Doosan DXB130H and DXB190H hydraulic breakers feature an energy recovery system that increases strike power for maximum productivity, the company says.
The nitrogen-powered breakers are equipped with an upper/lower suspension system that isolates the power unit from the housing. Delivering up to 600 blows per minute, the 2,822-pound DXB130H is designed for use with excavators in the 15- to 22-metric-ton weight range, specifically the Doosan DX180LC, DX190W, and DX210W. The 3,698-pound DXB190H is designed for use with excavators in the 21- to 31-metric-ton weight range, which includes the DX225LC, DX235LCR, DX255LC, and DX300LC Doosan excavators
