LOAD BLOCK AND HOOK-AND-WEIGHT
BALL INSPECTION Daily Inspection
The operating condition of the load block and the hook-and-
weight ball can change daily with use, and therefore must be
inspected daily (at the start of each shift). During operation,
look for any defects that could affect their safe operation.
Correct all defects before using the load block or the hook-
and-weight ball.
Daily inspection and maintenance will include the following
checks (
Figure 5-51 and Figure 5-52 ):
WARNING
Falling Load Hazard!
To prevent the load from dropping due to structural failure
of load block or hook-and-weight ball:
• Only use a load block or a hook-and-weight ball that
has a capacity equal to or greater than the load to be
handled.
• Do not remove or deface the nameplate ( Figure 5-50 )
that is attached to the load blocks and hook-and-
weight balls.
• See Section 4 of the Operator Manual for
recommended sling angles and capacity restrictions
when the load block has a duplex or a quadruplex
hook.
