MTG will be extending its product range, adding new configurations as well as launching a new hammerless locking system for adapters and shrouds.


1. Tooth
MTG Systems StarMet use the MTG Twist hammerless locking solution.
StarMet offers proven reliability (the system has been used in mining machinery since 2006), with greater ease and speed of use, as well as improved safety when assembling and disassembling teeth.
Specific tooth design with advanced self-sharpening, offering the perfect balance between penetration and resistance to abrasion. New range of stronger teeth with more wear material which guarantee increased bucket productivity with such machinery.

2. Adapter
Electric shovel adapters have been designed with the StarMet tooth-and-adapter fitting system and a conventional two- or three-part lip fastener system. MTG is currently developing a hammerless fastener system for these adapters. It’s not required to convert the lip to install the hammerless locking system in an MTG adapter.

3. Wear caps
The adapter allows the use of wear caps where necessary.
Different wear cap designs are available, depending on the soil abrasion level and type of application.

4-5. Shrouds
The new wing and blade shrouds, in combination with a conventional mechanical fastener system, offer full bucket protection.
The robust design extends the working life of the bucket and its productivity.

6. Hammerless locking system
The rope shovels range uses a hammerles teeth and adapter locking system in the Starmet nose of the adapter.

7. Conventional locking (mechanic)
Conventional locking (mechanic) in 2 parts Whisler* system:
1. Insert in C-Clamp
