In the 1,000-ft.-lb. class, the 125SX hydraulic breaker attaches to skid-steer loaders, backhoes, excavators up to 22,000 pounds, and the company's Standard Duty Rockbreaking Systems. The unit recycles rebound energy and adds it to the next blow. A pressure regulator maintains the correct operating pressure. To preserve machine life and limit maintenance time, the hydraulically driven piston requires no gas activation or assistance. Striking rate ranges from 420 to 800 bpm. The hammer accepts 13 to 26 gpm of flow and 1,450 psi operating pressure.
