OUR WORKS

What are the types of hydraulic shearing available? 



a)  Alligator shear 

Alligator shears are powered by a hydraulic cylinder and are mostly used for cutting long metal stock like l-beams, angle iron, pipe or rebar, or to prepare scrap metal for shredding by lopping off anything the shredder will not accept or non-metal fittings.

b)  Metal guillotine 

Guillotines consist of a shear table, work-holding device, a gauging device and upper and lower shears. It can be mechanically, hydraulically, or foot-powered and works by clamping the metal with a ram, then moving a metal blade down across a fixed blade to make a cut.

c)  Bench shear 

A bench mounted shear that offers more mechanical advantage through a compound mechanism, bench shears are ideal for cutting rough shapes from medium-sized pieces of sheet metal.

d)  Power shears 

Ideal for blanking large pieces of sheet metal, power shears are either electrically or pneumatically powered and operated by hand. They are generally used for cutting straight lines or large radius curves.

 e)   Throatless shear 

Perfect for making straight, intricately curved or irregular cuts, the throatless shear differs from the other models on this list because its design allows for the cutting material to be freely moved around.
