  • Lattice Mast
  • Tubular Mast

I. Outriggers

Outriggers are hydraulic or mechanical extensions located near the crane’s base that provide additional stability during crane operations. They are deployed to increase the crane’s footprint and distribute the load over a larger area. Outriggers can be of different types, each with specific names based on their position and design.

  • Front Outriggers
  • Rear Outriggers
  • Side Outriggers

J. Slewing Ring

The slewing ring is a large bearing that allows the crane’s upper structure to rotate smoothly. It is located between the upper and lower structures of the crane, enabling 360-degree movement. The slewing ring consists of several sections, , each with specific names based on their position and function.

  • Inner Race
  • Outer Race
  • Rolling Elements

K. Track Shoes
