More characteristics
Our robust trucks with torque converter and hydrodynamic drive give you high productivity coupled with high reliability for all transport tasks. The strengths of the hydrodynamic stacker can be clearly seen especially over medium and long-distance routes; smooth, judder-free operation and optimum efficiency at medium and high speeds.
Tried and tested worldwide, the Kubota industrial motors already ensure high torque at low rpm. The benefit: A reduction in fuel consumption and minimised noise. These robust and particularly reliable motors have been specially designed for use in fork lift trucks and have a long service life.
The optimised efficiency of the Jungheinrich drive axle with integrated, wear-free wet-disc brakes represents outstanding reliability and low service costs. The enclosed design of the braking system helps protect it by eliminating ingress of water or dust, which is typical in harsh conditions.
The operator’s cab is functionally designed with the operator in mind. Visibility in all directions is outstanding. Also contributing to this is the compact mast with its view-optimised chain and hose guide, compact profile nesting as well as two viewing windows in the lift cylinder cross-member. This guarantees focused work and the best requirements for high productivity throughout the shift.
Thanks to the special Jungheinrich counterweight design, the trucks centre of gravity is low and in an ideal physical location between the axles. This results in above-average stability and driving safety.

- Sturdy hydraulic levers positioned for easy use even when wearing gloves.
- Comfortable operator seat with excellent suspension and numerous adjustment options.
- Low vibrations experienced by the operator as overhead guard isolated against vibrations.
- Optimal configuration of display and switches for additional equipment (e.g. lighting and wipers) within the operator’s reach and field of vision.
- Numerous storage options, such as drink holder, documents clip and a compartment for small parts.
- Electric parking brake operated at the push of a button without awkward hand lever in knee and entry area.
- Automotive pedal configuration with non-slip surface.
- Smooth transitions provided by the mast cushioning system.
- High residual capacity at high lift heights.
- Optimum view of the load thanks to lift mast design giving ideal visibility.
- Compact section nesting.
- Hydraulic hoses routed for optimum visibility.
- Viewing window in the free lift cylinder cross-member for safe work at higher racking levels.
Hydraulic control valve in load sensing technology: Due to the lower pressure level, the load sensing system reduces energy consumption while simultaneously slowing the deterioration of the oil.
- Axle concept with optimised efficiency for low fuel consumption.
- Largely maintenance-free multi-disc brakes immersed in an oil bath. Practically no service costs (in comparison with conventional drum braking systems).
- No negative effect on braking due to environmental influences or service related downtime due to the enclosed design.
Improved operator comfort and reduction of human vibrations to a minimum through:
- Floating drive unit.
- Drive shaft combination with universal joints.
- Heavy-duty combi cooler in full aluminium design for motor coolant, converter and transmission oil – without the common plastic manifolds which are susceptible to faults.
- Easy to clean radiator and oil cooler cores.
- Prevention of coolant evaporation due to completely closed pressurised system.
- Reliable operation without a reduction in performance even at extreme ambient temperatures.
- Optimum access to engine compartment due to 90° opening and L-shaped cover.
- Side sections and floor plate easily detachable without the need for tools.
- Minimal truck downtime thanks to simple, rapid and cost-effective maintenance – expert knowledge not required.
- Use of sturdy, high-quality components.
- No truck-specific diagnostic tools or special software required.
- Oil change interval of 500 operating hours.
- Splash-proof electrics, plug and connections.
- Easily accessible, compact fuse box on the panel wall in the operator compartment.
- High driving stability even during dynamic travel thanks to reduced pendulum motion due to high pivot point of the steering axle.
- Minimised tipover risk also without the additional use of electronic assistance systems.
- Displacement of the centre of gravity downwards and forwards due to counterweight design.
- Low centre of gravity, optimised position between the axles.
