Used Liebherr slewing gearbox
What is a swivel cabinet
A slewing gearbox contains the control system that makes it possible for the upper and lower structure of a Liebherr excavator to rotate 360 degrees independently of each other. The pinion is located at the bottom of the slewing gearbox and sets the slewing ring in motion. Through various gears, the slewing gearbox with the pinion is able to control the excavator very precisely and provide enough power for rotation. A slewing gearbox consists of the following components:
- Slew motor
- Slew reducer
- Slew bearing
- Slew brake
- Pinion
Maintenance of a swivel cabinet
Maintenance of the slewing gearbox is important for the performance and lifespan of a Liebherr excavator. During maintenance, the hydraulic oil should be checked, as well as the condition of the gears and bearings.
Due to the heavy load on a slewing gearbox during operation, the gears of the slewing gearbox and the pinion wear out. This results in play between the components or even broken teeth. As a result, the movements of the machine can become jerky or uneven, or in the worst case, cause damage to other components. Although wear cannot be prevented, it can be postponed for a long time with proper maintenance.
