4.3.3 RETRACTING OF No.2 FLY-JIB
When the Fly-jib angle is set higher, No.2 Fly-
jib may rapidly slide out when the position pin
which fixes it is extracted, which may cause a serious accident
resulting in death or serious
injury. Before you extract the position pin, always wind up the hook close to the Fly-jib tip to
prevent No.2 Fly-jib from rushing out. In such events, be careful to avoid your hand or part of
your body being caught between the No.2 Fly-jib tip and the hook.
To retract the No.2 Fly-jib, follow the instructions below:
1. Keep pressing the hook stowage switch
and wind up the hook
(10) slowly, until it lightly touches the No.2 Fly-jib (3) tip.
2. Pull the linchpin (25) out from the position pin (4) in the tip of
No.1 Fly-jib (2) to extract the position pin (4).
Removed position pin (4) will be necessary for the later
operation to secure the retracted No.2 Fly-jib (3).
3. Keep pressing the hook stowage switch and continue the
hook winding up operation and the boom lowering operation
alternately, so that the No.2 Fly-jib (3) is slowly retracted.
When the hook is wound up, No.2 Fly-jib (3) is retracted by
the force of the winch. During such practices, the Fly-jib
No.2 (3) may not be smoothly drawn in due to it’s angle.
In such an event, lower the boom or take hold of handles
on the both left and right side at the tip of No.2 Fly-jib (3)
and push No.2 Fly-jib (3) in.
4. When No.2 Fly-jib (3) is retracted, adjust both side holes of
No.1 Fly-jib (2) and No.2 Fly-jib (3) to insert the position pin (4).
Apply the linchpin (25) to secure the position pin.
5. Un-wind the hook down so that it separates from the No.2
Fly-jib (3).
