SD Series Mobile Slewing Drive

SD planetary rotary drive series is designed to compact design is suitable for mobile, architectural, marine, Material handling, and other demanding applications to ensure adequate performance and stable operation.

This extensive Brevini planetary gear unit is designed for pinion and slewing ring drives.
It has been successfully applied to the steering drive of tower cranes, marine and port cranes, wind turbines, and ship propulsion systems. It can be used in all applications requiring precise positioning. These motion system rotary drives suit the most demanding work in various environments.
The design of the planetary mechanism optimizes the torque performance and radial load capacity to achieve the perfect meshing between the pinion and the ring gear. For precise adjustment, some models have eccentric installation between the gear shaft and the housing shaft. With a wide range of transmission ratios, we can choose the size and type of motor that is most suitable for customer requirements and applications. ever-power is proud of its quality assurance policy, including DNV’s type approval certificate.

Application Area’s

Drive solutions for slewing drives

The rotary drive operates in a very harsh environment, and the space available for installation is often very small. We have specially designed a powerful and compact industrial reducer solution for this situation.
Flexible combination and super long durability: rotary drive industrial reducer
Solution of rotary drive industrial reducer

In many cases, require reducer to provide rotating torque and fix the load. These are mainly related to cranes (tower cranes and slewing cranes), bucket wheel excavators and palletizers. When rotating the bucket wheel arm, the bucket wheel excavator will directly transmit the impact load caused to the reducer.
Our industrial planetary reducer, industrial bevel gear reducer and Bevel Helical gear reducer are very suitable for such applications. They have strong functions and compact shells, and can cope with the harsh operating conditions of swing drive.
Our industrial reducer solutions are durable, powerful and flexible, and meet all your needs in all aspects – power rating and installation. We provide you with all the important components of swing drive at one time:

• Motor and motor bucket
• Equip the brake between the motor and the reducer, with a torque limiter to prevent excessive load
• protection cover
• Main reducer (helical gear or bevel gear helical gear)
• Planetary reducer with gear shaft and output expansion housing
• Output gear
