CAUTIONS WHEN SLINGING
• Check the following before hoisting a load.
Attempt to hoist the load without checking may result in serious accidents by dropping the load or
tripping.
• Observe the values in the rated total load chart.
• Hoist from the centre of gravity of the load.
• Check that the wire rope of the hook block is vertical.
• When the load leaves the ground, stop winding up the load once and check whether the load is
stable.
• Before hoisting a slung load, always check whether the sling wire rope “retainer device” of the hook
block is hung correctly. If the “retainer device” is not hung, the wire rope may leave the hook block and
cause the load to fall resulting in a serious accident.
• Larger wire rope angle when hoisting the load increases force that applies to the wire rope even when
the load weight is unchanged, thus may cause the wire rope to snip. Give due consideration to slinging
operation so that excessive force is not applied to the wire rope.
• Hoist only 1 load at a time.
Attempts to hoist more than one load may cause the hoist bracket to hit and damage the other hoisted
load, or the loads move and lose balance, causing serious accidents such as tripping.
Do not hoist more than 1 load at a time even if the total combined weight is within the rated total load.
• Hoisting of lengthy load causes the load to lose balance and is dangerous.
In the case of such load, hoist vertically by using a cramp, or achieve balance of the hoisted load by
applying a rope to both ends of the load.
CAUTIONS WHEN HANDLING WIRE ROPE
• Wire ropes can wear out from constant use or old age, so be sure
to inspect every time before work, and replace immediately if at or
beyond the replacement standard.
At the same time, inspect the sheave at the tip of the boom and
the sheave of the hook block. Damaged sheaves accelerate the
damage of the wire ropes.
• Use wire ropes specified by us.
• The operator may be injured by breaking wire strands.
• Always wear leather gloves when handling the wire rope.
• Do not use a wire rope of which any of the following applies:
• 10% or more of strands (except a filler wire) in 1 twist of a wire
rope are snipped.
• The wire rope diameter abrasion is beyond 7% of the nominal
diameter.
• Kinked wire rope.
• Excessively deformed or corroded wire rope.
• Affected by heat or sparks.
