When it comes to recycling and processing scrap metal, efficiency and precision are critical. One of the most widely used machines in this industry is the alligator shear. Known for its powerful cutting force and versatile design, the alligator shear is the ideal solution for processing a wide range of scrap metals, from steel bars to copper and aluminum profiles. Its name comes from its hinged jaw-like blades, which resemble an alligator’s mouth, delivering strong cutting performance with each stroke.
What is an Alligator Shear?
An alligator shear is a hydraulic cutting machine designed to cut scrap metals into smaller, more manageable pieces. It uses a hinged jaw mechanism powered by hydraulics to provide high shearing force, making it suitable for ferrous and non-ferrous metals. Its compact size, ease of operation, and strong performance make it popular in recycling yards, metal processing plants, and foundries.
