Drive gearboxes

ZOLLERN drive gearboxes are available as compact gearboxes and shaft-mounted gearboxes. They stand out for high performance under difficult and unfavourable conditions.

ZOLLERN compact gearbox range
11 model sizes with maximum output torques of 30 to 2,300 kNm

ZOLLERN shaft-mounted gearbox range
6 model sizes with maximum output torques of 165 to 1,800 kNm

Their most remarkable features and special characteristics are

  • compact construction
  • high efficiency
  • long operation life
  • ease of maintenance

With these characteristics the machine designer will get a ready to install unit and will achieve economic solutions even in confined space conditions.


  • Wheel drives for rubber-tyred vehicles
  • Sprocket drives for diggers, cranes and chain-driven special equipment
  • Drive trains for railway vehicles
  • Cutting wheel and rolling mill drives

Drive options
Hydraulic motors, either fixed or adjustable, are the most usual option and are flange mounted. Electric motor drive solutions are also available on request.

Multi-disc brakes
A spring-actuated multi-disc type brake is installed as standard with the hydraulic motor drive. The braking torque is adjusted to correspond to the motor torque.

Sealing (compact gearbox)
Sliding-face seals are used between the fixed and rotating parts of the compact gearboxes. They reliably protect the gearboxes from any ingress of moisture or dirt.

Sealing (shaft-mounted gearbox)
The seal here is a radial shaft seal with protective labyrinth seal. Here again, the gearbox is reliably protected from external contamination.
