4.2 STOWING FLY JIB
Never perform any work riding on the crawler. You might slip and fall causing a serious
accident. To work in a high place, be sure to install a stable work table.
NOTES
When stowing the main boom, retract the main boom fully, then make the fly jib angle to 0 degree and
the number of boom sections to 1 (fully retracted).
When stowing the fly jib mounted on the main boom tip, to the right section of the main boom, follow the
procedure below.
1. Install the outrigger.
For outrigger setup, see “Operation 2.14 Outrigger setting
operation”.
2. Remove the wire rope connected to the single hook,
following the procedure below.
CAUTION
• Be careful not to wind the wire ropes irregularly.
• Do not unwind after the hook block touches the ground,
since the wire ropes are wound irregularly inside the
winch drum when the hook is lowered further to the
ground.
(1) Make the main boom fully retracted and make sure the
main boom angle is approx. 20 degrees.
(2) Operate the winch lever to lower the single hook (10)
so that it is barely touching the ground.
(3) Lower the single hook (10) to the ground by lowering
the boom.
(4) Remove the bolt (50) and the washer (51) and pull out
the wedge socket pin (49) to remove the wedge socket
(37) from the single hook (10).
(5) Remove the wire clip.
(6) Prepare a cylindrical rod (A) of 6 to 8 mm and place it
on the rope wedge (41) and remove the rope wedge
(41) from the wedge socket (37) by tapping the rod
gently with a hammer in the direction of the arrow (a)
and remove the wire rope (12).
(7) Pull out all the wire ropes (12) to the sheave on the
main boom tip.
