Large range breakers

Sandvik Large range breakers

Sandvik large-range hydraulic breakers are based on an innovative operating principle that incorporates hammer stroke length, blow energy and Sandvik idle blow protection, allowing the breaker to be matched to the carrier and application for optimized hydraulic efficiency and safety.

Heavy-duty Sandvik large-range breakers are designed for excavators from 27 to 100 tons. These reliable, low-maintenance hydraulic breakers are easy to fit on the carrier and provide excellent productivity for optimal results and a lower cost per ton of material broken.

Applications

  • Primary breaking
  • Boulder breaking
  • Demolition
  • Trenching
  • Civil engineering
  • Tunneling

Advantages

  • Membrane-type accumulator eliminates recharging
  • Twin-handed to allow optimal mounting on both left- and right-handed carriers
  • Sound-suppressed, super-duty housing for minimal noise and vibrations
  • FBE (Fixed blow energy) for optimum productivity
  • Lifetime warranty
  • Safety valve (Optional) to prevent premature failure
  • Ramlube I & II (Optional) greasing kits for longer component life
  • VIDAT tie rods for better reliability
  • Idle blow protector (Optional) to protect from failures and tie rod stress
  • Soft blow sensor (Optional) to minimize blank firing damage
