Jungheinrich Forklift Trucks

Diesel Counterbalance Truck (6000 - 9000 kg)

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

Diesel Fork Lift Truck with Hydrodynamic Drive
(6000, 7000, 8000, 9000 kg)

Lift (standard mast)
3600 mm
Capacity / load
from 6.00 to 9.00 t

  • Hydrodynamic drive for efficient power transfer with maintenance free laminated brakes
  • Large volume 4 / 6-cylinder industrial motors with high torque at low rpm
  • Especially quiet: Only 73 dB(A) in the cab

The Jungheinrich diesel fork lift trucks with hydrodynamic drive (torque converter) offer high productivity over medium to long distances. 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 operation 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 relating to drive 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.


Ergonomic operator position

Comfortable, performance-oriented ergonomics:

  • Easy entry and exit due to low step position, easily seen from above.
  • Operator position completely sealed from motor, with buffer elements providing noise and vibration damping.
  • Infinitely adjustable and mechanically cushioned comfort seat (air cushioning optional).
  • Height/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).
  • Spacious, comfortable footwell 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 thanks to the well-equipped standard cabs.
  • Excellent all-round visibility due to special roof and panel wall design.
  • (Optional) seat turning 180° left.

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 r.p.m. Maximum Torque: 490 Nm at 1400 r.p.m.
  • DFG S90: 6-cylinder-turbo diesel engine (6.6-l-Perkins) with electronic injection producing 90 kW at 2200 r.p.m. Maximum Torque: 545 Nm at 1400 r.p.m.
  • 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.

Strong hydrodynamic drive

The hydrodynamic drive with electronically controlled 2-speed power shift transmission ensures the cost-effective, transmission of power. Other advantages:

  • Precise and smooth power transmission.
  • Automatic shift and electronically controlled shift lock at travel speeds 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.


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.

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.


Two independent brake systems on the front wheels:

  • Foot brake: Hydraulic servo, maintenance free, encapsulated multi-disc, oil immersed brake with servo assistance.
  • Parking brake: Electro-hydraulic disc brake operated via a button located on the display.

Strong mast

  • Slim mast profiles with lift cylinders hidden behind allow an extra wide window of visibility.
  • Optimised view through the fork carriage.
  • Fork carriage in accordance with FEM/ISO-2328-4A.
