Large range breakers
Sandvik Large range breakers are based on an innovative operating principle that incorporated breaker stroke length, blow energy and idle blow protection, allowing the breaker to be matched to the carrier and application for optimized hydraulic efficiency and safety. The Large range breakers come with a factory-installed RD3 remote monitoring system for your efficient operations.
Sandvik’s Large range breakers are reliable, low-maintenance and easy to fit on the carrier. They provide excellent productivity for optimal results and a lower cost per ton of material broken. The Large range breakers are compatible with carriers from 26 to 120 tons.
Applications
- Boom mounted applications
- Primary breaking
- Boulder breaking
- Demolition
- Trenching
- Civil engineering
- Tunneling
Advantages
- Superior fleet management with the RD3 remote monitoring system
- Membrane-type accumulator eliminates recharging
- Twin-handed to allow optimal mounting on both left- and right-handed carriers
- Sound-suppressed, heavy-duty housing for minimal noise and vibrations
- FBE (Fixed Blow Energy) for optimum productivity
- Sandvik’s patented Ramvalve to protect against premature failure
- Ramlube I & II greasing kits for longer component life (Optional)
- VIDAT (Vibration Dampened) Tie rods for better reliability and longer working life
- Field adjustable Idle blow protector (IBP) to protect from failures and tie rod stress
- Stroke selector allows the operator to match breaker to material and application for optimized breaker operating
