J static shear consists of a “one piece” structure. In the rear part of the structure, on the opposite side of the shear frame, a platform develops integral with the squeeze-box. Under the platform is placed the main compression cylinder, the diesel tank, the electric and hydraulic components, sideways the platform is placed the electric motor or diesel engine necessary for the independent running of the machine. The pre-compression-box (patented) permit to easily reduce the volume of bulky scrap. J shear is medium size machine, fast, robust and safe. The surfaces of the shear & baler in contact with scrap are with “integrated” highly wear- resistant steel. The machine works directly on the ground, does not need foundations and permissions. Shear of this group, besides shearing the scrap, can produce bales, that are automatically ejected.
