Lubrication
Routine Lubrication Requirements

Lack of or an excessive amount of lubrication will affect the 
performance and life of this tool Use only recommended 
lubricants at below time intervals:

EVERY 8 HOURS OF TOOL OPERATION

 -fill lubricator 

reservoir with spindle oil (29665). If an in line or air line 
lubricator is not used, fill oil reservoir of built-in oiler of hoist 
head.

EVERY 80 HOURS OF HOIST OPERATION

 - Grease fittings 

in lower BLOCK HOOK ASSEMBLY and TROLLEY 
WHEELS with NLGI #1 grease 33153).

EVERY 160 HOURS OF HOIST OPERATION

 - Fill oil 

reservoir in GEAR CHAMBER with “EP” gear oil (40164). 
Coat load chain of hoist with EP” gear oil (40164).

Air Supply Requirements

For maximum operating efficiency, the following air supply 
specifications should be maintained to this hoist.:

AIR PRESSURE - 90 PSIG (6 bar)

AIR FILTRATION - 50 micron

LUBRICATED AIR SUPPLY

HOSE SIZE - l/2” (13 mm) I.D.

An AR0 model 128241-800 airline FILTER/REGULATOR/
LUBRICATOR (F-R-L) is recommended to maintain the 
above air supply specifications.

Recommended Lubricants

After disassembly is complete all parts, except sealed or 
shielded bearings, should be washed with solvent. To 
relubricate parts, or for routine lubrication, use the following 
recommended lubricants:

Operation
Suspending Hoist Adjusting Brake

Always select an overhead support capable of supporting 
combined weight of hoist, trolley, and hoist’s load capacity.

Hook Suspended Models

Upper hook should be firmly seated in center of hook 
saddle and that safety latch is closed.

43059 secondary support cable is recommended.

(Dwg.               )

Trolley Suspended Models

Be sure TROLLEY WHEELS are compatible with beam 
being used.

Width between outside of TROLLEY WHEELS should be 
the width of beam  l/2”.

If 43111 - 90’ ADAPTER is used, mount to hoist before 
attempting to install trolley.

Width is varied by using SPACERS between the hoist 
body and the trolley SIDE PLATES.

Insert an equal number of SPACERS on each inside of 
the trolley SIDE PLATES until beam  l/2” 
measurement is reached. SIDE PLATES must be 
vertical.

Insert SHAFTS (43009) through hoist, or adapter if used, 
and trolley SIDE PLATES.

Position trolley and hoist assembly on beam.

Put an equal number of SPACERS on each end of 
SHAFTS (43009) with lock washer being last.

Tighten nuts on SHAFTS (43009). SHAFTS should 
extend all the way through the NUTS.

Move trolley over entire length of beam. If it appears the 
trolley SIDE PLATES can be moved closer together and 
freedom of movement will be maintained, remove an 
equal number of SPACERS from inside the SIDE 
PLATES and assemble these SPACERS to the outside of 
the SIDE PLATES.

Tighten NUTS to 25-30 ft. Ibs.

Connect sufficient length of air hose to reach the 
maximum travel distance of trolley.
