Xcentric Ripper

Xcentric Ripper

A full range for hydraulic excavators from 8 tons up to 150 tons 

Made completely of wear-resistant steel, this attachment device is almost maintenance free, less noisy than any other excavation tool, can be used under water without any damage risk and be adapted to countless work sites. Thanks to it’s uncomplicated mechanical design, which has no pricey components, the maintenance cost are very low and down times are ignorable. 

A revolution in rock excavation

The Xcentric Ripper is an excavator attachment developed with the latest advances in excavation and demolition systems in mind.
It meets the highest standards. It was patented by Grado Cero Sistemas, a trailblazer in the industry. Trough it’s design, an outstanding performance can be achieved, allowing more ef cient work.
