Engine:
The paver is powered by a 6-cylinder, water cooled diesel engine with direct injection and a
turbo charger. Electric starting and belt driven alternator battery charging is standard. 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 the emergency stop switch. For further details,
see the technical data in the engine’s instruction manual.
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 maneuverability and traction.
Hydraulic system: The diesel engine has the Pump Drive gear box attached to it. This drives the
hydraulic pumps for all the main and auxiliary paver functions. The hydraulic system 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 electronic synchronization, 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 one 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 approximately 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 separately with
pressure from a single pump. The system consists of a single, pressure compensated, 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 transfer the material from the hopper to the augers. By using sensors to monitor the
