Scrap Shearing Machines

Overview

Reinforced mechanical alligator shear scaled up for medium structural sections while keeping the fast cycle time of a flywheel drive.

The Heavy Duty Mechanical Alligator Scrap Shear Machine pairs a larger flywheel and heavier gear train with a reinforced jaw frame, extending mechanical shearing up into medium structural sections that a light-duty mechanical shear can't take.

It keeps the fast, low-maintenance cycle of a flywheel drive while adding the frame mass needed to absorb heavier impact loads without losing blade alignment.

Frequently asked questions

Answers to what buyers most often ask before ordering this machine.

It uses a larger flywheel, heavier gear train and reinforced jaw frame to cut thicker round bar and light structural sections that the standard mechanical shear can't handle.
