Tipping

The tipping system is standard oil fed. There is an option that makes it possible to replace it by a hydraulic pump, which may be fitted with a hydraulic or electric lowering control.

Door: tight and safe

Monocoque tipping trailers are fitted with very resistant synthetic rubber seals all around the body. The door is kept closed by a side locking device (except on vehicles with drop sides).

This system allows a perfect tightness of the JOSKIN tipping trailers, even with small grains.

The doors of the JOSKIN tipping trailers are fitted with two safety devices:
- In order to prevent system damage, a pressure relief valve regulates the oil pressure if the door cannot be completely closed, e.g. due to an obstacle;
- A safety valve on each door ram holds the door in position if hydraulic hoses break or if the tractor stops.

Safe Tipping

The position of the tipping ram on the front part of the chassis allows to reduce the stresses to the body and makes the vehicle as stable as possible.

Standard mounted on all models of the JOSKIN tipping trailer range, the safety valve, which is directly placed on the tipping ram, prevents the body from unexpectedly falling down (e.g. when hydraulic hoses break).

The double oscillating frame on which the cylinder is mounted allows to compensate the torsions due to the tipping strains and effectively protects the trailer from distortions.

JOSKIN principle

Branking system

In order to adapt your machine in the best possible way to the braking system of your tractors, it is possible to choose between hydraulic, air or dual (hydraulic/air) braking system. The air braking system is part of the standard equipment on triple-axle models and also allows you to choose a proportional system regulating the braking power in proportion to the load.

Tipping stabilizer

The tipping stabilizer with weight transfer system (or its pre-equipment) is standard mounted on Hydro-Tandem and Hydro-Tridem.

On a Roll-Over bogie, two rams are connected to the chassis. When tipping, the circuit will exert a pressure on the rear axle of the bogie in order to lock it in its position and in this way stabilize the tipping trailer.

Strong and Tight Bodies

Tipping trailers with drop sides are standard manufactured in the same special high tensile steel as the one used to manufacture road transport vehicles. It is the best guarantee of solidity for a relatively low weight. The bottom plate is 4 mm thick. The drop sides have a structure with closed profiled tubes, which allows to increase the resistance to pressure of the walls and give a fluid and modern design to the machine.

In order to ensure a longer life span, the chassis of the JOSKIN tipping trailers with drop sides, except the one of the Trans-EX, are completely hot dip galvanized.

The tipping trailers with drop sides are standard fitted with highly resistant synthetic rubber seals all around the body allowing a perfect tightness of the tipping trailer, even with small grains or products like rapeseed.

Modularity and Simplicity

JOSKIN tipping trailers with drop sides were developed to be as modular as possible. Many volumes and heights are available, which allows to reach higher loading volumes. The side panels can be demounted in order to have a bale trailer.

The handles to open the side panels were designed in such a way that they are easy to use. With their large length and the rubber at their end, they ensure an easy opening/closing.

Tipping Adapted to all Situations

In some difficult to reach places or in order to tip precisely, it can be useful to be able to tip on the sides of the trailer. It is the purpose of the "three-side tipping" option that allows to tip backwards, to the left or to the right. In this case, the tipping ram is fastened to an oscillating frame and the side tipping angle is limited by an end-of-course cable.

Safety and Comfort

JOSKIN dropside tipping trailers are all standard fitted with a rear yoke with complete connections for the lighting, braking system and tipping of a second trailer. The low center of gravity of the tipping trailers ensures a better stability and in this way an improved driving comfort both on the roads and in the fields.

Safe Tipping

The telescopic tipping ram is mounted on a double oscillating frame fitted with greased bearings and integrated in the chassis at a more forward position. This system compensates the torsions due to the tipping strains and effectively protects the ram and body from distortions. The body tipping is also ensured by the two robust hinges including bolted axis with large diameter. The back- and upwards position of the hinges increases the unloading height.

The standard mounted safety valve, which is directly placed on the tipping ram, prevents the body from unexpectedly falling down (e.g. when the hydraulic hoses break).

JOSKIN principle

Tapered, Light and Strong Body

The bodies of the JOSKIN Trans-KTP construction trailers are made fully of high tensile steel of the HARDOX 450 type, which has very interesting tensile properties, as it takes its initial shape back after deformation. Compared to traditional steel, its tensile limit is indeed 4 to 5 times higher.

All bodies, including the doors, are manufactured with 2 steel sheets, without any linking cross-weld. Thanks to this manufacturing process, the empty weight of these tipping trailers is significantly lower and therefore allows transportation of higher payloads, without compromising on sturdiness.

The tapered shape of the body makes sure the contents of the trailer flow out freely. This unmatched property is further reinforced by the successive folds aiming at smoothing off the edges of the body.

Tipping Accessories

For models 9, 11 and 15 T, two hydraulic pumps with a 55 l capacity are available (PR660: 53 l/min at 1,000 rpm and PR980 : 70 l/min at 1,000rpm). They can optionally be fitted with a electric or hydraulic control.

It is also possible to choose a front tipping ram instead of the one under the body on the front part of the chassis for models 22/50 (36 l), 27/55 (49 l) and 27/65 (76 l). This option requires a galvanized headboard in order to protect the ram.

An industrial hydraulic pump (150 l/min) with electric tipping and lowering control (1,000 rpm) can replace the tipping function directly connected to the hydraulic system of the tractor. This pump has a "quick lowering" function and is part of the standard equipment on the 27/65 TRM model.
