17. Lay the load line back in the boom tip sheaves and insert both retainer pins & cotters.
18. Replace all of the pins in their lugs for storage and insert their haipin cotters.
19. Install the sheave block on the load line, if desired.
20. Check the Anti-Two-Block system for proper operation, and set Rated Capacity Limiter
configuration.
SETTING THE OFFSET ANGLE ON THE OFFSETTABLE BOOM EXTENSION:
1. The boom extension must be installed on the main boom tip and the load line, downhaul
weight and wedge socket installed on the boom extension and secured with all of the
retainer pins.
2. Draw the load line taut with the hoist by pulling the downhaul weight against the bottom of
the tip sheave plates while holding the anti-two-block override switch under the control
panel.
WARNING
Be careful not to operate the TELESCOPE lever while overriding the
anti-two-block system. This may break the load line and allow the boom
extension and downhaul weight to fall, causing death or serious injury
to personnel.
3. Remove the offset index pin from the boom extension knuckle. To loosen the pin it may
be necessary to rock the boom extension tip up and down manually while maintaining the
proper tension in the load line.
4. Lower or raise the load line with the hoist until the 0, 15, or 30 degree offset holes align in
the knuckle.
5. Insert the index pin in the knuckle and retain it with the hairpin cotter.
6. Set Rated Capacity Limiter configuration.
STOWING THE BOOM EXTENSION
:
1. If the boom extension is offset to 15 or 30 degrees, return it to the zero offset position as
described above.
2. Perform steps 16-20 of the boom extension installation and stowing procedure.
3. Set Rated Capacity Limiter configuration.
