Description
RB777 concrete pneumatic breaker Main features:
RB777 concrete pneumatic breaker is a tool powered by compressed air. The compressed air is distributed to both ends of the cylinder in turn by the valve, which causes the hammer head to move reciprocally through the pad hammer, impacting the end of the steel shank, which chisels into the concrete layer. The hammer is used to split it into pieces. Durable, with excellent performance, and simple operation, is a classic product in crushing tools. Output power is higher than the same level of products, can crush different hardness ranges of media, and a wide range of applications. The parts are designed with precision technology, and the spare parts have a long service life. RB777 concrete pneumatic breaker can relies on the weight of the body to overcome 80% of the rebound force, comfortable operation.
RB777 air pick an applicable scope
1, Coal mining in coal mines, planning the foot pit of the column, opening the ditch;
2, Mining soft rock;
3, Breaking concrete, permafrost, and ice in construction and installation projects;
Shenglida air jackhammers are used in road construction and building foundation work sites and used to break high-strength concrete.
