10. LOAD CHAIN END ANCHORS. Ensure both ends of load chain are securely attached.
Secure if loose, repair if damaged, replace if missing.
11. LOAD CHAIN. Measure the chain for stretching by measuring across eleven link sections all
along the chain (ref. Dwg. MHTPA0041) paying particular attention to the most reeved links.
When any eleven links in the working length reach or exceed the discard length shown in Table
2, replace the entire chain. Always use a genuine

12. CHAIN CONTAINER. Check for damage or excessive wear and that chain container is
securely attached to the hoist. Secure or replace if necessary.
13. LIMIT ASSEMBLY. Check throttle lever moves freely. To limit hook downward travel the
loop in the slack chain side must contact the throttle lever. To limit hook upward travel the
bottom hook block must contact the throttle lever.
To test “UP” and “DOWN” travel limits first run hoist slowly with no load to verify proper
function. Repeat test at full speed with no load to verify proper function.
Hoists Not in Regular Service
1.
A hoist which has 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 into service.
2.
A hoist that has 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 into
service.
3.
Standby hoists should be inspected at least semiannually in accordance with the requirements
of “Frequent Inspection.” In abnormal operating conditions equipment should be inspected at
shorter intervals.
