Dual-worm slewing drive is usually installed horizontally and is mainly used in engineering machinery. As 2 worms drive the worm gear, it can output more significant driving moments, more reliable self-locking performance, and better safety performance in restricted space. And it is usually applied on occasions of low speed but at a more significant moment, such as flat-form tire trolleys and overhead traveling cranes.


1. For situations where high torque is required, we introduce and recommend dual worm slewing drives which equip with a worm wheel and have high scuffing resistance.

2. Driven by 2 worms, its output torque and performance are higher than that of a single worm slew drive

3. Through excellent heat treatment, hardness of its is high

4. In the typical case, our worm reducer is connected to a hydraulic motor by a universal input hole.
