4.6 UNLOADING
The trailer is equipped with a hydraulic
tipping system, and a suitable frame and
load box construction enabling tipping
to the sides and to the rear. Tipping the
load box is controlled by means of the dis-
tributor of the tractor's external hydraulic
system.
The trailer is unloaded in the following
order:
• the tractor and trailer should be
placed for straight driving on level,
hard and level ground,
• Block the tractor and trailer with
parking brake,
• tipping pins (1), (2) (connecting the
load box to the lower frame) should
be placed on the side on which the
unloading will be carried out and
properly secured - fi gure (4.8).
• tipping pins and individual seats are
designed in such a way that they
cannot be moved diagonally across
the load box, which would cause
damage to the trailer,
• open appropriate wall closures and
/ or extensions, or open the chute
slide in the rear wall (depending on
the intended direction and method of
unloading),
Use caution when opening, as
the load can put a lot of pressure
on the walls.
When opening wall closures do
not stand in the area of the wall
to be opened and the load being
unloaded
