Slewing gearboxes
ZOLLERN slewing gearboxes are primarily used for turning gear rings and large-diameter anti-friction slewing rings, for example in cranes. They have been proven under the harshest of application conditions.
The slewing gearboxes are based on a modular design and are also available with an enhanced scope of delivery (motor, coupling, brake).
The pinion-slewing ring tooth pairing is checked for every application case and the tooth form of the pinion is optimised to ensure a long service life.
