6-1. GENERAL

The WorkSaver™ 65 is easy to maintain but to

provide for maximum service life from this unit,

a program of periodic checks and maintenance

are necessary. This section describes

lubrication requirements and general

maintenance procedures. See Figure F-1 for a

graphic representation.

6-2. LUBRICATION

Lubrication is critical to the protection of your

crane. It provides for smooth operation and

protection from corrosion/rust. Following are the

areas which will require periodic lubrication.

ROTATION BEARINGS:

The two rotation bearings in the base were

lubricated at assembly. If the crane becomes

difficult to rotate or becomes noisy, inspect the

bearings and grease if necessary.

STANDARD ROTATION LOCKING HANDLE

THREADS:

Apply a light lubricant weekly to the threads to

provide for ease of operation and rust

prevention. Do not over lubricate or get oil on

the handle which could cause the operator to

loose his grip on the handle.

EXTENSION BOOM:

Lightly grease the sides of the extension boom

to provide for easy withdrawal from the lower

boom when adjusting crane reach. An

extension boom which is difficult to slide in and

out can be hazardous.

WIRE ROPE:

Wire rope is lubricated during its manufacture

but this lubrication will not protect the rope for its

service life. It is necessary to lubricate wire

rope in order to prevent corrosion, friction

created heat and to extend its life.

Lubricate the wire rope as follows:

1. Clean the rope of dirt, dust and any other

foreign matter.

2. Apply a light lubricant which will penetrate

the strands of the rope. Apply by dropping on,

Section 6. MAINTENANCE

spraying on or bushing on.

3. Apply lubricant heavily to portions which

encounter bending such as at the sheave and

winch.

6-3. WIRE ROPE REPLACEMENT

Replace the entire wire rope when any of the

following conditions exist:

1. When there are either 3 broken strands or a

total of six broken wires in all strands in any

rope lay.

2. When flat spots on the outer wires appear

and those outside wires are less than 2/3 the

thickness of the unworn outer wire.

3. When there is a decrease of diameter

indicating a core failure.

4. When kinking, crushing, birdcaging or other

distortion occurs.

5. When there is noticable heat damage

(discoloration) of the rope by any means.

6. When the diameter is reduced from nominal

size by 1/32" or more.

7. If a broken wire protrudes or loops out from

the core of the rope.

See the IMT Operator’s Crane Safety Manual

for more information concerning wire rope.
