Mobile Planetary Drives


Track Drives


Brevini planetary track drives are designed for tracked vehicles and earth-moving machines. They have a heavy-duty casing, a short overall length, and great radial and axial load capacity.

Our gearboxes are provided with integral multidisc parking brake and have been designed for direct mounting of hydraulic plug-in motors. The careful choice of the materials and design allows our track drives, CTD and CTU, to be used in the most severe environmental working conditions. Brevini planetary track drive units are the perfect solution for crawled undercarriages, drilling, crushing, screening and piling machines.


  • High torque and load capacities, to carry equipment over the roughest and steepest terrain.
  • Designed to allow mounting of plug-in motors.
  • Integral multi-disc parking brakes, while still keeping the drive compact.
  • Steel or high-impact spheroidal cast iron structure.
  • Main bearings provided for high radial and axial load capacities.
  • Easy maintenance: filling and draining ports locations easy to reach.
  • Front mechanical seal designed specifically for the earth-moving machines.

Wheel Drives


Brevini planetary wheel drives are designed for self-propelled vehicles with hydraulic or electric motor. They are available in a wide range of ratios, allowing the power system to operate at optimum efficiency. Whatever the type of machine is, up to 2.5 m of tire diameter and 50 tons each wheel, Brevini has a suitable solution to drive it. The versatility of this range of planetary wheel drives is assured by a wide choice of braking systems (drum brakes, disc brakes, negative acting multiple discs parking brake). Thanks to the wide ratio range, there is a solution for any type of transmission and application. The manual declutch system can disengage the gear unit from the motor for emergency towing.


  • Big radial and axial load capacity due to the use of strong tapered roller bearings.
  • High torque capacity
  • Reliable oil seal protection, designed according to our field experience.
  • Universal and SAE input direct mounting flanges
  • The units are designed for their direct mounting into the wheel rims.
