3. Standby hoists should be inspected at least semi-annually in accordance with the requirements of
"Frequent Inspection." In abnormal operating conditions equipment should be inspected at shorter
intervals.
1. Proper use, inspections and maintenance will increase the life and usefulness of your AMH
equipment.
2. Never perform maintenance while supporting a load.
3. During assembly lubricate gears, nuts, bolts and all machined threads with applicable lubricants.
Use of antiseize compound and/or thread lubricant on capscrew and nut threaded areas prevents
corrosion and allows for ease of disassembly of component.
4. Hand Chain Adjustment or replacement. (Refer to Dwg. C-02 and C-03) When cutting the weld
side of a hand chain link, do not cut or nick the opposite side. A damaged link must be replaced to
prevent premature failure. A falling hand chain can injure personnel.
•
To create a "C" link, cut the welded side of the link with a hack saw. (Refer to Dwg. C-02)
Clamp one side of the "C" link in a vise and bend it open by using pliers to grip the exposed
part of the link. (Refer to Dwg. C-03)
•
If you are replacing the hand chain, disconnect it at the "C" link. Cut a length of chain 2 times
the required drop plus 1 foot (30 cm). To prevent a twist maintain an even number of links.
Run the chain around the hand wheel. Connect the hand chain ends with bent open "C" link
then bend shut.
•
Make sure the hand chain is not twisted. To untwist, open the "C" link and remove one link.
5. Test before returning the product to service after performing any maintenance.
General
The use of thread lubricant or anti-seize compound is recommended for threaded components. Unless
otherwise stated, remove old lubricant, clean the part with an acid free solvent and apply a new coating
of lubricant to the part before assembly.
Gears
Unscrew nuts on the opposite side of the hoist as the hand chain, and remove gear cover and support
plate. Remove old grease and replace with new. For temperatures -29° to 10° C (-20° to 50° F) use EP
1 grease or equivalent. For temperatures -1° to 49° C (30° to 120° F) use EP 2 grease or equivalent.
Trolley
•
Wheel bearings are sealed and require no lubrication. If trolley wheel rotation is rough or noisy,
replace trolley wheel bearing.
•
Geared Trolley Pinion Shaft pinion should be lubricated before installing in side plate with EP 2
grease.
•
Geared Trolley Wheels require EP 2 grease Brushed on exposed wheel and pinion teeth. Apply
as necessary to keep teeth covered. If the grease becomes contaminated clean and brush on
new.
Load Chain
1. Lubricate each link of the load chain weekly with a SAE 50 to 90 EP oil. 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 build-up, clean chain with acid free solvent. After cleaning, lubricate
the chain.
