Every application is unique and has different requirements. Our gearboxes are designed to accommodate a variety of accessories to ensure maximum efficiency and productivity.

Negative Static Multi Disc Brakes
Dinamic Oil designs and produces all of our own wet negative static multi-disc brakes in house. The brakes are optional accessories for our planetary gearboxes and winch drives and offer a wide range of torque ratings. Brakes can also be configured as “dry” brakes, that allows them to function at increased input speeds without overheating, others can accommodate sprag clutches. Each brake is 100% tested to ensure the rated braking torque is verified.

Other accessories include:

  • Torque arms
  • Shrink discs
  • Two-speed inputs and disconnects
  • Water cooling jackets
