6.3.3 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.
• Whilst winding the hook to the Fly-jib tip, never use the moment limiter emergency stop cancel
switch to wind the hook up. Excessive force may be applied and damage the Fly-jib. To wind
up the hook, always use the over-winding cancel switch.
To retract the No.2 Fly-jib, follow the instructions below:
1. Keep pressing the over-winding cancel swtich 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).
NOTES
Removed position pin (4) will be necessary for the later
operation to secure the retracted No.2 Fly-jib (3).
3. Keep pressing the over-winding cancel 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.
CAUTION
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 departs from the No.2 Fly-jib
(3).
