Tooth-adapter fitting system increasing the productivity of excavators from 10 to 400 tonnes and loaders from 9 to 350 tonnes.

Note Following the launch of the new Promet II references, we have implemented dimensional changes to the StarMet adapters (mining sizes) in order to improve compatibility between the two ranges (Promet II and mining Starmet Adapters).
NEW MTG Systems StarMet: discover the new Starmet sizes 15, 20, 30 and 40. A new range of hammerless products, ideal for construction.

Greater security

MTG Systems StarMet built-in innovative locking solution MTGtwist.
This innovative solution offers:

When changing the teeth:
• Safety: No possibility of impact accidents due to flying metal particles.
• Ease: Tooth changing effort lower than using a hammer.
• Easier to use: One person can change the tooth

When working:
• Safer retention: Tried and tested system offering excellent retention, preventing tooth loss.
• Re-usable pin: The pin is rugged and does not suffer during assembly and disassembly. It can be re-used in most cases.
