M A E D A Crawler Crane 5.4 CRANE OPERATION
5/2020 CC1908S-1 5-29
OPERATION BEFORE
CRANE WORK
WARNING
Extending or raising the boom with the hook
block hung on the wire stowage rope may
break the stowage wire rope and damage the
normal stowage device on the front of the
upper slewing body. Be sure to lower the
hook so that the stowage wire rope does not
become tight.
IMPORTANT
• Be careful not to lower the hook block
excessively so that it falls sideways on the
ground. Doing so results in irregular
winding on the winch drum.
• When the hook block is loosened from the
normal stowage position, the hook block
may sway, interfering with and damaging
surrounding equipment. Pay due attention
to the vicinity of the hook block.
Perform the following operations before crane
work:
1.
Place the lock lever in the free position (F).
2.
Operate the right-hand control lever to the
"Hoist down" side (push forward) to lower
the hook block (1) and loosen the stowage
rope (2) (normal stowage position).
Do not lower the hook block (1)
excessively here.
If it is lowered excessively, the loosened
hook block (1) may damage
surrounding equipment.
3.
Operate the right-hand control lever to the
"Raise" side (pull inside) to raise the boom.
Be careful not to allow the hook block
(1) and stowage rope (2) to become
overtightened here. If the stowage rope
(2) is overtightened, lower the hook
block (1).
4.
Repeat the operations in Steps 2 and 3 and
slowly raise the boom until the hook block
(1) is at the position where it is perpendicular
to the stowage section in the front of the
upper slewing body.
WARNING
If the hook block (4) is removed from the
stowage rope (5) without the boom being
raised to near the stowage position, the hook
block (4) will sway considerably, possibly
damaging surrounding equipment and
resulting in serious personal injury.
