At present, the main products circulating in the market are: box shears and mobile box shears. The box shear is an efficient scrap steel and scrap metal processing equipment. The original designer of the box shear comes from Europe. It has a compact structure and a one-piece design for easy movement. It can be controlled by a hybrid of an engine and an electric motor, or it can be controlled separately by an engine or an electric motor. The mobile box shear is a mobile equipment developed and innovated on the basis of the box shear. The support of the foot cylinder makes it fixed on the loading vehicle to realize the vehicle movement, and the engine is controlled to facilitate site replacement.
