SECTION 1
INTRODUCTION
The rough terrain crane incorporates an all welded steel
frame, using planetary drive axles to provide four-wheel
drive. Axle steering is accomplished utilizing hydraulic steer
cylinders. The engine is mounted at the rear of the crane and
provides motive power through a six speed forward and
reverse transmission.
The carrier frame incorporates an integral fifth wheel, to
which the rear axle is mounted, to provide axle oscillation.
Axle oscillation lockout is automatic when the superstructure
rotates from the travel position.
The superstructure is capable of 360° rotation in either
direction. All crane functions are controlled from the fully-
enclosed cab mounted on the superstructure. The crane is
equipped with a five-section, full power, sequenced and
synchronized boom. Additional reach is obtained by utilizing
an optional swingaway boom extension. Lifting is provided
by a main and auxiliary hoist.
