Proven platform, purpose-built for demanding applications
Built on the Z G3 platform, this system brings the same proven engineering to 400-tonne hydraulic excavators, delivering strong productivity and reduced downtime while simplifying onsite handling.
Its robust design supports consistent performance in challenging mining environments, helping maintain efficiency throughout the equipment's service life.
Key design features across the Z G3 cast lip tooth system
Next-generation tooth design
The improved tooth design supports consistent penetration, longer wear life and simplified installation.
Key features include:
- Optimised wear material ratio for longer life
- Pre-installed metal retainer for faster installation and reduced inventory requirements
- Self-sharpening design that maintains reliable penetration
- Poka-yoke tooth pin hole that prevents incorrect pin installation
Robust adapter design
The durable adapter design supports strength, stability and service life under high load conditions.
Key features include:
- Large contact surface that preserves structural integrity, improves resistance to frontal loads and extends the service life of the adapter.
- Stronger nose design that reduces operational stress, helping to minimise plastic deformation and prevent premature wear.
Optimised lip and lip shroud design
The advanced lip and lip shroud design protects the structure while improving load distribution across the system.
Key features include:
- Lip shroud lodging design ensures a smooth transition between the adapter nose and the shrouds, reducing stress concentrations and extending the fatigue life of the lip
- Wide contact surface between the shroud and lip minimises wear and extends the overall service life of the lip
- Reverse material flow protection decreases wear and impact on the rear shrouds, extending the service life of the lip shrouds
Optimised lip protection system
The lip protection system is designed to protect critical areas while improving installation efficiency.
Key features include:
- Convenient slip-on wear cap design that fits directly over the adapter without a separate locking system
- Robust protection that extends lip life in abrasive operating conditions
Efficient and safe locking system
The locking system is designed to simplify maintenance and support safer, more efficient component handling.
Key features include:
- Single locking system that simplifies tooth change-outs
- Self-extracting pins that speed up maintenance and reduce downtime
- Hammerless locking system for safer and faster maintenance
- Audible confirmation that the tooth is correctly fitted, eliminating uncertainty during installation
