Grado Cero Sistemas, SLU, located in Vitoria-Gasteiz, was founded in 1990. We are experts in the manufacture of implements for excavators, with a wide range of buckets, quick couplers and special implements such as the Ripper, Crusher, Screener, top plates, 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 on a plane. Due to the demands of the market, our business led to the repair of excavation machinery, and in 1991 we developed our first quick coupler for excavators.
