Tower crane slewing bearing

The tower crane slewing bearing is a key component of the tower crane, enabling horizontal rotation of the overall structure and providing 360-degree flexibility for the construction site. It supports lifting and hoisting operations, allowing the tower crane to be positioned accurately and adapt to complex construction site conditions.

Strong load-bearing capacity

Crane slewing bearing are usually designed to withstand large vertical and horizontal loads.

Flexible rotation

The slewing bearing allows the crane to rotate flexibly in the horizontal direction to meet various work requirements.

Wear-resistant and corrosion-resistant

Slewing bearing are usually made of wear-resistant and corrosion-resistant materials to ensure their long-term stable operation and reduce maintenance costs.

High reliability

As a key component of the crane, the slewing bearing is usually precision designed and manufactured to ensure its high reliability.

  Application examples

The superior performance and stability of the tower crane's slewing bearing are crucial to the smooth progress of high-rise buildings and large-scale projects, providing strong lifting and handling capabilities for construction sites.

  • Building lifting: The slewing bearing enables the tower crane to accurately position the hook to different areas of the building to facilitate the lifting of various building materials.
  • Concrete pouring: In the construction of high-rise buildings and structures, tower cranes can accurately transport concrete to the required location through slewing bearing to achieve overall construction efficiency.
  • Lifting and handling: Slewing bearing support tower cranes in lifting and handling operations on construction sites, including handling construction materials, equipment, and other heavy components.
  • High-altitude operations: Tower cranes can perform high-altitude operations through slewing bearing, including decoration, cleaning and maintenance of building exterior walls.
  • Bridge construction: In bridge construction, tower cranes use slewing bearing to flexibly control the hooks for hoisting and installing bridge components.
  • Wind farm construction: The application of slewing bearing in wind farms enables tower cranes to install and maintain wind turbines and their related equipment.
  • Equipment maintenance: The slewing bearing supports the tower crane to maintain and repair construction equipment and mechanical components to ensure their normal operation.
