CRANE INSTALLATION
In addition to meeting Minimum Chassis
Specifications, there must be sufficient room
for mounting the crane and the platform must
be strong enough to support the crane and
rated load. Install the crane only on an IMT
designed and approved truck body. The body
must be designed to sustain the forces
imposed by the crane when lifting the full rated
load. In addition, an IMT designed body is
designed to take full advantage of the standard
reservoir placement. This reservoir is in-
stalled in the cargo area of the body. Before
attempting to install the crane, the body must
be installed.
To install the crane:
1. Use a lifting device capable of lifting the
weight of the crane. See Specifications Sec-
tion for crane weight. Attach fabric slings to
the crane lower boom, centered approximately
18 inches from the mast hinge. Make certain
the crane is well balanced on the slings by
slowly lifting approximately 6" off the ground.
Lift the crane, apply a bead of waterproof
compound, such as silicon based caulk, to the
bottom of the base. Move the chassis under
the crane and lower the crane into the desired
position.
2. Install the 1-8x3" mounting cap screws
(use Permanent Thread Lock) and 1" washers
to secure the crane base to the truck body
(see Crane Installation drawing). Torque the
cap screws to 680 ft-lbs (94 kg-m).
