Section 4. OPERATION

4-1. GENERAL

This section describes set-up, general operation

and storage procedures. It is the operator’s

responsibility to familiarize himself with these

procedures and conform to safety standards as

specified in the IMT Operator’s Crane Safety

Manual and any Federal, State or local codes.

4-2. INSPECTION

An inspection of the crane and vehicle should

be performed daily, before the crane is used.

Visually inspect the crane for:

•

STRUCTURAL DAMAGE

• LOOSE PARTS

• MOUNTING BOLT TIGHTNESS

• HOOK DEFORMATION/CRACKS

• WIRE ROPE DEFORMATIONS

• ELECTRICAL SYSTEM MOISTURE

• PROPER ELECTRICAL CONTACTS

• PROPER LUBRICATION

• SHEAVES & DRUM FOR CRACKS/WEAR

Visually inspect the vehicle for:

•

UNDER-INFLATED TIRES

• WORN/UNSAFE TIRES

• BROKEN SPRINGS/SUSPENSION

• FULLY CHARGED BATTERY

• SECURE PARKING BRAKE

Any defects found or suspected should be

reported and corrected immediately.

4-3. JOB SET-UP

Before operation, position the crane so the load

can be handled easily without obstructions and

within specified range of crane. The vehicle

must be parked on a firm, level surface.

WARNING

THE PRESENCE OF ANY ELECTRICALY

CHARGED POERLINES IS TO BE AVOIDED.

FAILURE TO DO SO WILL RESULT IN SERIOUS

INJURY OR DEATH. CONSULT THE IMT

OPERATOR’S CRANE SAFETY MANUAL FOR

FURTHER INFORMATION.

Engage the emergency brake, turn the ignition

OFF and place the transmission in PARK (on

automatic transmissions).

With the vehicle secured, extend the outriggers

so they are positioned on a firm surface and

locked into position.

Remove the control handle/cable from its

storage container and plug it into the receptacle

at the left side of the lower boom.

WARNING

DO NOT ALLOW PERSONNEL WITHING 10 FEET

OF ANY PORTION OF AN OPERATING CRANE.

Turn rotation locking handle on mast

counterclockwise to release tension on base.

Manually rotate crane to a position where the

boom can be manipulated and tighten locking

handle by turning clockwise. On the optional

power swing model, rotate the crane by using

the appropriate switch on the remote control

handle.

Position the boom at either of its positions above

horizontal. Physically lift the boom and insert

the quick release pin into position (20°, 40° or

60°) as shown in Figure D-2 or D-3.

To extend the boom, unwind a few feet of cable

from the winch and pull the extension boom out

to line-up the desired extension boom pin hole

with that in the lower boom. Insert the extension

boom pin.

WARNING

DO NOT PULL EXTENSION BOOM COMPLETELY

OUT OF LOWER BOOM AS IT CAN CAUSE

SERIOUS PERSONAL INJURY IF DROPPED.

The crane is now in the work position.

4-4. PERFORMING A LIFT

First, know the weight of the load being lifted

and that that load is within the capacity of the

crane.

WARNING

NEVER EXCEED THE CRANE’S RATED LOAD

CAPACITIES. DOING SO WILL CAUSE

STRUCTURAL DAMAGE AND DAMAGE TO THE

WINCH AND CABLE WHICH CAN LEAD TO

SERIOUS INJURIES OR DEATH.

Position the hook block directly over the load by

rotating the crane. Lower the hook block by

pressing the control switch DOWN until the

hook can be attached to a sling or other suitable

handling device which is securely attached to

the load. The sling must be captivated by the

safety latch. See Figure D-1.

WARNING

DO NOT WRAP THE WINCH WIRE ROPE AROUND

THE LOAD. THIS WILL DAMAGE AND WEAKEN

THE WIRE ROPE, MAKING IT EXTREMELY

DANGEROUS.
