1. Introduction Metal Shear is a new developed model which used advanced technology on worldwide level. This Metal Alligator Shear is suitable for cold cutting (instead of flame cutting) different type waste metals to short pieces which qualified to the furnace, it could improve the work efficiency as well as save the labor and gas cutting cost. The Scrap Metal Shear is designed with quick unit that can double the shearing speed. Improving 50% eletricity working and saving 50% eletricity. It is original in China. 2. Structure and principle Metal Shear machine applies the hydraulic drive and pre-press unit, it is more safe and reliable. Two operation modes, that is , manual and automatic modes are available. Operating knifes edge length come in two specifications, that is 600 and 700mm. 3. Technical data Model Max. shearing force (KN) Max. press force (KN) Max. knife opening (mm) Knife le…
