2017 SEC 20 tons / Stiff-Arm

Our Concrete Crusher crushes rock and concrete easily. Just pick up a slab from the floor and start pressing. Extra welding on the teeth with a weld hardness of 52-56 HRC ensures strength and with the jaw opening at a wide angle of up to 150 degrees for flexibility. It is simple to install and can be used in railway construction, highway construction, general construction sites, and disaster areas struck by earthquakes or housing collapses. The maximum pressure for the concrete crusher is 31 MPA or 4,496 PSI. Adjusting over this level of pressure is not recommended. Normal pressure is about 20-25 MPA or 2,900 - 3,265 PSI. However it depends on the machine as well. The best way to find out is to start at 15 MPA and increase the pressure until the power needed. Tip: The lifespan of the hydraulic cylinder will be longer with lower pressure.
