7. SUPPORTING STRUCTURE. If a permanent structure is used inspect for continued ability to support
load.
8. LABELS AND TAGS. Check for presence and legibility. Replace if necessary.
9. END ANCHOR. Ensure end anchor on hoist is installed and unbent. Repair if damaged, replace if
missing.
Hoists not in Regular Service
1. Hoists which have been idle for a period of one month or more, but less than one year should be given
an inspection conforming with the requirements of "Frequent Inspection" before being placed in
service.
2. Hoists which have been idle for a period of more than one year should be given a complete inspection
conforming with the requirements of "Periodic Inspection" before being placed in service.
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.
Maintenance
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 anti-seize compound and/or thread lubricant on cap screw 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.
Lubrication
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.
Load Chain
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 dust build-up, clean chain with acid free solvent. After cleaning, lubricate the chain
with a SAE 50 to 90 EP oil.
