HOOK BLOCK
Description
A 75 ton (68 metric ton) hook block and a 10 ton (9 metric
ton) top headache ball are available for the crane. The hook
block utilizes a one-piece pivot block and the hook is
equipped with a safety latch. The hook block is the quick
reeve design.
Maintenance
Periodic Maintenance
It is recommended that the hook block and/or headache ball
be inspected every 50 hours. A complete assembly
inspection should be conducted every quarter or 500 hours
in the area of the hook, hex nut, and threaded areas for
corrosion and proper fit. After assembly of the hook, a liberal
coating of multipurpose grease should be applied to the nut
and threaded area by brush or hand to prevent corrosion.
For hook blocks and other load handling devices not
manufactured by Manitowoc Cranes, Inc.; follow the
manufacturer’s inspection and testing recommendations to
assure an adequate preventative maintenance program is
established.
