DESCRIPTION
Front frame (1)
The front frame
is
a weldment, and it contains a fuel tank. A plastic water tank (14) is placed
in
the front part of the frame
along with a hydraulic oil tank (13) and a storage battery (20) with a master switch. The driving unit is flexibly mounted
in
the rear part of the frame. The whole space of the front frame is covered with a hinged laminated cowl.
Rear frame (2)
The rear frame is a weldment too. The platform (15) and plastic water tank (14) are flexibly mounted
on
the frame. The
protective frame (21)
is
fixed to the rear part of the frame.
Articulated joint (3)
The hinge joins the front and rear frames. It has a horizontal pin (1) and a vertical pin (2). Both are mounted
in
bearings
that make it possible for both parts to turn horizontally as well
as
vertically.
Front and rear forks (4)
The forks attach the drums flexibly to the rear and front frames. The travel hydraulic motor is fixed to the left fork; the
absorber plate with two rubberized metal pieces
is
also flexibly attached to the right fork
Front and rear drums (5)
The drum is welded of steel plates.
In
the lids there are roller bearings with the shaft of the vibrator with two eccenters.
The shaft
is
driven through a clutch by the vibration hydraulic motor. The bearings are lubricated by a grease fill. The
drum rotates
in
the bearing
in
the right lid and the bearing of the hydraulic motor.
Driving unit
This unit
is
flexibly mounted
in
the front frame. It consists of a combustion engine with air cooling (6) which
is
driven by
the travel hydraulic generator via the clutch. Two gear hydraulic generators - vibration and servosteering (8) - are
mounted
on
the engine side.
