Enhanced safety and positive driving performance thanks to hydro-pneumatic suspension chassis

The hydro-pneumatic chassis gives you a wider wheel spacing of 1085 mm for safe driving characteristics in all situations.

An impressive increase in driving comfort has been achieved by fine-tuning the suspension characteristics. Using a different hydraulic accumulator when the loader wagon is empty from the one when the wagon is full noticeably increases driving comfort.

A decisive advantage of this new hydro-pneumatic suspension is the axle guidance provided by the longitudinal linkages. As a result the chassis is extremely stable on slopes and enhances driving safety at high transport speeds.

The large axle compensation of up to 270 mm ensures better climbing ability on inclines, in the clamp and on poor quality roads.

Standard spring version, mechanically lockable
Wide support of the guide springs with anti roll bar effect
Highest level of driving comfort in traffic and off-road
Optimum braking power thanks to equal axle load distribution
Intelligent steered axle driver assist system - axle lock controlled by direction detection and angle sensor are optional
Steered axles and EBS brakes are optional

The entire vehicle is designed in accordance with regulation (EU) 2015/68, so it fully complies with the latest legislation

Hydro-pneumatic tandem chassis

Tandem chassis

Hydro-pneumatic suspension up to a total weight of 24 t. Perfect suspension characteristics in the clamp - smooth running in the field and on the road. The high strength longitudinal linkages apply the braking and steering force.

Steering axle as standard
Hydraulic or electro-hydraulic steered axles are optional
EBS braking system is optional

Hydro-pneumatic tridem chassis

Tridem chassis

With steered axles up to a total weight of 31 t. The tridem chassis distributes heavy loads over a large surface area. The pressure on the ground remains especially low.

Larger axle equalisation ensures a uniform distribution of braking force to all axles. This reduces the pressure on the ground to an average of 0.2 bar.

At the same time the wagon follows precisely in the tractor's tracks on steep ground and in the clamp.

Weighing system for hydro-pneumatic suspension chassis

Weighing system

The optional weighing system on the JUMBO enables dynamic weighing as a rough guide while driving, and outputs exact*) measurements when parked (measurement tolerances in the area of +(-2,5 %).

If the maximum value defined by you is exceeded, a warning is displayed on the control terminal and an acoustic signal is given.

Lifting axle on tridem chassis

The lift axle function enables you to increase the drawbar load at short notice in exceptional situations during operation.

A safety pressure valve automatically lowers the lift axle in the event of an overload to protect the tractor. The system is operated conveniently from the control terminal.

Parabolic leaf spring chassis

JUMBO COMBILINE

The parabolic leaf spring suspension on the JUMBO ensures the best ground tracking and load distribution. When braking, a compensator arm ensures the load is distributed dynamically to all the wheels. Perfect suspension characteristics in the clamp and smooth running in the field and on the road are guaranteed.

22.5" or 26.5" tyres
Large spring spacing at front 1100 mm and rear 856 mm.
Strong longitudinal linkages apply the braking and steering force.
trailed steered axle to protect the sward
Intelligent steered axle driver assist system - axle lock controlled by direction detection and angle sensor are optional
Steered axles and EBS brakes are optional

18 t parabolic leaf spring chassis with 22.5" tyres

With an axle load of 18 t you can drive through difficult terrain with this chassis. This chassis together with 22.5" tyres offers a very low centre of gravity, especially for working on inclines.

18 t parabolic leaf spring chassis with 26.5" tyres

26.5" tyres offer even lower rolling resistance in difficult conditions and in the clamp.

Parabolic leaf spring chassis with anti roll bar

The parabolic leaf spring suspension with anti roll bar is unique in creating safety enhanced, positive driving performance. It has an axle load of 18 t, but is equipped with reinforced parabolic leaf springs (24 t). You also get additional stability from the integrated anti roll bar. This makes it much more suitable for working on inclines.

Electronic controlled steering on tridem chassis

To enhance your safety and driving comfort on the road and in the field, you can equip your JUMBO with additional electronic controlled steering. In contrast to mechanical controlled steering, a safety steering computer controls the steering angle together with a hydraulic unit, the steering cylinders and a turning angle sensor on the steered axle. The axle is controlled as a function of the vehicle geometry, angle of the drawbar and driving speed.

You can choose between several steering programs:

Normal steering
Crab steering
Offset

EBS - electronic braking system with RSP - roll stability program

Increasing transport capacities and high transport speeds require the use of modern braking components to considerably improve safety at the same times as reducing operating costs due to worn brake pads and tyres.

The optional electronic braking system adds another level of safety to braking. It prevents the wheels from locking when braking on smooth road surfaces and stops the wagon from skidding. You can keep the vehicle under control much more easily.

Intelligent trailed axles driver assist system

Intelligent trailed axles

This enables you to lock the axle automatically in all operating conditions even without a driving speed signal from the tractor.

A direction-of-rotation sensor axle detects the direction of rotation and the speed and locks the axle within the defined speed range.

The inclination sensor also locks the axle when the defined inclination is reached. If the defined inclination value is exceeded, you can also have a warning displayed on the control terminal screen.
