Jungheinrich Diesel stackers with hydrodynamic drive (converter drive) and turbo diesel industrial engines provide high throughput efficiency and availability also in 3-shift operation.

The industrial engines, specially designed for application in fork lift trucks, provide maximum reliability and long service life even in the hardest applications. High torque at low rpm is also a contributory factor. It facilitates high efficiency whilst at the same time incorporating low fuel consumption and low noise development.

Another virtue of industrial engines is the low exhaust emission that already conforms to future EU regulations. A number of environment-protecting soot filter systems (optional) are also available that ensure requirement-appropriate adjustment to any application.

The 6 to 9 t stackers are also ready for any application with regard to travel and operating comfort. The ergonomic design of the entire workplace offers both safety and comfort and protects the operator’s health. Thus the high efficiency stackers provide the best conditions for relaxed, concentrated, highly efficient operators.

Operator compartment
Comfort and efficiency-promoted through excellent ergonomics:

Simple and safe mounting and dismounting through low entry height.
Operator workplace module completely sealed off from engine. Damped against sound and vibration through hydraulic buffers.
Steplessly adjustable, mechanically cushioned comfort seat (air cushioning optional).
Steplessly adjustable steering column.
Hydraulic levers fixed to the operator seat that follow every seat adjustment automatically.
Travel direction switch on steering column (fixed on acceleration pedal or to hydraulic lever on control valve is available as an option).
Large, comfortable foot room with pedals arranged as in a motor car.
Excellent visibility through mast due to cylinders arranged behind mast profiles.
Clear instrument panel with analogue display and extensive warning and control lights.
Comfortable working environment in any weather through comfort cabs (optional) in various designs.

Engines
Propulsive power is provided by turbo-diesel industrial engines that were specially designed for fork lift trucks:

DFG 660–670: 4.2 l / 6 cylinder turbo-diesel engine with indirect injection and 82 kW power output at 2450 rpm. Maximum torque (370 Nm) at 1800 rpm.
DFG 680–690 and S80: 4.2 l / 6 cylinder turbo-diesel engine (Detroit Diesel D 706 IE2) with direct injection and 82 kW power output at 2450 rpm. Maximum torque (440 Nm) at 1400 rpm.
Efficient engines with low rpm level and high torque.
Clean exhaust emissions clearly below valid emission limit values according to ISO 8178.
400 operating hours service intervals.
Different types of soot filter systems (optional).
120 l fuel tank integrated in chassis.

Drive
The hydrodynamic drive with automatic 2- speed power shift gear ensures economic, requirement-oriented power transmission. Other advantages:

Sensitive and jerk-free power transmission.
Automatic gear shift and electronically controlled shift lock at a travel speed of more than 4 km/h.
Combined crawl speed/brake pedal for sensitive travelling at full lift performance.

Electrics
12 Volt battery with 135 Ah/115 A alternator.

Steering
Maximum steering comfort and high safety through:

Hydrostatic steering for effortless, precise steering.
Steering axle with integrated steering cylinder.

Brake
Two independent brake systems act upon the front wheels:

Foot brake: servo-hydraulic, maintenancefree laminated brake in oil bath with brake power booster.
Parking brake: electro-hydraulic disc brake activated via manual switch and fitted with operation warning light.

Hydraulics
The high efficiency filter system ensures clean hydraulic oil and contributes towards long service life of all components.

Suction filter and extra fine filter in return pipe.
120 l hydraulic tank integrated in chassis.
Ventilation of hydraulic tank via filter.
Pressure relief valves protect against excess pressure and overloading (load sensing technology).

Mast
All mast components are designed for optimised visibility conditions, maximum stability and long service life.

Slender mast profiles and lift cylinders positioned at the rear for wide visual range window.
Clear view fork carriage for optimised visibility.
Fork carriage according to FEM/ISO-2328- 4A.

Options
Various options and attachments are available for adjustments to different application requirements or customer requests.
