The worm-gear type slewing drive is developed by the slewing bearing. It is composed of housing, a turbine ferrule, a worm gear, a motor and kits. Compared with the conventional slewing bearing, the structure is compacted, safe and modularity. The characteristics of modify the main engine. Nowadays, due to the demand for heavy loading, the duplex worm slew drive device has been developed. It has better product structure compactness and high loading ability and higher output torque.
