The right hydraulic breaker should be selected according to excavator operating weight, oil flow, operating pressure, chisel diameter and working condition. Do not choose only by breaker weight.
Fatores principais de seleção
Match the breaker series with the excavator operating weight range.
Check that the excavator auxiliary circuit can supply the required flow.
Pressure must stay inside the breaker working range for stable impact.
Larger rods suit heavier carriers and harder rock or concrete.
Side, box and top type housings fit different visibility and noise needs.
Rock breaking, trenching and demolition can require different impact classes.
How Peso da máquina Affects Breaker Choice
A breaker that is too heavy can overload the excavator front structure, while a breaker that is too small may not deliver enough impact energy. Start with excavator operating weight, then check the recommended carrier range for each model.
Why Vazão de óleo and Pressure Matter
Hydraulic breakers depend on stable oil flow and operating pressure. If flow is too low, impact rate drops. If pressure is outside the recommended range, seals, hoses and internal components can wear faster.
Choosing Side, Box or Top Type Housing
Box type breakers reduce noise and protect the main body. Side type breakers are easy to service. Top type breakers offer good visibility and positioning for general construction work.
