2250 OPERATOR MANUAL SETUP AND INSTALLATION

ELEVATED CAB ASSEMBLY (35-FOOT
TOWER)
General
This section provides assembly and removal instructions for
the elevated cab option.
The elevated cab must be installed and removed by
experienced personnel trained in the erection of construction
cranes. These personnel shall read and become thoroughly
familiar with the instructions section and in the Operator
Manual supplied with the crane before attempting to install or
remove the cab tower.
The installation and removal area must be firm, level, and
free of ground and overhead obstructions. The area selected
must be large enough to accommodate the 2250 and cab
tower in addition to the movement of an assist crane required
to install and remove the parts.
Safety
The crane rotating bed must be properly supported before
beginning the installation of the elevated cab. The method of
support varies, depending on the application for which the
crane was designed.
Some parts of the crane and cab tower cannot be reached
from the ground. Take necessary precautions to prevent
falling off the crane and cab tower during assembly and
disassembly.
Installing Elevated Cab
Attaching Cab Tower to Crane
See Figure 4-23
for the following procedure.
NOTE: Lift on the chords, not the ladder or tower
cross members.
1. Using slings, shackles, and other rigging as needed, lift
the tower from the trailer.
2. Align the tower base with the mounting plate on the
rotating bed (see View B).
3. Insert and retain the pins (see View B).
4. Lower the tower top onto the blocking 1016 m (40 in)
minimum (see View A).
5. Bolt the support first to the tower chord and then to the
deck (see View A).
NOTE: For the first installation, align the support with the
deck and drill holes in the deck to match the
location of the bolt holes in the support.
6. Using slings and shackles attached to the cross beam
(see View A), slowly raise the cab tower to the working
position, allowing it to pivot on the pins.
7. As the cab tower nears vertical, allow the tower to rest
on the cab base mounting plate and align the bolt holes
(see View D).
8. Bolt the tower to the mounting plate (see View D).
9. Stiffen the tower with the turnbuckles (see View C).
a. Slide the turnbuckle support over the vertical pin
mounted on the rotating bed.
b. Pin the turnbuckle to the lugs on the turnbuckle
support and the tower.
c. Tighten the turnbuckles evenly to stiffen the tower.
