Important information about used Liebherr slewing gearboxes
A slewing gearbox is an important component of a mobile excavator or crawler crane. Would you like to know how a Liebherr slewing gearbox works? And when you should replace the slewing gearbox? We explain it to you in this blog.
The operation of a slewing gearbox
A slewing gearbox ensures that an excavator can rotate around its axis with relatively little force. A slewing gearbox consists of various gears that increase the power of the engine.
The location of the slewing gearbox in the excavator
The slewing gearbox is mounted on the upper carriage of a Liebherr. Through the pinion, which connects to the slewing ring, the slewing gearbox ensures that the upper carriage can rotate around its axis.
Wear
A slewing gearbox always wears out, even with normal use. When the gears are worn, play develops between the gears or on the pinion. Wear is easy to check. If you can move the bearings and gears back and forth by hand, they need to be replaced. Ideally, everything should fit together seamlessly.
Replace your slewing gearbox in time
The older the gears are, the faster they wear down during a sudden movement. To prevent your Liebherr from becoming unusable, it is important to replace the slewing gearbox in time.
Attention! Do not replace only a single part in case of wear.
Our advice is to replace the entire swivel housing in case of wear. If only one part is replaced, it will wear out very quickly. Because the old gears do not have the correct thickness and do not mesh properly, friction occurs. The new gear will wear along with the old parts. As a result, it will ultimately cost you more if you replace only one part, because the part will not last as long.
