The new DXB130H and DXB190H (pictured) hydraulic breakers from Doosan feature an energy recovery system designed to increase strike power. 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. The 3,698-pound DXB190H is designed for use with excavators in the 21-to-31 metric ton range. The engine recovery system captures the piston’s rebound energy to increase strike power. The cradle-mounted grease station delivers continuous grease flow, reducing bushing and tool wear. www.doosaninfracore.com
