Jungheinrich Diesel and LPG forklift trucks with hydrostatic drive provide a high handling efficiency, particularly in shuttle operations (e.g. trailer and loading bay operations). The power of this drive technology is demonstrated to full advantage: dynamic acceleration, rapid direction changes and precise driving characteristics. With 5 drive modes, the performance characteristics can be adapted to the requirements of numerous varied applications.
State-of-the-art engines from the automobile industry facilitate precise operation and optimum productivity combined with low fuel consumption by means of their electronic control systems. All motors are distinguishable by low exhaust emission and comply with at least the current EU regulations. A regulated 3-way catalyser for LPG as well as soot filter systems for Diesel trucks are optionally available.
The workplace is optimally designed with the operator in mind. It provides safety, protects the operator’s health and ensures relaxed and concentrated operation – the best prerequisite for high productivity throughout the shift.

Comfortable and productivity inspiring workplace
Ergonomic operator workplace
Comfortable and with a positive influence towards productivity due to the exemplary ergonomics:
Comfortable and with a positive influence towards productivity due to the exemplary ergonomics:
- Easy and safe access due to a large step easily visible from above.
- Floating Cab: vibration isolation due to damped mounting of the power train and operator workplace module.
- Height and rake adjustable, slim steering column with memory function.
- Maximum freedom of movement during entry and exit: the steering column tilts forward by means of a simple pull on the memory function lever.
- Excellent all-round visibility due to special roof and scuttle design.
- SOLO-PILOT, Comfort Display and operating console are integrated into the right armrest and are thus particularly easy to operate and read. The armrest is both vertically and horizontally adjustable.
- Comfortable working environment in any weather due to comfort cabs in various designs (optional).
Active safety
The new Hydrostatic already offers an extensive safety package as standard:
The new Hydrostatic already offers an extensive safety package as standard:
- Deactivation of hydraulic functions if seat is unoccupied.
- No uncontrolled roll-back on ramps or inclines due to the automatic parking brake, even with the motor switched off.
- Excellent stability due to extremely low inherent centre of gravity and high-mounted steering axle. A range of additional options provide even more safety for the operator, the forklift and the load:
- Access Control: The access control system allows operation of the forklift only if “seat occupied” and “safety belt locked” recognition are activated in a defined sequence.
- Drive Control: Automatic travel speed reduction when cornering (analogue to Jungheinrich Curve Control). Additional travel speed reduction occurs with lift heights in excess of approx. 1500 mm.
- Lift Control (includes “Drive Control”): Automatic mast tilt speed reduction occurs with lift heights in excess of approx. 1500 mm. Tilt angle is displayed via an individual display unit. Sideshift centre position selection via push button.
Handling efficiency and drive characteristics
Key advantages of hydrostatic drive:
Key advantages of hydrostatic drive:
- Electronic control for precise adjustment of drive and hydraulic functions.
- Optimum handling performance particularly in shuttle operation.
- Stepless power transmission and high starting torques.
- 5 electronically selectable drive modes ensure optimum performance parameters for every application.
- Automatic engine speed increase during lifting and lowering.
- Very precise control of travel speed: truck “hangs on the accelerator”.
- Optional double pedal operation.
- Low maintenance costs due to direct drive without wearing parts, such as clutch, differential and gears.
Intelligent electronics
- Splash-proof electronic controllers (IP 64) connected to the CAN-Bus system for drive and hydraulic functions.
- 74 Ah 12 V battery/90 A 3-phase AC generator (140 A optional).
- Electronically controlled motors.
- TFG with maintenance-free electronic ignition system.
- Sensitive adjustment of hydraulic functions via electromagnetic valves.
Tyres
Superelastic tyres as standard; choices of nonmarking SE and pneumatic tyres also available.

Brakes
The hydrostatic drive facilitates completely wearfree braking:
The hydrostatic drive facilitates completely wearfree braking:
- Frequent brake pedal operation is no longer necessary.
- In addition, spring-loaded laminated parking brake in oil bath as a maintenance-free, enclosed system.
- Safety on ramps: The parking brake is activated automatically when the truck stands still or the engine is switched off.
Hydraulics
The high performance filter system ensures clean hydraulic oil and a long service life of all components.
The high performance filter system ensures clean hydraulic oil and a long service life of all components.
- Combined suction and return flow filter system for optimum cold run characteristics.
- Hydraulic tank integrated in chassis.
- Ventilation of hydraulic tank via the filter.
- Pressure relief valves protect against excess pressure and overloading.
Mast
All mast components are designed for optimum visibility, maximum stability and long service life:
All mast components are designed for optimum visibility, maximum stability and long service life:
- Slender mast profiles and lift cylinders positioned at the rear for maximum view.
- End cushioning on mast and tilt cylinders for increased handling safety.
