4. When the hole of the inner rod (6) for 0 degree angled Fly-jib
and the hole of the outer rod (5) match, insert the position pin (7)
to the holes and insert the linchpin (25). When inserted, ensure
the ring is turned to lock it.
5. Remove the lever block (23).
[Posture of the 0 degree angled Fly-jib]
The posture in the figure in the right shows
that the Fly-jib is configured to 0 degree tilt
angle from the stowage position in
accordance with the procedure 1 to 4, as
above. Once configured to this posture, the
0 degree tilt angle data is transmitted to the
moment limiter, then the moment limiter
display indicates the angle of the Fly-jib, and
the rated total load is also computed.
[Posture of the 60 degrees angled Fly-jib]
The posture in the figure below right shows that the Fly-jib is configured to 60 degrees tilt angle
from [Posture of the 0 degree angled Fly-jib] as above. Once configured to this posture, the 60
degrees tilt angle data is transmitted to the moment limiter, then the moment limiter display
indicates the angle of the Fly-jib, and the rated total load is also computed.
To change the Fly-jib tilt angle to 60 degrees:
(1) Continue the boom derricking operation and the procedure specified in 3. above (un-winding
the lever block) alternately to allow the Fly-jib angle to be gradually adjusted.
(2) Match the hole of the outer rod and the the hole of the inner rod for 60 degrees angled Fly-jib.
(3) When the hole of the inner rod (6) for 60 degrees angled Fly-jib and the hole of the outer rod
(5) match, insert the position pin (7) to the holes and insert the linchpin (25). When inserted,
ensure the ring is turned to lock it.
• To change the Fly-jib tilt angle to 40 degrees, practice similarly as above to obtain the Fly-jib
tilt angle of 40 degrees.
• To change the Fly-jib tilt angle to 20 degrees, use only the lever block function to obtain the
Fly-jib tilt angle of 20 degrees.
