Raise Mast Using Boom as Holdback
Circled numbers in Figure 4-12 match the following steps.
1. Start crane engine.
2. Attach assist crane to boom hoist equalizer (View D):
a. Attach 4-leg chain sling to lifting holes in equalizer.
b. Securely attach wire rope slings between equalizer
and rotating bed or carbody of assist crane.
3. Remove boom hoist equalizer retaining pins (View B)
from mast top forks.
4. Store equalizer retaining pins (View C) in mast top lugs
(View C).
5. Lift boom hoist equalizer and pull equalizer off forks on
end of mast. Pay out boom hoist wire rope as required.
6. Park assist crane so equalizer is centered with relation
to mast to prevent side loading mast.
7. Tie a 50 ft (15 m) long tagline to end of each
counterweight strap nearest crane.
8. Using crane setup remote control, fully lower live mast
arms.
9. Verify that all mast strap and counterweight strap
shipping pins are removed and stored.
.
10. Perform Mast Pre-Raising Steps before proceeding.
11. Slowly haul in mast hoist wire rope to raise mast until
straps are taut.
12. Continue to raise live mast while paying out boom hoist
wire rope.
NOTE Operator shall match rate of speed at which mast
hoist wire rope is hauled in with rate of speed at
which boom hoist wire rope is paid out. Boom hoist
wire rope must remain slack until mast nears
vertical.
Watch mast stops as mast rises. If necessary,
guide mast stops clear of live mast.
13. Stop raising mast when it is at 65° maximum (View E).
When fixed mast is at 65°, live mast will be at
approximately 75°. The live mast angle can be
monitored on the display in the cab.
14. Place equalizer to side so it will not interfere with
assembly of boom. Take necessary precaution to
prevent damage to boom hoist wire rope.
Turn Drum 5 PARK ON to engage drum pawl.
15. Install desired length of boom. See Install Boom topic in
this section for instructions.
Minimum boom length of 137.8 ft (42 m) is required
16. Continue to raise mast while paying out boom hoist wire
rope.
17. As mast nears vertical, tighten boom hoist wire rope as
required so mast moves smoothly past vertical to rear.
NOTE Use taglines to guide counterweight straps clear of
mast stops and live mast as fixed mast lowers.
18. Continue to slowly haul in mast hoist wire rope and pay
out boom hoist wire rope to lower mast to rear.
19. Stop lowering mast when mast stops engage mast stop
pins on rotating bed.
NOTE The MAX-ER mast stop position information
screen will not be available with crane software
version M002066 or newer.
20. While watching indicator rod on mast stops (View F) or
mast stop information screen on main display (View G),
mast up slowly until:
• Indicator rods are flush with ends of indicator tubes
• Indicator arrow (on display) is in line with green line
CAUTION
Wire Rope Damage!
Boom hoist equalizer will tip if it is not properly supported,
possibly resulting in damage to wire rope. Support boom
hoist equalizer properly while raising fixed mast.
WARNING
Mast Damage!
Lower live mast arms before raising fixed mast. Mast can
collapse if arms are up when live mast is lowered.
CAUTION
Mast Damage!
Avoid mast or equalizer damage. Do not raise mast until
all straps are unpinned from mast strap supports.
CAUTION
Structural Damage!
Do not raise mast until boom hoist equalizer is unpinned
from rails and boom straps are unpinned from strap
supports.
