LUBRICATION

To ensure continued satisfactory operation of the hoist, all 
points requiring lubrication must be serviced with the correct 
lubricant at the proper time interval as indicated for each 
assembly. Correct lubrication is one of the most important 
factors in maintaining efficient operation.

The lubrication intervals recommended in this manual are 
based on intermittent operation of the hoist eight hours each 
day, five days per week. If the hoist is operated almost 
continuously or more than the eight hours each day, more 
frequent lubrication will be required. The lubricant types are 
based on operation in an environment relatively free of dust, 
moisture, and corrosive fumes. Use only those lubricants 
recommended. Other lubricants may affect the performance 
of the hoist. Approval for the use of other lubricants must be 
obtained from your

 Technical Support 

Department or distributor. Failure to provide proper 
lubrication may result in damage to the hoist and/or its 
associated components.

Hook and Suspension Assemblies

1. Lubricate the lower hook and hook latch pivot points. 

Hook and latch should pivot freely.

2. Use 

Ingersoll Rand

 LUBRI-LINK-GREEN or a SAE 50 to 

90 EP oil.

Load Chain

WARNING

• Failure to maintain a clean and well lubricated load 
chain will result in rapid load chain wear that can lead to 
chain failure which can cause severe injury, death or 
substantial property damage.

1. Lubricate each link of the load chain weekly. Apply new 

lubricant over existing layer.

2. In severe applications or corrosive environments, 

lubricate more frequently than normal.

3. Lubricate hook latch pivot point with the same lubricant 

used on the load chain.

4. To remove rust or abrasive dust build-up, clean chain with 

an acid free solvent. After cleaning, lubricate the load 
chain.

5. Use 

Ingersoll Rand

 LUBRI-LINK-GREEN or a SAE 50 to 

90 EP oil.

„

Gears

The gear compartment is filled with grease at the factory to 
provide continual lubrication. Replacement of the grease for 
the life of the hoist should not be required.

„

Lubrication Grease:

Strub N1424
Type DIN 51502: GP OM-20

„

Lubrication Grease Quantity:

If it becomes necessary to remove the gear end cover, first 
ensure the hoist body is standing on end with the gear end 
cover up. Failure to observe this procedure will allow the 
grease to flow from the hoist. Whenever the gear end cover 
is removed, always replace the cover gasket.

CAUTION

• Use extreme care when removing gear end cover to 
avoid grease spillage.
