“The key to fitting the right hammer to the machine is a test with a flow meter to make sure the hydraulic flow pressure matches the capabilities of the hammers, ” says Tedesco.

“To maximize the life and efficiency of a hydraulic hammer while putting as little strain on the hydraulic system as possible, the carrier must be set up to deliver oil to the hydraulic breaker at the correct volume, pressure, and relief without exceeding the backpressure limitations of the hammer.

“Too much oil or pressure will cause the hammer to overspeed, which reduces seal life and can damage internal components, ” he says. “Improperly set relief or excessive backpressure can cause the breaker to overheat and transfer heat to the carrier’s hydraulic system. Too little oil flow reduces the breaker’s impact power. Additionally, too little oil flow won’t provide the necessary lubricating film between internal moving parts and lead to damage. ”

According to Joel Escalante, senior product specialist, Doosan Infracore North America, “The proper rule of thumb for excavator/breaker matching is to ensure one pump flow. For instance, if the maximum flow on an excavator is 2 x 50 gpm = total of 100 gpm, the maximum flow requirement by the breaker should not exceed 50 gpm. In other words, if the flow required is 60 gpm, you must use a bigger excavator or reduce the size of the breaker. ”

“Most carriers have adjustable hydraulic systems to perform this fine-tuning, ” Tedesco says, “but a qualified hydraulic technician with the proper flow meter to measure all of the hydraulic values simultaneously throughout the operating range is the only way to optimize your hydraulic breaker’s performance and protect your carrier. ”
