As an indispensable mechanical equipment for loading and unloading cargo, marine cranes play an extremely important role in ship installation and operation. Among them, the slewing drive system is an important part to ensure that the crane can operate efficiently and accurately.

The slewing drive system is a key mechanism in marine cranes to ensure that hoisted items can rotate on the horizontal plane. It consists of slewing bearing, drive motor, reducer, brake and electronic control system. LYRA bearings have been improved through technology and merged into a unit assembly, which is rotated by manual, electric or hydraulic motors.

In the marine environment, protective measures and corrosion-resistant design of rotary drives are also critical. The rotary drive uses a fully enclosed structure, with three layers of external electrophoresis, making the surface anti-corrosion grade dadaoC3H standard. The design of the double-skeleton oil seal also makes the protection grade reach the IP65 standard. The unique self-locking performance of the worm gear transmission design ensures the safety of the product. It can prevent goods from falling or equipment damage caused by sudden power outage or other unexpected situations.
