is actuated by a solenoid that shifts the valvespool to perform the particular function. The solenoids are located on the valve bank. Each solenoid has twowires protruding with a connector on the end that is plugged into a connector on the wire harness for thecrane. There are two wires, one wire is black (ground) and the other wire is colored. The “ground receptacle”is the receptacle that the black wire connects to.

A. Find which solenoid actuates which function-When a solenoid is actuated, it becomes magnetic. By using a piece of steel to find which solenoid ismagnetic, (steel ruler, paper clip, etc.) the solenoids can be matched with which function it controls. Itwill not be a real strong magnetic pull, but will be detectable with a small piece of metal.1. Be sure the truck ignition is on, the parking brake is engaged, and power is “on” to the crane. The

PTO does not need to be engaged.2. Activate “LOWER UP” on the remote control handle and use the piece of steel to find which solenoid

is magnetic (being actuated).3. When the correct solenoid is found, unplug the connector protruding from the solenoid.4. Activate “WINCH UP” on the remote control handle and use the piece of steel to find which solenoid

is magnetic (being actuated).5. When the correct solenoid is found, unplug the connector protruding from the solenoid.6. Unplug the connector protruding from the pressure switch (Some models may have wire terminals

instead of a connection. Detach the wires from the pressure switch.)

7. Using a multi-meter, check continuity (setting on multi-meter that “beeps” if two wires are connected)between the ground receptacle on the connector that plugs into the connector on the “LOWER UP”solenoid and the ground receptacle on the connector that plugs into the connector that plugs into theconnector on the “WINCH UP” solenoid. They should not be continuous. If they are, the harness isthe problem, which needs to be either repaired or replaced.

8. Reconnect the pressure switch.9. Repeat steps 4-8 for each of the functions shut down by the ELLS. Instead of using “WINCH UP”,

use the appropriate function and find the controlling solenoid and check for continuity with groundreceptacle on the connector that plugs into the connector on the “LOWER UP” solenoid.

10. Activate “WINCH UP” on the remote control handle and use the piece of steel to find which solenoidis magnetic (being actuated).

11. When the correct solenoid is found, unplug the connector protruding from the solenoid.12. Unplug the connector protruding from the pressure switch (Some models may have wire terminals

instead of a connection. In this case, detach the wires and use the ground wire that attaches to thepressure switch for the next step.)

13. Using a multi-meter, check continuity between the ground receptacle on the connector that plugsinto connector on the pressure switch and the ground receptacle on the connector that plugs into theconnector on the “WINCH UP” solenoid. They should be continuous. If they are not, there is aproblem with the harness, which either needs to be repaired or replaced.

14. Reconnect the pressure switch.15. Repeat steps 10-14 for each of the functions shut down by the ELLS. Instead of using “WINCH UP”,

use the appropriate function and find the corresponding solenoid. Each one should be continuouswith the ground receptacle on the connector that plugs into the connector on the pressure switch.

16. If there is no problem found with the harness, the pressure switch is the problem and it will need tobe replaced.

INSTALLATION OF AUXILIARY CHASSIS GROUND CABLEKIT (51716427)Due to the increased use of electrical components installed on IMTproducts, we have instituted the practice of installing an auxiliaryground cable between the chassis frame and battery groundterminal, to assist the electrical system of both IMT product andchassis. If your equipment does not include the cable, consideradding the ground cable for added assistance.Install the auxiliary ground cable as follows:

1. Connect one end of cable to chassis frame using 3/8” x 1-1/2”bolt, 5/16” flat washer, 3/8” lock washer, and 3/8” hex nut. SeeNote.

2. Connect the remaining end of the cable to the ground terminalof the chassis battery or to the engine block. See Note.

NOTEGround connections made to metal surfaces shall maintaincontact integrity when subjected to the normal effects of aging,temperature cycling, moisture, splash, spray washing, fatigue,and other environmental conditions. Metal surfaces shall be freeof primer, paint, rust, and corrosion, and have a bright, polishedappearance immediately before the ground terminal is connected.A steel flat washer, with an outside diameter approximately equalto the ring terminal diameter, shall be placed between bolt headand terminal. Grounding studs and joints shall be dedicated to theground and not be used as a structural joint.

WIRE ROPE INSPECTIONWire rope with any of the deficiencies shown below shall beremoved and replaced immediately.

A. Corrosion can be cause for replacement. Anydevelopment of corrosion must be noted andmonitored closely.

B. When there are either 3 broken wires in one strandor a total of six broken wires in all strands in any onerope lay.

C. When flat spots on the outer wires appear and thoseoutside wires are less than 2/3 the thickness of theunworn outer wire.

D. When there is a decrease of diameter indicating acore failure.

E. When kinking, crushing, birdcaging or otherdistortion occurs.

F. When there is noticeable heat damage(discoloration) of the rope by any means.

G. When the diameter is reduced from nominal size by1/32" or more.

H. If a broken wire protrudes or loops out from the coreof the rope.

HOOK INSPECTIONHooks having any of the listed deficiencies shall beremoved from service unless a qualified person approvestheir continued use and initiates corrective action. Hooksapproved for continued use shall be subjected to periodicinspection.

