We present our new range of ProMet II bucket shrouds for excavators and mining loaders. A series of new products with an improved and optimized design that provides greater bucket protection and ensures better performance with large machines. The new ProMet II range uses the MTGtwist hammerless locking system that allows for perfect locking for the most aggressive applications with the utmost safety.


Maximization of the amount of wear material
The new design has been specifically optimized in line with its use with loaders and excavators, resulting in an increase in the ratio of wear material in our pieces by over 40%. This means that the new Promet II range provides 30% more wear material compared to the equivalent* model of our competitors.

*pieces of equal weight

New locking system for easier and faster assembly.
The locking system of the Promet II range only requires one weldable base to be installed for each blade shroud.
Furthermore, and to make installation of the base even easier, the new references come with positioning guides that enable precise and quick assembly, reducing the machine's downtime

Easy change-over

Only one weldable
base required


Longer Wear Life
The side protectors are reversible, meaning that their position can be interchanged when required, thus extending the life of the protector.

It protects the bucket, increasing its wear life
Reduces exposure of the bucket to impacts and abrasion, extending its wear life.

Improved safety and reduced machine downtime MTG Systems ProMet incorporates the MTGtwist locking solution. This solution offers:
MTG Systems ProMet incorpora la solución de fijación MTGtwist.
Esta solución ofrece:

Safety: No possibility of impact accidents due to flying metal particles.

Comfort: Protector changing effort lower than using a hammer.

Easier to use.
Increased bucket capacity and penetration
Allows you to carry more material and to increase penetration, thereby improving productivity of the machine.


Compatibility with StarMet tooth adapters
The new generation of ProMet II can only be installed with the new generation of StarMet tooth adapters, thus avoiding any possible interferences between the systems:

ProMet vs StarMet compatibility table:

StarMet Adapter reference Date of order PROMET II PROMET
1MA-size-WC < 2012 NO YES
1MA-size-WC + one digit
1MA-size-WC + blade thickness in mm > 2013 YES YES

Interferences while
assembling are avoided

Compatibility with ProMet
For design reasons, most references are not compatible between the two designs.
