We are experts in the manufacture of excavator attachments, with a wide range of buckets, quick couplers and special attachments such as rippers, crushers, screeners, top brackets., etc. Leaders in the national market for many years, we offer solutions for machines from 1 to 150 tons.

Initially, the company focused on precision machining work based on drawings. Due to market demands, our business shifted towards the repair of excavation machinery, and in 1991 we developed our first quick coupler for excavators.
