Benefits and Features

  • More productive by design. Shears are designed as a system solution to cut more tons per day and make you more money by balancing machine capabilities, shear cylinder size, jaw depth and opening, and leveler arm length.
  • Increase cut efficiency by up to 15 percent and reduce blade wear with the dual offset apex jaw design.
  • Accurately place the jaws in optimum cutting position without moving the machine with the standard 360° rotator on the S3000 Series.
  • Power is consistent through the entire cutting cycle.
  • The shears are optimized for Cat excavators to ensure proper matching, optimal cycle times, and range of motion.
  • Increase cutting efficiency with tapered spacer plates which reduce jamming and drag.
  • The cylinder rod is completely protected inside the frame reducing downtime and the risk of damage and allowing for a slimmer design for better visibility.
  • The jaw relief area allows material to fall away freely without hindering the next cutting cycle.

  • Reduce maintenance costs with the new Bolt-on Piercing Tip. Dowels protect the bolts from stress that leads to loosening and a bushing equalizes force on both halves of the tip to help prevent splitting.
  • Work confidently with demanding hydraulic requirements. Major hydraulic components are built with a 4 to 1 safety factor and can withstand pressure spikes up to 20,000-psi (1378 bar).
  • Increase overall durability with the solid plate construction of the upper jaw.
  • The housing is designed with a 60 percent safety factor in yield strength and high-stress areas are built with extra thick plates.
  • The heel plate is constructed of AR400 high-wear resistant material to provide long life between weld build up and replacement.
  • Endure high forces with confidence with the oversized torque tube.

  • Easily and safely complete maintenance tasks. Shears can be greased at ground level along with the machine stick cylinder pin and boom pin.
  • Reduce downtime with field serviceable swivels. Removing and resealing can be done quickly and easily while the shear is mounted to the machine, without the need to take it to a shop.
  • Service and adjust the pivot group without the need for any special tools. The side play can be easily adjusted by simply tightening the pin.
  • Easily change the tip and flip the blade in thirty minutes with standard tools.
  • Access the cylinder’s hoses and speed valve easily from the side of the shear. This feature eliminates the need for a cover that can fall off and need repaired.
  • You are supported. The Cat Dealer Network is your one point of contact for all your service needs.

  • Connecting your shear to a variety of machines has never been easier. Dual high-pressure ports allow the shear to attach to any compatible machine regardless of the hydraulic layout.
  • Meet your specific needs with straight and rotating configurations and boom and stick mount options.
