DESCH azimuth gearboxes in thrusters are three stage planetary gearboxes driven by a hydro- or electro motor. Situated between the gearbox and the motor there is a safety clutch. Used in drive units for floating oil rigs via GPS, the gearboxes rotate the thruster by 360 degrees. The output gear connects with the ring gear, which is connected to the thruster.
