DFG 660/670/680/690/S80/S90

Diesel fork lift truck with hydrodynamic drive

Comfortable and safe operator cabin through advanced ergonomics

Hydrodynamic drive for efficient power transfer with maintenance free laminated brakes

Exceptionally quiet: only 73 dB(A) in the cabin

High performance 4 and 6 cylinder industrial engines with high torque at low rpm

The Jungheinrich diesel fork lift trucks with hydrodynamic drive (torque converter) offer high productivity over medium to long distance handling operations. In these situations, the advantage of the power and the drive technology can be clearly seen; smooth, judder-free operation and optimal efficiency at medium to high rpm.

The high performance industrial engines ensure high torque at low rpm, thus increasing fuel efficiency and reducing noise. These robust engines are especially designed for applications in fork lift trucks to ensure high reliability and long life even in demanding applications. Soot / particulate filters are available as an option.

These 6 to 9 tonne trucks are also well suited for all applications in respect to travel and operational comfort. The ergonomic angement of the whole cabin offers safety and comfort, protecting the health of the operator, offering the best in operational comfort whilst maintaining peek operator concentration in a relaxed manner.

Operator cabin

Ergonomic cabin
Comfortable, performance orientated ergonomics.

Easy vehicle entry and exit; low step position, easily viewable from above.
Operator cabin completely sealed from engine and suppressed against noise and vibration.
Smoothly adjustable and mechanically cushioned comfort seat (air cushioning optional).
Height and tilt adjustable steering column.
Hydraulic levers fixed to the operator seat (SOLO-PILOT) automatically follow all seat adjustments.
Travel direction switch on the steering column (optionally available on the accelerator or integrated into the MULTI-PILOT control lever).
Abundant and comfortable leg room with combined brake/inch pedal.
Excellent visibility through the mast due to the location of hydraulic cylinders hidden behind the mast profiles.
Comfortable operation in all weather conditions with the comprehensively equipped standard cabin.
Specially designed roof and cabin walls offering exceptional all-round visibility
180 degrees turning (left) seat (optional).

Powerful engines
The turbo diesel industrial engines are specially designed for the required drive power in fork lift truck applications.

DFG 660–690 and S80: 4-cylinder-turbo diesel engine (4.4-l-Perkins) with electronic injection producing 91 kW at 2200 U/min. Maximum Torque: 490 Nm at 1400 U/min.
DFG S90: 6-cylinder-turbo diesel engine (6.6-l-Perkins) with electronic injection producing 90 kW at 2200 U/min. Maximum Torque: 545 Nm at 1400 U/min.
Exhaust emissions below allowable emission values in accordance with ISO 8178 (fulfils exhaust emission part 3a for diesel engines).
Particle/soot filter (optional).
115 litre fuel tank integrated into chassis.

Resilient hydrodynamic drive
The hydrodynamic drive with electronically controlled 2 speed power shift transmission ensures an economic transmission of power. Other advantages:

Precise and smooth power transmission.
Automatic shift and electronically controlled shift lock at travel peeds of more than 4 km/h.
Inch pedal (combined crawl-speed/brake pedal) for precise travel during full lift capacity.
Travel comfort packet (optional) with automatic increase in rpm during lifting, hydrostatic handling and large multifunction display. Especially suited for reversing and manoeuvring.

Service
Low service costs through good accessibility.

Tiltable cabin – hinged at the rear and hydraulically operated.
Simple access for daily maintenance (oil and water).
Long service intervals of 500 hours.

Intelligent electronics
Splash proof electronic drive and hydraulic controllers (in ccordance with IP 64) connected via CAN-Bus.

12 Volt battery, 135 Ah/115 A alternator.
Precise control of hydraulic functions using electromagnetic valves.

Precise steering
The maximum in steering comfort and highest safety through;

Hydrostatic steering for extremely light and precise steering.
Steering axle with integrated steer cylinder.

Brakes
Two independent brake systems on the front wheels.

Foot brake – hydraulic servo; maintenance free, encapsulated oil laminate brakes with servo assistance.
Parking brake: electro-hydraulic disk brakes operated via a button located on the display.

Reliable hydraulics
Fine filtration in the fluid return circuit. * 180 l hydraulic tank integrated into the chassis.

Filtration of hydraulic tank ventilator.
Pressure release valves protect against over pressurisation and overload.

Strong mast
Slim mast profiles with lift cylinders hidden behind allow an extra wide field of view.

Optimised visibility through the fork carriage.
Fork carriage in accordance with FEM/ISO-2328-4A.

Additional equipment
Many custom build options and various attachments are available in order to adapt the truck to suit customer requests or different applications.
