Ingersoll Rand MLK Serie Manual De Instalación Y Operación página 14

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. Also, the lubricant types and
change intervals 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. Failure to observe this precaution may result in damage to the hoist and/or its associated
components.
General Lubrication Information
The top and bottom hooks are supported by thrust bearings. These bearings require to be packed with
a standard No. 2 multipurpose grease at regular intervals. Neglect of proper lubrication will lead to
bearing failure. Contact your nearest Ingersoll-Rand service repair center for aditional information.
•
Do not use automotive type detergent oil. Detergents will delaminate the motor vanes in
MLK and HLK hoists and cause premature failure.
Air Line Lubricator
Lubricate the hoist supply air with SAE 30W non-detergent motor oil (minimum viscosity 135 Cst
at 40° C (104° F)) from an in-line lubricator. The use of detergent oil may cause premature failure.
Load Chain
•
Failure to maintain 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 environment, lubricate more frequently than normal.
3. Lubricate hook and hook latch pivot points with the same lubricant used on the load chain.
4. To remove rust or abrasive dust buildup, clean chain with acid free solvent. After cleaning,
lubricate the chain.
5. Use Ingersoll-Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP oil.
Hook and Suspension Assemblies
1. Lubricate the hook and hook latch pivot points. Hook and latch should swivel/pivot freely.
2. Use Ingersoll-Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP oil.
3. On HL4500K and HL6000K hoists Lubricate the Idler wheel bearings in the upper suspension
housing and bottom hook assembly with Ingersoll-Rand No. 68 Grease or a good quality No.
2 multipurpose grease.
4. On HL4500K and HL6000K hoists after each 300 hours of operation or more frequently if hoist
is operating in a contaminated atmosphere, inject 2 or 3 shots of grease from a grease gun into
grease fittings in the end of the idler wheel shafts.
