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.

Track:

The two rubber tracks are driven indepently of each other. They are each direct drive

requiring less maintenance and service than chain driven machines. Each track is adjusted
automatically using hydraulic pressure. The rubber track allows the machine to attain a high
transportation speed with excellent manouverablility and traction

Hydraulic system:

The diesel engine has the Pump Drive 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.

Track drive:

The closed-loop track drive system includes two speed track drive motors that

are connected to the drive pumps by means of high pressure hydraulic hoses. The hydraulic
motors are mounted to the track drive wheels and mobilize the tracks. Track movement is
controlled by directional control joysticks on the consoles.

Steering system/operator's platform:

The independent hydrostatic travel drives allow

the paver to be turned on the spot. The eletronic synchroisation, controlled from the operating
panel, ensures that the paver runs straight ahead. The operating panels can be secured in
variable positions on both left and right console panels, by a locking mechanism.

Steering is accomplished merely by driving one track at a different speed than the other. If
turning left, the track on the right hand side will move faster than the track on the left. If turning
right, the track on the left hand side will move faster than the track on the right.

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) and are raised hydraulically to empty onto the conveyor
chains. To facilitate the emptying and to improve material transfer, each of the lateral covers
of the hopper are hydraulically moved.

Conveyors (Material transfer):

The paver is equipped with two conveyors driven sepa-

rately with pressure from a single pump. The system consists of a single, pressure compen-
sated, load sense style, variable displacement, open loop pump driving two fixed volume
hydraulic motors. This pump supplies hydraulic power for both conveyors of the machine and
provides power for the cylinders on the machine.

These conveyors transer the material from the hopper to the augers. By using sensors to
monitor the filling height during the paving proceedure, the transfer amount or speed regula-
tion is completely automatic.
