The paving breaker B87C utilizes compressed air as its driving force, delivering powerful performance for concrete reinforcement and the efficient breaking of rocks and asphalt. The compressed air is alternately distributed through a precision-designed valve system to both ends of the cylinder assembly, generating a strong reciprocating motion. This motion drives the hammer to strike the shank of the steel chisel via the tappet, effectively driving the chisel into the concrete foundation and splitting it into large sections. Engineered for superior power, efficiency, and durability, this breaker offers an extended service life. It excels in crushing large, thick, and hard materials, making it the ideal tool for demanding foundation construction projects, including mining, bridgework, road construction, and municipal infrastructure development.
