Considered as the multi-talent in the JOSKIN range, the Drakkar is a multipurpose trailer for the transport of many different types of material: silage, grains, pulp, beets, potatoes, etc. Thanks to its unique and very fast unloading system, with a hermetic conveyor belt and a moving front wall, the material avoids being damaged, while the body is perfectly stable during the use. Its low weight is due to the synthetic side walls (UV-resistant Carbofont), which allows to transport a maximal payload. Furthermore, its running gear ensures a perfectly stable driving performance, whatever the terrain type.
The Drakkar has an industrial hermetic conveyor belt that moves the material during the unloading operation. This high-resistance conveyor belt is rolled up on a cylinder driven by 2 hydraulic engines at the back of the tapered trailer body (+ 4 cm at the front). During unloading, the front wall, together with the conveyor belt, moves backwards to accompany the material without compressing it. At the end of the operation, it can have a pushing effect resulting in compact and firm heaps, if the user wishes to. The transparent perspex plate (10 mm thick) on the front wall 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 with a yaw chain. This revolutionary system therefore allows a safe unloading without tipping, even in sheds or low places, without compressing the transported material (therefore no shocks or bruising on the transported products). The emptying speed of the Drakkar is optimised to less than 2 minutes with any type of product. At the end of the emptying process, the driver only makes the conveyor belt go one meter back while closing the door, before returning to the field. With a simple impulse, the conveyor belt will return automatically to the front position to receive a new load.
The trailer is unloaded easily and without blocking thanks to the significant clearance (60 cm) of the rear door (operated by two double-acting rams) above the body. A locking device on the hydraulic ram makes sure the door is perfectly closed and avoids any unexpected opening during transportation. A "stop" sensor on the door allows the conveyor belt to start moving only when the door is fully open. In some situations, it is possible to leave the door closed to empty through the standard grain chutes (3 grain chutes of 60 x 27 cm) or to only slightly open it. To that end, there are two control boxes at the back of the vehicle to progressively make the conveyor belt move forward or backward. A thick seal of industrial quality is fitted around the back of the Drakkar to provide a perfect tightness.
The rear (upper and lower) scrapers remove any remaining material on the moving floor. The one at the front prevents foreign material to accumulate between the floor and the conveyor belt. Large side scrapers ensure that the body is tight for all types of products.
All Drakkar are standard equipped with a drawbar suspension. On double-axle models, it is a mechanical one with a bundle of cross leaves between the drawbar and the chassis to perfectly absorb shocks or movements. On triple-axle models, the suspension is ensured by two double-acting hydraulic rams with one large-capacity nitrogen accumulator. Nothing is more comfortable! Furthermore, the control box in the cab allows to modify the body slope. It is therefore ideal for your works on headlands, to go on heaps or simply to transfer extra weight to the rear axle of the tractor, especially in difficult harvesting conditions. All double-axle Drakkar are standard equipped with a bolted Roll-Over running gear. This concept, which is characterised, among other things, by parabolic suspension leaves underneath the axle square, guarantees an upward traction line and therefore a perfect traction ease. The triple-axle Drakkar are equipped as standard with a Hydro-Tridem running gear, with a 24-cm clearance and a perfect load distribution for a maximum stability.
All Drakkar are standard fitted with various pieces of pre-equipment to easily add various options, either at the time of the order or later (even years after the purchase). Among the most interesting options, you can find: Duo-Cover nets or hermetic covers, hydraulic extensions, transfer augers, hydraulic drop sides, plus many more!
