Jaw Design

Unique straight lower jaw design effectively enhances the cutting force by facilitating the spreading out of steel along the length of the jaw, maximizing the shear cutting force.

360-degree Rotation

Operator can spin the jaws 360 degrees in either direction to quickly position the jaws for a cut.

Reversible Knives

The four main, side and front knives are fully reversible with four effective cutting edges.

Easy Maintenance

Large access panels on the top, bottom, and sides of the shear housing make it easier to service inside components.

Protected Cylinder

Design of the shear housing provides full protection of the cylinder throughout the complete cutting cycle.

Completely Cat

Only Caterpillar offers an integrated machine-hydraulics-shear system supported by Caterpillar from front to end, throughout the life of the system.
