SE9 Inch Slewing Bearing Drive With Servo Motors For Cranes And Liftings
Slewing Bearing Drive Description
Cranes are equipment that lifts or moves heavy objects horizontally, and are widely used in various fields such as manufacturing, engineering, and transportation. Therefore, the types of cranes are also diversified due to the application in different industries, for example, there are single and double girder overhead cranes, suspended overhead cranes, gantry cranes, portal cranes, stationary cranes, tower cranes , jib crane, etc. Additionally, lifting weights range from 1.25kg to 1,000t. However, no matter what kind of crane it is, there is always the fact that where there is rotation, there are slewing bearings.

About Us
Changzhou hangtuo uses a double-envelope technology to produce a slewing drive with ring-wound worm technology as the most important means to maximize load and improve transmission efficiency and accuracy. When the worm is engaged with the slewing bearing, multi-tooth engagement can be achieved, and when the worm is engaged, only one-tooth engagement can be achieved. The increased tooth surface engagement of the 5 to 11 teeth thus greatly enhances the strength and power of the transmission. Our range of slew drive is available in several series and covers a wide range of models. The performance range and installation dimensions can meet the needs of different applications. At present, our products can be divided into 9 basic models, the diameter of the raceway ranges from 75mm to 800mm. The load range is from 6kNm to 220kNm, the torque output is from 200Nm to 63kNm, the turning torque is from 500Nm to 271kNm, and the transmission reduction ratio is from 30:1 to 156600:1. The installation method can be horizontal, vertical or multi-axis.
We produce many different types of slew drives and offer many types of slew drives and drive components. Our slew drives can be self-locking or back-drive. The self-locking slew drive does not reverse when the reverse force is transmitted from the slewing ring to the worm, and there is no need to install a separate brake. Instead of self-locking, it can be driven in reverse. For hydraulic applications, we supply hydraulic motors to our customers. For electric equipment, we can supply gearboxes and various motors for our customers.
