To ensure continued satisfactory operation of the trolley, 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 trolley eight hours each day, five
days per week. If the trolley 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 trolley. Approval for the use
of other lubricants must be obtained from your Ingersoll-Rand
Technical Support Department or distributor. Failure to observe
this precaution may result in damage to the trolley and/or its
associated components.
Hook and Suspension Assemblies
1.
Lubricate the 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 ISO VG220 oil.
Powered Trolleys.
Periodically, grease the trolley wheel and drive pinion gear teeth
with Ingersoll-Rand No. 68 grease or a standard No. 2
multipurpose grease.
Trolley wheel bearings are prepacked with grease and sealed.
Gears
The gear compartment is prepacked with grease at the factory
and has continual lubrication. Replacement of the grease, for the
life of the trolley, should not be required.
The gearbox contains 0.2 pints (1 dl) of gearbox grease
“Blasolube”, a semifluid sodium soap/mineral oil based grease
with a NLGI consistency: “0” (nought). Texaco MARFAK 0
(Texaco product code 0927) is a suitable replacement. Gearbox
grease “Chevron Duralith EP O”, is also suitable (this grease is
also used in the QUANTUM Series hoists).
NOTICE
• Ensure that different base greases (sodium based and
lithium based) are not mixed. The gear box must be emptied
and cleaned when switching types of lubricant.
Make sure that the gear cover is perfectly sealed after any
dismantling.
If it becomes necessary to remove the gear box assembly, first
ensure the trolley assembly is standing on end with the gear box
assembly down. Failure to observe this procedure may allow the
grease to flow from the trolley. Whenever the gear box assembly
is removed, always replace the gasket.
