1. FASTENERS. Check rivets, capscrews, nuts, cotter pins and other fasteners on hooks,
hoist body and chain bucket, if used. Replace if missing and tighten or secure if loose.
2. ALL COMPONENTS. Inspect for wear, damage, distortion, deformation and cleanliness.
If external evidence indicates the need for additional inspection return the hoist to your
nearest service repair center.
3. HOOKS. Inspect hooks for cracks. Use magnetic particle or dye penetrant to check for
cracks. Inspect hook retaining parts. Tighten or repair, if necessary. Refer to applicable
specifications for additional hook inspection information.
4. CHAIN SHEAVES. Check for damage or excessive wear. If damage or wear is noted,
return the hoist to your nearest service repair center.
5. LOAD CHAIN. Measure the chain for stretching by measuring across five link sections
all along the chain (ref. Dwg. C-01). When any five links in the working length reach or
exceed the discard length shown in Table, replace the entire chain. Always use a
genuine AMH replacement chain.
6. BRAKES. Raise a load equal to the rated capacity of the hoist a few centimeters
(inches) off the floor. Verify hoist holds the load without drift. If drift occurs, contact your
nearest service repair center for repair information.
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.
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 to 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 to 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.
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
