Engine:
The paver is powered by a 6-cylinder, water cooled diesel engine with direct injec-
tion and a turbo charger. Electric starting and belt driven alternator battery charrging is stan-
dard. The engine power / rpm is controlled by the engine speed control on either of the
consoles. The engine is shut down either by removing the key “ON/OFF” switch or he emer-
gency stop switch. For further details, see the technical data in the engine’s instruction man-
ual.
Running gear: The paver is rear wheel, hydraulically driven and uses the hydraulics
on the second front wheels to assist with the steering. The steering wheel sends the
signal to the front tandem pivoting axle to turn. Once the front tandem pivoting axle
starts to turn, a signal is sent to the rear wheels requiring one wheel to use more flow
that the other to turn the machine. So as the front wheels receive the signal to turn
left, a signal is sent to the right rear wheel to use more power to turn that wheel faster
than the wheel on the left and the second front wheels assists hydraulically with the
turn . As the front wheels receive the signal to turn right, a signal is sent to the left rear
wheel to use more power to turn the wheel faster than the wheel on the right and the second front wheels
assist hydraulically with the turn.
As a result of this, the steering capability and the load capacity are improved, espe-
cially on soft ground. The paver is mounted with flexible solid tires on the front wheels
and large-size, tubeless, air filled tires on the rear wheels.
Hydraulic system:
The diesel engine has the distribution gear box attached to it. This
drives the hydraulic pumps for all of the main and auxilary paver functions. The hydraulic sys-
tem also drives the generator needed to heat materials to prevent the material from sticking
to the screed plate. All power on the paver comes from hydraulics.
Propel drive:
The closed-loop propel drive system includes two speed track drive motors
that are connected to the drive pumps by means of high pressure hydraulic hoses. The hy-
draulic motors are mounted to the rear drive wheels which move the paver. Forward and re-
verse movement is controlled by directional control joysticks on the consoles while the
variable speed, independent drive wheels are controlled by a steering wheel on either of the
operator consoles.
Steering system/operator’s platform:
The independent hydrostatic travel drives allow
the paver to be turned in a small radius. The eletronic synchronization, controlled from the
operating panel, ensures that the paver runs straight ahead. The operating panel can be se-
cured in a position on the left-hand or the right-hand side of the paver by means of a latch
assembly.
Steering is accomplished by using the tandem steering axel in front of the machine. The
steering axel is controlled by the steering wheel at the opertor’s console. Rotate the steering
wheel clockwise to turn the machine right. Ratate the steering wheel counter-clockwise to
turn the machine left.
Push roller crossbar:
The push rollers for material trucks are connected to a crossbar that
pivots at its center. This crossbar allows for differences in distances to the rear wheels on a
variety of material trucks. This permits the paver to deviate less from its course and makes
paving curves easier.
Material compartment (hopper):
The hopper inlet is equipped with a conveyor system
that empties the hopper and transfers the material to the auger. The hopper can hold approx-
imately 30,000 lbs. (13608 kg). To facilitate the emptying and to improve material transfer,
each of the lateral covers of the hopper are hydraulically moved.
