1. The Engine of Power: Unmatched Force for Every Task

• The SB/GCB Series:​ From the compact SB10 / GCB30​ to the colossal SB151 / GCB400, this series covers excavators from 1 to 40+ tons, offering a perfect balance of power and versatility for general demolition, trenching, and secondary breaking.
• The MS/GHB Series (MS550 to MS800):​ Engineered for high-frequency, high-efficiency performance, these models deliver relentless power for concrete demolition and rock breaking where speed is critical.
• The Heavy-Duty Specialists (HB-G & MB Series):​ Including the HB30G / GCB300​ and HB40G / GCB330, these breakers are built for extreme conditions, offering superior impact energy for quarrying and primary rock breaking.
• The Ultra-Heavy-Duty Line:​ For the most demanding mining and mega-demolition projects, we manufacture breakers compatible with chisel diameters of 175mm, 195mm, 200mm, 205mm, 210mm. Models like the MB1500 / NB1500​ are testaments to our capability to build the industry's most powerful tools.

2. The Science of Precision: Intelligence in Every Impact

• Automatic Frequency Conversion Technology:​ Our intelligent breakers can self-adjust their impact rate based on the material hardness. This isn't just about power; it's about optimal energy transfer. It prevents "blank firing," reduces unnecessary wear on the breaker and excavator, and significantly lowers fuel consumption—a direct response to the industry's search for "fuel-efficient construction equipment."
• Pure Hydraulic System Design:​ By eliminating complex pneumatic or nitrogen pre-charge dependencies in key models, our pure hydraulic design ensures consistent, controllable power delivery. It translates to faster, more predictable breakage, less vibration transmission to the carrier, and a simpler, more robust system that is easier to maintain.

3. Durability: The Foundation of Reliable Performance

• Advanced Material Science:​ The use of high-grade, heat-treated alloy steels in critical components like the housing, piston, and front head.
• Sealed & Protected Design:​ Superior sealing technology guards against contamination, the number one cause of hydraulic system failure, ensuring longevity even in dusty or wet environments.
• Rigorous Testing:​ Every model undergoes a stringent testing protocol that simulates real-world high-load cycles, ensuring they perform reliably from the first day on your job site to the last.
