Swivelling bearing for tree digging machines (digger)

A tree digging machine (tree spade) is a specialized piece of equipment used for transplanting live trees and is widely employed in landscaping, horticulture, and urban greening. It allows for careful extraction of trees with their root systems intact.

The slewing bearing in a tree digging machine is a core structural component that enables the rotation of the working mechanism and provides stability during operation. It connects the base of the machine to the rotating upper structure, allowing precise control of the digging mechanism. The bearing must withstand significant axial and radial loads, as well as overturning moments encountered when handling large trees. Its durability and precision directly affect the machine’s safety and transplanting efficiency.
