Raise Mast
Circled numbers in Figure 4-30 match the following steps.
1. Start crane engine and select/confirm SETUP mode.
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 at Dimension A from
end of crawlers (see View A, and Table 4-4
). Equalizer
must be centered with relation to mast to prevent
side loading mast.
Assist crane must provide specified holdback
forces (B and C, View A and Table 4-4
).
7. Using remote control, fully lower live mast arms.
8. Verify that all mast strap shipping pins are removed and
stored (Figure 4-29
, View C).
9. Perform mast pre-raising steps before continuing.
10. Slowly haul in mast hoist wire rope to raise mast until
straps are taut.
11. If boom will be used as a holdback, proceed as follows.
Otherwise, go to step 12.
a. Haul in mast hoist wire rope and pay out boom hoist
wire rope to raise mast.
b. Keep boom hoist rope as slack as possible to
prevent boom hoist wire rope from bearing
against rope guard in mast top (View G).
c. Do not raise mast any higher than 65°.
When fixed mast is at 65°, live mast will be at
approximately 53°. The live mast angle can be
monitored on the display in the cab.
d. Turn on drum park for Drums 4 and 5.
e. Place boom hoist equalizer on ground to side of
boom assembly area and disconnect assist crane.
Take every precaution to protect wire rope from
damage.
Do not allow wire rope to jump off sheaves (in
mast and equalizer) or otherwise become
fouled.
f. Refer to Boom Installation in this manual and
completely install desired length of boom and jib, if
equipped.
g. Turn off drum park for Drums 4 and 5 and go to step
12.
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 during mast raising.
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 proceed to raise
mast until fixed mast straps are unpinned from strap
brackets.
WARNING
Mast Damage!
Mast raising cylinders must be lowered using set-up
remote before lifting loads with fixed mast.
