CHAPTER 3 Pronar T400

3.3 LOADING PLATFORM

The load box consists of welded elements that are connected with each other by bolts. The
front wall of the trailer is made as a welded structure made of steel profiles and sections. In
its upper part there is an openable tilting extension (3). It is used to load materials using a
combine harvester or forage harvester by reducing the height of the front wall.
The side walls are made of two longitudinal beams to which the side posts are bolted. This
construction is in whole covered with perforated steel sheet riveted to the bearing elements.
Both side walls are connected with each other by screwed crossbars on the bottom, while at
the top with two tightening strings (7).
Floor conveyor track guides (4) are bolted to the crossbars of the lower side walls. The
mechanism is driven by hydraulic motors and is intended for unloading. The gear chains slide
in the guide troughs, the scraper bars (5) are attached to the chains. A detailed description of
the installation can be found in chapter 3.5 FLOOR CONVEYOR MECHANISM HYDRAULIC
SYSTEM.
The floor (6) of the Pronar T400 trailer is made of boards laid and bolted to the lower
crossbars of the load box. The boards are arranged tightly next to each other, each
subsequent board is shifted towards the neighbor by half the length. The side surfaces of the
boards are connected by means of a tongue and a groove.
The rear part of the loading box has a hinged tailgate. It is made as a welded structure made
of profiled sheet and steel profiles. The tailgate is raised by means of two hydraulic cylinders
located on both sides of the box. A detailed description of the hydraulic installations can be
found in chapter - 3.4 TAILGATE HYDRAULIC SYSTEM.
In the rear part of the load box it is possible to install dosing drums to facilitate precise
unloading of the trailer. The drums come in two variants, drums for green fodder and drums
for corn chaff. The structure and operation of this mechanism is described in chapter (3.9)
DOSING DRUMS WITH POWER TRANSMISSION SYSTEM.
