The right tooth for any deployment

Tooth shapes that are adapted to the respective type of ground contribute towards the efficiency of your machine

Tooth shapes that are adapted to the respective type of ground contribute towards the efficiency of your machine

To optimize the cost-effectiveness of Liebherr machines, the shape of the tooth must be adapted to the respective use. Liebherr offers you comprehensive tooth programs with tooth shapes for any task.

Tooth systems from Liebherr

The Liebherr Z tooth system

The optimized tooth design leads to in an increase in efficiency on the construction site with the Liebherr Z system. The low digging resistance, the self-sharpening tooth shape as well as easy tooth replacement without hammering are positive points for the Liebherr Z system. The teeth are made from high tensile steel, which is distinguished by the highest level of resistance and long service life.

Tooth shape Features Areas of application
C-tooth The conical shape helps to achieve very good penetration in compact ground Easily dug ground and weakly compacted ground (e.g. loose, loamy sand, fine to medium gravel, moist or soft clay)
CL-tooth Long, drawn-out point with sharp cutting for very good penetration properties Medium and compact ground types to ground with average plasticity (e.g. hard, loamy sand,
medium clay, fine to medium clay)
CR-tooth The long, drawn-out point enables very good penetration in aggregate material. The broad and thick base of the tooth facilitates a long service life under wear-intensive conditions Abrasive ground, rock (e.g. granite, basalt, sandstone mainly in connection with backhoe bucket deployment)
R-tooth Low cutting width and large wear volume result in high specific penetration force and service life Difficult to dig ground, particularly abrasive ground, rock (e.g. limestone, slate, very hard clay, brown coal)
P-tooth Pointed tooth with good penetration capability even in hard stone Very hard, frozen ground, rock that is very difficult to break (e.g. well set, unweathered shale)
PF-tooth Fork tip with outstanding penetration in extremely compact ground. Can be fitted to corners of bucket as a supplement to the P-points in order to maintain tilt angle Very hard and frozen ground, rock that is difficult to break (e.g. well set, unweathered shale, heavy ore with medium and weak cracks, slag heaps from steelworks)
L-tooth Very good penetration in compact ground. Ideal for precise leveling together with single arm tooth adapter Light to medium ground hardness (e.g. loamy sand, clay, fine to medium gravel)
H-tooth Good penetration in aggregate material. The broad and thick base of the tooth facilitates a long service life under wear-intensive conditions Abrasive ground, rock (e.g. granite, basalt, sandstone; mainly in connection with two arm tooth adapter and intermediate tooth segments)

The Liebherr Uni system

The low construction height and the narrow, self-sharpening tooth shape makes the Liebherr Uni system ideal for best digging with low penetration resistance.

Highly wear-resistant steel assures even under tough conditions the familiar reliability that has already proven its worth among wheel loaders. The side clamping sleeve locking mechanism enables simple and efficient tooth replacement.

Tooth shape Features Areas of application
Standard tooth Symmetrical cap with front cut-away section, self-sharpening, reversible For types of ground that are easy to medium to dig (loamy sand, gravel, soft brown coal, soft / medium clay etc.).
HD tooth Cap with large material volume for long service life when deployed during wear-intensive operations For particularly abrasive ground (granite, basalt, sandstone, stone containing quartz etc.)
Pointed tooth Pointed tooth for good penetration,reversible For very hard and frozen ground, rock that is difficult to break (limestone, slate, brown coal, mining of wall gravel etc.)
