Bucket protection systems for heavy mining
Bucket protection system for hydraulic excavators over 350 tons, draglines and some electric rope shovel configurations, with buckets fitted with a cast lip.
System characteristics
The new MTG Systems TwinMet system features an innovative tooth-adapter hammerless locking system made up of 3 parts: the tooth, the intermediate adapter and the nose, which can be fused or welded to the lip.

Conical pin makes assembly and disassembly of the parts easy.
Benefits of the system
Strength
The design of the nose offers greater robustness to the system and more resistance in maximum tension areas.
The large stabilization areas improve contact between parts and reduce the stress that can occur between them.
The fitting system allows load stresses and traction to be reduced.
Reliability
Horizontal stabilization in multiple axes leads to increased system reliability.
Optimal adjustment between parts improves reliability and reduces their wear.
Hammerless locking system: Conical pin makes assembly and disassembly of the parts easy.
Optimization
Optimum tooth box design that allows an increased wear material ratio.
Reversible system. Parts can be turned around, if necessary.
Tooth designs specific for hydraulic excavators over 350 t. and draglines that offer a high penetration capacity and self-sharpening.
