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 transfer 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.
Augers: The augers are driven and controlled independently from the conveyors.
The auger hydraulics consist of two high pressure, variable displacement, closed loop
pumps driving two fixed volume motors. The left-hand and the right-hand half of the
auger can be controlled separately.
The conveying direction can be changed towards the center or the outside ensuring
that there is always a sufficient supply of material even if an excessive amount of ma-
terial is required at one side. The auger speed is controlled by sensors that monitor
the material flow leaving the conveyor.
Height adjustment and extension of augers:
Height adjustment and extension of
augers ensure an optimum variety of a wide range of paving thicknesses and widths.
Auger height is regulated at the operating panel and moved by means of hydraulic
cylinders.
Auger segments of different lengths can be attached to easily adapt to the different
paving widths.
Levelling/slope control system (option):
The slope control system allows the pav-
ing thickness to be regulated at the left-hand or the right-hand side with a defined dif-
ference to the opposite side.
To determine the actual value, the two screed lifting arms are linked with a slope con-
trol rod.
The slope control system always operates in conjunction with the screed height ad-
justment of the opposite side.
By adjusting the height of the screed lifing arms, the paving thickness of the material
or the laying height of the screed can be controlled.
Activation occurs electro-hydraulically on both sides and can be controlled manually
by means of toggle switches or automatically by means of an electronic grade control
system.
Screed lifting arms: The screed lifting arms are used to lift the screed during trans-
portation. Lifting occurs electro-hydraulically on both sides by actuating the hydraulic
cylinders on the screed lifting arms and is controlled by means of toggle switches on
the operating panel.
Truck hitch (option): The truck hitch holds the transport vehicle for paving material
in contact with the paver. They are located on the front of the hopper.
