Smart tyre savings for reachstackers

The Liebherr system reduces the machine speed to cool down the tyres before they reach a critical temperature which is crucial for higher efficiency, less downtime and less tyre wear.

“When considering the life cycle costs of a reach stacker, the tyres play a significant role,” said Philipp Helberg, Maritime Cranes, Liebherr.

“It is also known that overheating of the tyre is one of the main reasons for premature tyre wear. Liebherr engineers therefore took up the challenge of developing an innovative countermeasure.

Increased efficiency

Reachstacker tyres tend to get very hot the longer they are used at a stretch.

To prevent overheating, some customers have generally reduced the speed of the reachstacker, which leads to a loss of performance and therefore efficiency.

The newly developed Liebherr Smart Tyre Saving System estimates the temperature increase of the tyre based on the axle load and the speed of the reachstacker and only reduces the speed if it is necessary. This allows the reachstacker to run at full speed until the tyres threaten to become hot.

As soon as the point of increased overheating is reached, the machine is briefly throttled back systemically until the tyres have reached a temperature again that does not cause increased wear. This allows the operator to continue to ride at full speed.
