Benefits & Features

Essential Tool at Scrap & Demolition Sites
Caterpillar offers a range of six shear models designed for Cat Excavators and wheeled Excavators sized from 307 to 385. The smallest shear — the S305 — can be mounted to Skid Steer Loaders or mini-Excavators. Cat Shears can be boom- or stick-mounted, with our without a quick coupler.

Optimized Stability and Productivity
Cat Shears are designed for Cat machines — taking full advantage of the hydraulic flows and pressures to enhance productivity without compromising safety or causing premature wear of the shear and carrier.

Straight Lower Jaw Design
The unique straight lower jaw design effectively enhances the cutting force by facilitating the spreading out of steel along the length of the jaw, instead of concentrating it in the apex where compressed steel mass can often exceed cutting capacity of the shear.

Cutting Edge Design
The four main, side and front knives, or cutters, are fully reversible with four effective cutting edges. Bushings around the bolts of the two front, side, and tip cutters prevent bolts from loosening. Keeping bolts tight avoids potential bolt breakage, lost or damaged bolts, damage to knives and knife pocket, and alleviates time consuming routine tightening. A piercing tip with excellent wear characteristics such as tensile strength and hardness can be repeatedly hard-faced for long life and effective piercing capability at low operating cost.

360° Rotation
Recognize greater productivity with a rotating shear because of the speed and ease with which shear jaws can be placed into optimum cutting position. All Cat Shears are equipped with a rugged 360° rotation system specifically designed to withstand the forces excavators are capable of applying to the rotator area. An additional advantage of 360° rotation is reduced wear of tracks and undercarriage, and surface material on the job site.Rotation reduces the need to move the excavator and position the shear jaw into the best cutting position.

Easy to Maintain Tight Jaw Tolerance
Cat Shears feature an adjustable hub to help maintain an optimum cutting position between the upper and lower jaw, compensating for knife wear.

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

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

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

Machine Compatibility
Cat Mobile Scrap & Demolition Shears are designed for Excavators sized from 303.5 through 385, wheeled Excavators sized from M315 through M322, and Skid Steer Loaders sized from 236 through 287.
