The JOSKIN DRAKKAR is a multi-purpose trailer allowing to transport many different types of material (silage, grains, pulp, beets, potatoes, etc.). Thanks to the UV-resistant polyester/polyethylene side walls, the empty weight of the vehicle is lower. You can therefore transport a higher payload.
The side and rear walls of our silage trailers and multi-purpose trailers are profiled in the unloading direction of the silage matter (maize, grass,...) so as to unload while limiting friction strains. They are indeed 5 cm wider at the back.
As a result, it is quick and easy to unload them without blockage, either with a hydraulic drive or a mechanical one with P.T.O.-shafts (option).
Width + 5 cm
The trailer is unloaded easily and without blocking thanks to the significant clearance (40 cm) of the rear door operated by two double-acting rams above the body.
A locking device mounted on the ram makes sure the door is properly closed and avoids any unexpected opening during transportation.
A "stop" sensor on the door allows the floor to start moving only when the door is fully open.
In some situations, it is necessary to leave the door closed to empty through the grain chute(s) or to only slightly open it. To that end, there are two control boxes at the back of the vehicle that allows to progressively make the floor move forward or backward.
The DRAKKAR has an industrial fluid-tight conveyor belt that is going, for the unloading operation, to transport the material. This high-resistance conveyor is rolled up on a cylinder driven by 2 hydraulic engines at the back of the trailer.
During the unloading operation, the front wall, which is connected to the moving floor, is going to support the material without compressing it. At the end of the operation, it is going to have a pushing effect resulting in compact and firm heaps. The use of a transparent perspex plate (10 mm thick) ensures an excellent visibility when loading and unloading.
The floor and the wall resume their initial positions thanks to a hydraulic engine at the front of the trailer, which is connected to a system of shipping chains.
The rear (upper and lower) scrapers allow to remove any remaining material on the moving floor. The one at the front prevents foreign bodies to accumulate between the bottom and the moving floor.
