The demolition shear is an attachment used for demolishing all kinds of reinforced concrete structures. With high-strength steel material and powerful hydraulic pistons, it explodes the beams of the buildings. By cutting the iron and the connection columns inside buildings, the Shear demolishes low-rise or multi-storey buildings silently and safely, and recycles the iron in the rubble through separation. The Demolition Shear is an equipment that allows such works to be done quietly, quickly and safely.
