Robust Innovation = Low total cost of ownership.

Meet the most important demands of the clients. The DEMAREC DRS Scrap Shear with its 360° rotation was engineered to deliver a scrap shear with a maximum force, highest speed and optimal weight to performance ratio in daily use in scrap yards and demolition sites. This robust tool can be used for a wide variety of jobs including demolition, scrap processing and tire recycling.
With three different mounting options, the DRS line is available in six different sizes, suitable for excavators from 14t to 100t operating weight.

Demarec DRS

This chart gives an indication of the cutting capacity of the DRS Shears based on the assumption of a working pressure of 350 bar, normal steel profiles with a tensile strength of maximum 370 N/mm², and a good condition of the blades. The DRS Shear cuts bigger size profiles in two times as long the web thicknes does not exceed the maximum thickness of the piercing plate.
