Concrete Crushers

In combination with the newly developed cylinder and perfectly tailored jaw geometry, the TC concrete crushers produce 25% more force on average than similar crushers. The hydraulic system is completely built into the frame and the cylinders are protected by very robust cylinder guards, so the hydraulics cannot be damaged during the work.
