Two seats
fitted with safety belts
are installed in the cabin
.
The driver’s seat is spring-
supported, adjustable depending on driver’s weight and height as well as by the angle of
back inclination in the longitudinal direction, it has convenient fold-back arm rests.
Steering column
with integrated instrument panel can be adjusted by tilt: rated tilt of the
column is 25° towards horizon. The steering column tilt is adjustable by 2° in forward direc-
tion and by 21° in backward direction against the rated angle.
Tilt angle shall be fixed using the handle located at the
left side of the column.
It is possible to install steering column with steering
wheel adjustment by height.
The
pneumatic system
is
three-circuit, ensuring braking of the tractor front and rear axle
wheels as well as trailer wheels.
The system provides for simultaneous operation of the brake drives of the front and rear trac-
tor wheels, the energy accumulator drive, the parking brake, air extraction for tyre pumping
and at tractor towing, blowing off air cleaner cassettes and the entire tractor. In addition, the
equipment for trailer brake control is installed on the tractor, which serves both for reducing
speed of the trailer as a part of the road-train and for its automatic braking in case of a break
of the coupling with the hauler.
In the brake pneumatic drive system there are three mutually independent circuits, e.g. in
case of failure of one circuit, the remaining ones will keep functioning. The circuit independ-
ence is provided by installation of a triple protection valve 3 into the mainline downstream of
the pressure controller 1, which ensures the “cut-off” of the failed circuit from serviceable
ones. In doing so, the serviceable circuits will keep functioning and will provide for tractor
braking.
