7 Ground Engaging Tools
Innovative Design
With its unique design philosophy and innovative approach, the Liebherr Mining
Ground Engaging Tools solution is able to exceed the most stringent customer
expectations. The Liebherr solution reduces owning & operating cost by extending
the equipment life.
Bucket Side Wall Protection
The rounded area of both wing shroud and corner wear cap is fully adaptable
to each bucket side plate shape. To reduce downtime, the corner wear cap is
mechanically attached to the corner adapter and can be removed independently
from the lower wing shroud.
Thanks to the wing shroud “peanut” concept, the material is distributed on both
ends to maximize penetration over the lifetime of the part.
Self-Sharpening Design
Machine operators will experience an optimal combination of bucket penetration
and high fill factor over the teeth lifetime, thanks to the self-sharpening tooth design.
One Single Locking System
To increase machine uptime and reduce tooling to one unique extraction tool, the
teeth, shrouds and wing shrouds are equipped with one single locking system. In
addition the wear cap does not require any locking system as it is slipped on the
adaptor and locked by the tooth.
Truly Hammerless System
A single and easy-to-carry double side extraction tool designed by Liebherr to
match the complete range of tooth sizes.
