Ingersoll Rand Electric Chain Hoist ELK50-1NS50 1PH

• To make sure 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 Ingersoll Rand Technical Support Department or distributor. Failure to provide proper lubrication may result in damage to the hoist and/or its associated components.

1) Hook and Suspension Assemblies

1. Lubricate the lower hook and hook latch pivot points. Hook and latch should pivot freely.

2. Use Ingersoll Rand 47580935001 oil.

• The gear compartment is filled with grease at the factory. Replacement of the grease for the life of the hoist is not required.;

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.

Lubricate each link of the load chain weekly. Apply new lubricant over existing layer.

In severe applications or corrosive environments, lubricate more frequently than normal.

Lubricate hook latch pivot point with the same lubricant used on the load chain.

To remove rust or abrasive dust build-up, clean chain with an acid free solvent. After cleaning, lubricate the load chain.

Use Ingersoll Rand 47580935001 oil.
