Caterpillar Work Tools B.V. has announced the introduction of the B-Series versions of its mobile Scrap and Demolition shears. The new S320B, S325B and S340B extend the range of B-series to the previously released S365B and S385B shears.
The 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.
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.
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.
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.
