What is a slewing drive?

The slewing drive adopts the structure of slewing bearing and annular worm, which can achieve multi-tooth contact, has the characteristics of large transmission torque and stable operation; can withstand large radial and axial loads and strong overturning moment.

Three advantages

  • Modular
    Due to the high integration of the slewing drive, the user does not have to purchase and process each component of the rotating device one by one, which also reduces the preparation process at the beginning of product production to a certain extent, thereby greatly improving labor productivity.
  • Safety
    The worm gear drive has the characteristics of reverse self-locking, which can realize reverse self-locking. This feature makes the slewing drive widely used in lifting, aerial work and other equipment. While improving the technological content of the main engine, it also greatly improves the operation stability of the main engine and the safety factor of the operation.
  • Simplified mainframe design
    Compared with traditional slewing products, the slewing drive is easy to install, easy to maintain, and saves installation space to a greater extent.
