Hard rock breaking is a core step in mining operations and infrastructure demolition. Traditional breaking tools often face rapid abrasion and low efficiency when processing granite and complex mineral structures. The RB777 pneumatic breaker from Kaituo is a compressed air-driven handheld tool designed for heavy-duty breaking tasks. Its percussive system and alloy steel construction support consistent performance in demanding work environments, serving industrial clients in mining, road construction, and foundation engineering.
The RB777 pneumatic pickaxe adopts a compressed air-driven percussive structure. It is equipped with a 57 mm piston and a 189 mm stroke, delivering regular percussive force during operation. Compressed air enters the valve unit through the air connection pipe, and the valve distributes air to drive the piston in reciprocating motion. The piston strikes the end of the steel shank, allowing the bit to penetrate hard materials and break them into fragments. The percussive frequency reaches 18.3 Hz, supporting steady breaking progress on hard rock and reinforced concrete surfaces.
The main components of the RB777 jack hammer are forged from high-strength alloy steel. This material resists abrasion during continuous contact with hard rock and concrete, extending the service life of core parts. The front head features a dedicated structural design, and a removable bushing is installed to protect the front head from wear. The forged latch retainer structure enables quick chisel replacement, reducing interruption time during work shifts.

The RB777 pneumatic crushing pick is suitable for operations in large mines and sites with complex geological conditions. It can process hard granite and complex mineral vein structures, supporting ore extraction and rock fragmentation work. Its pneumatic drive structure adapts to underground and open-pit mining environments, providing consistent breaking capacity for daily mining procedures.
For road construction, municipal engineering, and building foundation projects, the RB777 pneumatic hammer works for breaking hardened concrete and other solid materials. It supports installation works and demolition tasks on construction sites, with a simple structure that allows on-site teams to put it into use by connecting to a compressed air source.
The RB777 pneumatic pickaxe features an ergonomic handle structure that reduces vibration transmitted to the operator’s arms. This design lowers physical fatigue during long work shifts, allowing construction crews to maintain steady working rhythm during extended operation periods.
The RB777 breaker has a simple structural design, which makes inspection and repair procedures accessible for on-site maintenance teams. Its accessories follow universal specifications, and the manufacturer maintains a large stock of spare parts for commercial orders. Users can source replacement parts directly from the factory, reducing maintenance lead time.
