3.2.2 LOAD BOX
Trailer's load box consists of: upper frame (1) – figure (3.2) with welded steel floor, side walls
(2), front wall (3) and rear wall (4). Side walls are 600 mm high. As standard, Pronar PT510
trailer is also equipped with 600 mm-high wall extensions made of profiled steel sheet;
additional 600 mm-high middle wall extensions are also available to obtain the total wall
height of 600 + 600 + 600mm. Additional middle extensions are available as optional
equipment.
The load box is mounted on sockets of the rear beam and front crossbar of the lower frame -
compare with figure (3.1). The chosen tipping direction is achieved by positioning the pin in
the appropriately profiled socket opening, the construction of which prevents their
inappropriate placing by trailer operator.
Load box rear and side walls are secured using pins in front side locks and locks welded to
rear stakes (5) of side housing. In the lower part they are locked using bolting hooks placed
in the left and right longitudinal beam and also in the rear upper frame beam. Closing and
opening the walls is performed using two levers (1) - figure (3.3), placed on the front beam
and in the case of the rear wall, using a lever (6) – figure (3.2), placed on the left side of the
load box.
Extensions are secured in the same way as the load box walls. Upper pins of the wall
extensions are secured in the front extension locks and locks of rear stakes (7). In the lower
part the closure is formed by hinges (8) welded to the side wall edge. All hinges are equipped
with pins with cotter pins preventing them from falling out.
