5. LOAD CHAIN REEVING. Make sure welds on standing links are away from load sheave.
Reinstall chain if necessary. Check that the last link of the load chain is securely connected.
Make sure chain is not capsized, twisted or kinked. Adjust as required.
Frequency of periodic inspection primarily depends on the severity of usage:
NORMAL
yearly
Disassembly may be required for HEAVY or SEVERE usage. Keep accumulative written records
of periodic inspections to provide a basis for continuing evaluation. Inspect all items in "Frequent
Inspection." Also inspect the following:
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 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.
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 temperatu res -1° to 49° C (30° to 120° F) use EP 2
grease or equivalent.
