New Shear S300 B-series scrap shears provide contractors with enhanced processing time and improved durability

Caterpillar Work Tools B.V. introduces the new mobile Scrap and Demolition shears S320B, S325B and S340B series for hydraulic excavators. These shears extend the range of B-series to the previously released S365B and S385B shears.

"The performance and durability improvements will further build on the already excellent reputation of the S300 B shears" said Dave Becktel, Commercial Manager, Caterpillar Work Tools B.V. "With an emphasis on quality, value and safety Caterpillar has improved on our already excellent line of scrap shears".

The robust shear and knife design improves cutting performance and the hardened piercing tip of the upper jaw maximizes productivity when piercing is required. All S300 shear models are equipped with field proven 360° rotators ensuring a quick and precise placement of the jaws in an optimum cutting position without moving the excavator. The high force-to-weight ratio enhances faster cycle times, resulting in more cuts per hour. "

Enhanced performance

Cat shears are designed to cut and reduce the size of metal items commonly found in scrap yards and demolition sites. The straight lower jaw works with the apex of the upper jaw, compressing and flattening the steel before the cut. The straight lower jaw maximizes shear force and creates a more efficient cut.

Improved Durability

The new shape of the housing provides improved protection for shear components and better positions the jaw relative to the stick. The cutting edge design greatly improves the protection of the cylinder that eliminates the use of a cylinder guard by extending the housing to cover the cylinder rod. A newly designed hub is better protected against damage.

Optimized Serviceability

Large access panels on the top, bottom and sides of the shear housing make it easier to service inside components. The unique hub adjustment quickly compensates knife wear. The threaded pivot-pin holds the jaw in positive alignment without the need for external retention. The gap between upper and lower jaw can be easily adjusted, keeping cutting capability high - even as blades wear. The piercing tip in the upper jaw is made of hardened steel and can be repeatedly hard faced - helping increase the intervals between tip replacements.

Enhanced Safety

Safety during maintenance work is enhanced with an improved jaw and rotation service locks. A standard flagged pin is used to secure the cylinder rod to the moving jaw. This pin design is very similar to those used elsewhere on a caterpillar excavator and makes maintenance more intuitive and lets techs use standard tooling.

The S320B, S325B and S340B series fit CAT excavators from 10-ton to those in excess of 60-ton operating weight. The shears can be mounted on either the boom or stick, and caters to all needs for scrap-processing- and demolition applications.

Caterpillar supports its work tools with a comprehensive range of pre- and after-sales services that cover everything from advice on work tool selection to operator training, equipment management, and a range of financial and insurance products.
