ACCESSORY DRIVE GEARBOXES

Kawak designs and manufactures specialized accessory drive gearboxes for our FAA approved products as well as for custom applications covering a wide range of aircraft and industries. These gearboxes are used to transmit power from turbine engines, helicopter transmission accessory drive pads, and other various outputs into auxiliary devices such as hydraulic pumps, generators and hoist systems.

When coupled with one of Kawak’s hydraulic systems, Kawak gearboxes provide power for attached or suspended implements used in many aviation industry applications. The following are some examples of the aircraft applications currently using Kawak gearboxes and FAA approved hydraulic systems.

  • Geophysical survey receiver array hoists
  • Airplane and helicopter spray systems
  • Helicopter forestry equipment
  • Helicopter hover refill pump systems
  • Helicopter fire tank control systems
  • Aircraft air conditioner systems