A. DISTORTIONBending / TwistingA bend or twist exceeding 10° from the plane of theunbent hook.

Increased Throat OpeningHOOK WITHOUT LATCH: An increase in throatopening exceeding 15% (Or as recommended by themanufacturer)

HOOK WITH LATCH: An increase of the dimensionbetween a fully-opened latch and the tip section of thehook exceeding 8% (Or as recommended by themanufacturer)

B. WEARIf wear exceeds 10% of the original sectionaldimension. (Or as recommended by the manufacturer)

C. CRACKS, NICKS, GOUGESRepair of cracks, nicks, and gouges shall be carried outby a designated person by grinding longitudinally,following the contour of the hook, provided that nodimension is reduced more than 10% of its originalvalue. (Or as recommended by the manufacturer) (Aqualified person may authorize continued use if thereduced area is not critical.)

D. LATCHEngagement, Damage & MalfunctionIf a latch becomes inoperative because of wear ordeformation, and is required for the service involved, itshall be replaced or repaired before the hook is putback into service. If the latch fails to fully close thethroat opening, the hook shall be removed from serviceor “moused” until repairs are made.

E. HOOK ATTACHMENTS & SECURING MEANSIf any indication of distortion, wear, cracks, nicks orgouges are present, unless a qualified personauthorizes their use. (Or as recommended by themanufacturer)

HOLDING VALVE INSPECTIONThe cylinders are equipped with holding valves that preventsudden movement of the cylinder rods in the event of ahydraulic hose or other hydraulic component failure. Thevalve is checked in the following manner:

1. With a full rated load, extend the cylinder in questionand kill the engine.

2. Operate the control valve to retract the cylinder. If thecylinder “creeps”, replace the holding valve. If thecylinder does not “creep”, the valve is serviceable.

ANTI-TWO BLOCKING DEVICE INSPECTION(See Vol. 1, Operation, Maintenance and Repair for acomplete description)The anti two block system should be checked daily asfollows:

1. Examine flexible rod and weight to insure freeunrestricted mechanical operation

2. Examine cord for damage, cuts or breaks. Grasp cordand pull to check operation of cord reel. The cord shouldretract on reel when released.

3. Start vehicle, engage PTO and slowly winch loadlineup until anti-two block weight comes in contact with thehook end of the loadline cable. At the moment the weightis fully supported, a marked difference in winch operationshould be noted. At this point, the winch up functionshould become very sluggish or non-functioning andhave very little pull capability. Slowly increase truckengine speed while simultaneously actuating the winchup function. The winch characteristics should remainsluggish with little or no tensioning of the cable. Ifoperation other than as described occurs, stopimmediately and investigate. Failure to do so will riskdamage to the cable or the crane.If all is well at this point,actuate the boom extend function slowly, and graduallyincrease to full actuation. Once again the function shouldbe sluggish or non-existent with no tightening of thewinch cable. If operation other than described occurs,stop immediately and reverse the function.

The final check involves actuating both the winch up andextend functions together and checking for properoperation of the anti two blocking circuit. Once again,start slowly and stop if it appears the cable is beingtensioned.

If the anti two block function appears to be functioningnormally, winch the cable down until the sensing weightswings free.

When using the torque data in the charts above, the following rulesshould be observed.

1. Bolt manufacturer’s particular specifications should beconsulted when provided.2. Flat washers of equal strength must be used.3. All torque measurements are given in foot-pounds. Toconvert to inch-pounds, multiply by 12.4. Torque values specified are for bolts with residual oils or nospecial lubricants applied. If special lubricants of high stressability, such as Never-Seez compound graphite and oil,molybdenum disulphite, collodial copper or white lead areapplied, multiply the torque values in the charts by the factor .90.The use of Loctite does not affect the torque values listedabove.5. Torque values for socket-head capscrews are the same asfor Grade 8 capscrews.

WARNINGAnytime a gear-bearing bolt is removed, it must be replaced with anew bolt of the identical grade and size. Once a bolt has beentorqued to 75% of its proof load and then removed, the torquecoefficient may no longer be the same as when the bolt was newthus giving indeterminate clamp loads after torquing. Failure toreplace gear-bearing bolts may result in bolt failure due to metalfatique causing serious injury or DEATH.

TIGHTENING PROCEDURE:1. Refer to the Torque Data Chart to determine the proper torque value to apply to the size of capscrew

used.

2. Follow the tightening sequence shown in the diagram. Note that the quantity of capscrews may differfrom the diagram, but the sequence must follow the criss-cross pattern as shown in the diagram.

3. Torque all capscrews to approximately 40% of the specified torque value, by following the sequence.(EXAMPLE: .40 x 265 FT-LBS = 106 FT-LBS)(EXAMPLE-METRIC: .40 x 36 KG-M = 14.4 KG-M)

4. Repeat Step 3, but torqueing all capscrews to 75% of the specified torque value. Continue to follow thetightening sequence.

(EXAMPLE: .75 x 265 FT-LBS = 199 FT-LBS)(EXAMPLE-METRIC: .75 x 36 KG-M = 27 KG-M)

5. Using the proper sequence, torque all capscrews to the listed torque value as determined from theTorque Data Chart.
