Design and operation
3.3 LOAD BOX
The trailer load box (1) is a welded structure
made from steel sheet and shapes. It is
available in three versions, depending on
the direction of unloading the load box:
• left tipping
• right tipping
• left and right tipping.
The trailer has hinged side walls (5) locked
with hydraulically operated lower walls
(4). The load box has a conical shape to
ensure smooth rearward discharge. The
side walls gradually widen towards the
rear, which increases the width by 5 cm.
There is a sight glass in the front wall
covered with a grille and a PLEXI glass
cover.
The load box is seated in the rear beam
sockets and on the brackets welded to the
lower frame in its front part. These sockets
are the pivot point when tilting the box
backwards or to the side. The tipping di-
rection is selected by means of two tipping
pins, the design of which prevents their
inappropriate placement by the trailer
operator.
The trailer can be additionally equipped

with 600 or 800 mm high wall extensions
(2).
In the front part of the trailer there is a doc-
ument tube (10) and the access ladders
(7) and (8) are fixed to the wall and to the
front extensions. On the inside of the wall
and the front wall extension, there are
steps (11) and a folding step (12) to facil-
itate access to the load box.
In the rear part of the load box there is the
tailgate (3) which is opened and closed
using hydraulic cylinders. In order to
enable more precise unloading of loose
materials, a slide gate (12) is located in
the tailgate. As additional equipment of
the trailer, it is possible to mount the rear
chute (13), mounted under the lower edge
of the slide gate.
The trailer can be additionally equipped
with a tarpaulin (9) and a fenced platform
(6) serving as a platform for the operator
handling the tarpaulin.
