A diesel engine is housed in a compartment at the rear
of the frame. The engine provides crane mobility, drives
the hydraulic pumps, charges the air system via the
compressor, and drives the alternator.
A 100-gallon (378-liter) capacity fuel tank is mounted on
the left side of the frame between the axles. The filler
cap, located on the side of the tank, is accessible from
The torque converter is mounted on and driven by the
engine. It drives the three-section hydraulic pump, the
converter/transmission charging pump.
The transmission is a powershift six-speed (forward and
reverse) type. The transmission is mounted on the
carrier frame near the center of the crane.
The front and rear axles are drive and steer (axles) with
brakes at all four wheels.
The hydraulic reservoir is located on the right side of the
carrier. The reservoir contains hydraulic system oil and
includes a filter and by-pass valve.
Turntable Assembly and Swing Mechanism
An anti-friction roller bearing supports the superstructure
on the carrier frame allowing 360 degrees continuous
rotation (swing) in either direction. The bearing is driven
arrangement mounted above the bearing in the turntable.
The two-section boom extends from 34.4 to 60.4 feet
(10.52 to 18.46 meters). The boom is mounted on a
turntable and is raised/lowered and extended/retracted
by hydraulic cylinders.
Auxiliary Boom Nose
The auxiliary boom nose consists of a welded extension
with a sheave assembly. The auxiliary boom nose is
mounted on the boom nose. Main Hoist
The main hoist provides power for all load raising and
lowering operations. The main hoist is mounted at the
rear of the boom on the turntable.
The auxiliary hoist provides power for all load raising and
lowering operations when the auxiliary boom nose is
installed and the overall ball is being used. The auxiliary
hoist is mounted on the counterweight.
