16000 HANGING MAX-ER® OPERATOR MANUAL SET-UP AND INSTALLATION
Disconnect Beam from Crane — SEQUENCE 2
See Figure 4-34 for the following procedure.
1. Position boom at an angle that causes counterweight
tray to land firmly on ground (View D).
2. Lower beam support (1, View D) to assembly position:
a. Using hand winch (2, View A), rotate handle until
lifting cable (3) is taut and pins (4, View C) 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 (4, View C) from stored position.
c. Using hand winch, lower beam support to assembly
position and install pins (4, View C).
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 the 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. Using remote control switch (on beam assembly),
fully extend hanging counterweight lifting cylinder to
slacken counterweight links and straps.
c. Mast up (Drum 4) to lower fixed mast to desired
position.
d. Fasten a 50 ft (15 m) long tagline to each
counterweight strap (5).
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.
e. Remove pins (7, View E) to disconnect links (6) from
links (8).
f. If necessary, guide straps to vertical with taglines.
g. Reinstall pins (7) in links (6) for storage.
h. 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. Attach lifting slings (9, View D) from assist crane to front
lifting lugs on beam assembly (10).
7. Lift beam assembly with assist crane until pins (12, View
B) are loose.
8. Remove pins (12, View B).
9. Travel 16000 away from hanging counterweight
assembly.
10. Lower beam assembly onto beam support.
11. Disconnect lifting slings from beam assembly.
NOTE The hanging counterweight assembly can be
stored in this position or disassembled.
12. Store pins (12, View B) in beam assembly or in beam
insert (11).
