CHAPTER 3 Pronar PT512

3.2.2 LOADING CASE

The loading case of the trailer comprises: the upper frame (1) – figure (3.2) – onto which
a steel floor is welded, the side walls (2), the front wall (3) and the rear wall (4). The side
walls are 600 mm high. As standard, Pronar PT512 trailer is also equipped with profiled
extensions having the height of 800 mm. Optionally additional 600 mm extensions can be
fitted (only in 600 + 600 + 600 version).
The loading case is mounted on brackets of the rear beam and the front crossbar of the lower
frame – see figure (3.1). A tipping direction can be selected by positioning the tipping pins in
the profiled openings. Their construction prevents their inappropriate placing by the trailer
operator.
The rear and side walls of the loading case are secured using pins seated in the front wall
locks and locks welded to rear pillars (5) of the walls. In the lower part they are locked using
hooks located in left and right longitudinal members, as well as in the rear beam of the upper
frame. The walls can be closed and opened by means of two levers (1) – see figure (3.3) –
located on the front beam and, in case of the rear wall, the lever (6) – see figure (3.2) –
located on the left side of the loading case.
The extensions are secured in the same way as the loading case walls. The upper pins of the
extensions are secured in the front extension lock and the rear pillars locks (7). In the lower
part there are hinges (8) welded to the edge of the wall which are used as a closing
mechanism. All hinges are fitted with with cotter pins preventing the pins from falling out.
