Crane Stowing Operation
Safety Precautions
WARNING! The following safety messages
address a potential Unsafe Operation Hazard
while stowing the crane:
• Do not drag the hook block sideways on the
ground when loosening or stowing the hook
block. This could allow the wire rope cable
to become twisted or wind irregularly onto
the winch drum. The wire rope cable must
wind uniformly onto the winch drum to
prevent damage to the wire rope cable.
• Do not allow the hook block to slew and
interfere with peripheral devices while
stowing the crane. Keep the hook block from
slewing while stowing the crane.
• Do not allow the hook block to contact the
boom while stowing the crane. While
retracting the boom or lowering the boom,
the hook block could contact the boom.
Move the winch lever slowly to prevent the
hook block from contacting the crane while
performing these operations. Damage to the
boom, hook block and/or wire rope cables
may result.
The boom retracting operation will lower the hook
block. The hook block also lowers with the boom
lowering operation. Raise the hook at the same
time so the hook block will not touch the ground or
interfere with the machine.
Stow the boom securely into the STOW position.
After stowing the boom, verify the Boom Stowing
Light on the outrigger display turns green. If the
Boom Stowing Light does not turn on, the
outriggers cannot be stowed. If the Boom Stowing
Light does not turn on, lower the boom to the
maximum or slew the boom to verify the Boom
Stowing Light turns on.
The Hook Stowage Switch cancels the auto-stop
function of the over winding detector.
