What is the crane slew center?

In the field of construction machinery, the crane is an indispensable piece of equipment, and the crane's slew center is one of its core functions. This article will introduce in detail the definition, function, structure and related technical parameters of the crane slewing center, and provide you with a comprehensive analysis based on the hot topics and hot content on the entire network in the past 10 days.

1. Definition of crane rotation center

What is the crane slew center?

The crane slew center refers to the center point where the upper structure (including cab, boom, etc.) of the crane rotates around the lower structure (such as chassis) when the crane is working. This design enables the crane to operate at a fixed position 360 degrees without blind spots, greatly improving work efficiency and flexibility.

2. The role of the crane rotation center

1.Improve scope of work:Through the design of the slewing center, the crane can cover a larger working area without moving the chassis.
2.Enhance stability:The design of the rotary center helps disperse the load during hoisting and improves the overall stability of the equipment.
3.Reduce wear and tear:Reasonable rotary center design can reduce the wear of mechanical components and extend the service life of the equipment.

3. Structure of crane slewing center

The crane slew center usually consists of the following key components:

Part nameFunction description
Slewing bearingConnect the upper structure and lower structure to achieve 360-degree rotation
Drive unitProvide power to drive the upper structure to rotate
control systemControl slew speed, direction and stop

4. Hot topics and content on the entire network in the past 10 days
