Key Features & Technical Advantages​​

The SB43/GCB75 model incorporates advanced engineering features that set it apart from conventional breakers.

· •​​Optimized Impact Energy (1017 Joules):​​ Delivers a powerful blow for efficient fragmentation of medium-strength concrete and rock, maximizing productivity without overloading the carrier machine.

· •​​Open-Type (Side-Plates) Design:​​ This design allows for better heat dissipation, reduces the risk of casing damage from steel-on-steel contact, and simplifies maintenance and inspection of internal parts.

· •​​Excellent Power-to-Weight Ratio:​​ Weighing only ​​413 kg​​, the hammer is perfectly balanced for 6-9 ton excavators, ensuring stable performance and minimal wear on the carrier's boom and arm.

· •​​Advanced Hydraulic System:​​ Operates efficiently within a wide flow range of ​​50-90 L/min​​ at a working pressure of ​​120-150 bar​​, making it compatible with a variety of excavator models in its class.

•​​Precision Engineering for Longevity:​​ Features like the ​​75mm tool diameter​​ and automatic pressure relief valve protect the hammer from damage caused by blank-firing and excessive pressure spike
