Side Type Rock Breaker Features
FAQ:
Question: What is a Hydraulic Breaker Accumulator?
Answer: The function of the accumulator: the inside of the accumulator is filled with nitrogen gas, is to use the hydraulic breaker to store the remaining energy and the energy of the piston recoil during the previous blow and release the energy at the same time during the second blow to increase the blow impact
Question: Do all Hydraulic Breakers Need an Accumulator?
Answer: The accumulator is installed when the breaker itself cannot reach the impact power to increase the impact force of the breaker. All general small ones do not have accumulators, and medium and large ones are equipped with accumulators.
