ZMRB rail-breakers are designed for cutting railway and tramway tracks featuring a mechanical resistance up to 900N/mm2. The machine has a compact design and the cylinder is entirely protected from the structure in Hardox and Weldox. The ZMRB rail-breaker is provided with a 360-degree hydraulic rotation and a valve ensuring greater speed during the opening and closing of the unit. The blades are designed to ensure maximum efficiency during the breakage of the railway track. They are four-time reversible and interchangeable with each other.
