The right tooth
for every appl ication
The economic use of a hydraulic excavator is only possible if the tooth shape
matches the relating application. Liebherr offers a broad tooth program with tooth
shapes for every task.
Due to its low overall heigth and the slim, self-sharpening tooth shape the
Liebherr U-system stands for best diggning behavior at lowest penetration
resistance. Highly wear-resistant steel provides familiar reliability under hard
conditions, which has already stood the test on wheel loaders. The lateral rolled pin
fastening allows a simple and safe change of teeth.
