Sandvik BR4099i Side-mounted hydraulic breaker has been designed using a revolutionary operating principle that combines stroke length, blow energy and Sandvik’s idle blow protector, allowing the breaker to be modified to match individual applications and improving hydraulic efficiency and safety.
Features
-
FBE (Fixed Blow Energy)
the built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power, yielding optimum productivity in all applications.
-
High pressure membrane accumulator
eliminates nitrogen leakages, ensuring constant maximum impact power – higher uptime and productivity with lower operation costs. Maintenance is easy and there’s no need for recharging in field
-
Easy IBP (Idle Blow Protection)
adjustment in the field ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures
-
Rotatable and easily field replaceable lower tool bushing
reduces maintenance costs
