Used Liebherr slewing gearbox

A slewing gearbox allows the upper and lower carriage of a Liebherr machine to move independently. If the slewing gearbox or the associated pinion gear is malfunctioning or defective, your Liebherr machine will no longer be operational. Since most problems are caused by wear, it is important to identify wear in time and replace the faulty component. We sell used Liebherr slewing gearboxes, offering a reliable replacement part at a reasonable price.

What is a slewing gearbox?

A slewing gearbox enables the upper and lower sections of a Liebherr excavator to rotate 360 degrees independently. The pinion gear, located at the bottom of the slewing gearbox, drives the slewing ring. Using various gears, the slewing gearbox and pinion ensure precise control and sufficient torque for rotation. A slewing gearbox consists of the following components:

• Slewing motor
• Slewing reducer
• Slewing bearing
• Slewing brake
• Pinion gear

Maintenance of a slewing gearbox

Maintaining the slewing gearbox is crucial for the performance and longevity of a Liebherr excavator. Maintenance should include checking the hydraulic oil as well as inspecting the gears and bearings for wear and damage.

Due to the heavy loads on the slewing gearbox during operations, the gears and pinion experience wear. This can lead to play between components or even cause gear teeth to break. This results in jerky or uneven movements, or in extreme cases, damage to other parts. Although wear is inevitable, proper maintenance can significantly delay its onset.
