DESCRIPTION
The standard body is an all welded construction with all
wear plates fabricated from high hardness
(min. 360 BHN) 10 150 bar (145 000 lbf/in²) yield
strength material. Angled lower body sides reduce
body impacts when loading and a tailshute angle of
25° provides good load retention when travelling
without a tailgate. Refer to Section 000-0000,
GENERAL INFORMATION for body capacities.
The body is pivoted at the rear of the trailer frame and
is operated by two single stage, double acting body
cylinders which are cushioned at both ends of the
stroke to reduce impact shocks. The body cylinders
raise the body to a tipping angle of 65° in
16 seconds and powerdown the body in 12 seconds.
OPERATION
A body control joystick, mounted on the right hand
dash panel, actuates the body control valve by means
of electrical signals to the solenoid valves, which in
turn operate the body hoist cylinders. The four
operating positions of the joystick from front to rear are
as follows:
'FLOAT' - The joystick should be moved to this
position while the body is lowering by gravity and
should remain in this position until the body must be
operated again. The control joystick should always be
kept in 'FLOAT' while the machine is in motion.
'LOWER' - Pushing the joystick forward and holding it
in this position provides hydraulic force to power-down
the body. It is needed when the body cannot be
