2. HOOKS. Check for wear or damage, increased throat width, bent shank or twisting of hook.
Replace hooks which exceed the throat opening discard width shown in Table 1 (ref. Dwg.
MHTPA0040) or exceed a 10° twist (ref. Dwg. MHTPA0111). If the hook latch snaps past the
tip of the hook, the hook is sprung and must be replaced. Check hook support bearings for
lubrication or damage. Make sure they swivel easily and smoothly. Repair or lubricate as
necessary.
3. UPPER AND LOWER LIMIT DEVICE. Test operation with no load slowly to both extremes
of travel. Upward travel must stop when the bottom block or stop buffer on chain hits hoist limit
arm. Downward travel must stop when the loop at the unloaded end of the chain decreases and
activates the limit arm.
4. AIR SYSTEM. Visually inspect all connections, fittings, hoses and components for indication
of air leaks. Repair any leaks found. Check and clean filters if equipped.
5. CONTROLS. During operation of hoist, verify response to pendant is quick and smooth. Ensure
the controls return to neutral when released. If hoist responds slowly or movement is
unsatisfactory, do not operate hoist until all deficiencies have been corrected.
6. HOOK LATCH. Check operation of the hook latch. Replace if broken or missing.
•
Do not use hoist if hook latch is missing or damaged.
