Disconnect Beam from Crane — SEQUENCE 1
See Figure 4-27 for the following procedure.
1. Lower beam support (8, View D) to assembly position:
a. Using hand winch (9, View A), rotate handle until
lifting cable (10) is taut and pins (11, View G) are
loose.
NOTE The hand winch has an automatic brake which
applies to hold the beam support in position when
you stop turning the handle.
b. Remove pins (11, View G) from stored position.
c. Using hand winch, lower beam support to assembly
position and install pins (11, View G).
2. Using remote control switch (on beam assembly), fully
extend hanging counterweight lifting cylinder to lower
beam support (8) onto ground and to slacken
counterweight links and straps.
3. Disconnect counterweight straps (View E):
NOTE The fixed mast can be lowered approximately 4° so
counterweight straps are vertical or as close to
vertical as possible during following steps.
Watch mast stop information screen on main
display (View G, Figure 4-11
) while lowering mast.
System fault alert will come on and mast hoist will
be inoperable when screen reads 0.15 ft (0,046 m).
NOTE The MAX-ER mast stop position information
screen will not be available with crane software
version M002066 or newer. The MAX-ER mast
stop limit switch will trigger crane fault #27 as the
mast retracts the cylinders to 80% or beyond. See
Section 3 Mast Stop Limit Switch procedure.
a. Position boom at mid-range of “Liftcrane Boom with
Mast” capacity chart or boom down as you lower
mast.
Do not allow boom to bottom out against boom
stops.
b. Mast up (Drum 4) to lower fixed mast to desired
position.
c. Fasten a 50 ft (15 m) long tagline to each
counterweight strap (12).
NOTE If counterweight straps are not hanging vertical,
tighten taglines to support straps so they cannot
swing freely when pins are removed in next step.
d. Remove pins (14, View E) to disconnect links (13)
from links (15).
e. If necessary, guide straps to vertical with taglines.
f. Reinstall pins (14) in links (13) for storage.
g. Mast down to raise mast back to proper position
shown in View G, Figure 4-11
.
If boom is on ground, it will be necessary to boom up
during this step to properly position mast.
4. Fully retract hanging counterweight lifting cylinder.
5. Disconnect hydraulic lines and electric cable from rear of
crane and store on beam assembly. See Figure 4-28
.
• Thoroughly clean hose ends and couplers and
install protective caps.
• Thoroughly clean cable ends and install protective
caps.
6. Connect lifting slings from assist crane to proper lifting
lugs on beam assembly (see Figure 4-25
).
7. Lift beam assembly with assist crane so beam support is
just clear of ground.
8. Store beam support:
a. Remove pins (11, View G) from assembly position.
b. Using hand winch (9, View A), raise beam support
to stored position and install pins (11, View G).
9. Remove pins (7, View C) connecting beam assembly (1)
or beam insert (2) to rear of crane.
10. Lift beam assembly clear of crane.
11. Remove ladder (3, View F) from slots (6) on right side of
beam assembly.
12. Place beam assembly on ground as shown in View F,
Figure 4-25
).
13. Disconnect lifting slings and remove assist crane.
14. Store pins (7) in beam assembly (1) or beam insert (2).
15. Store ladder (3, View B).
