The SB121 hydraulic hammer, equipped with a 155 mm chisel, is a heavy-duty excavator attachment designed for demanding tasks such as rock breaking, concrete demolition, quarrying, mining, and construction. Featuring a robust housing, reinforced side plates, and a professional-grade hydraulic design, the SB121 harnesses the excavator’s hydraulic power to perform controlled operations in challenging conditions.
The 155 mm chisel configuration is engineered for breaking through hard materials that require deep penetration, effective impact transfer, and operational stability. It is well-suited for primary rock breaking, secondary demolition, foundation excavation, road construction, and the reduction of large blocks of stone or concrete.
155 mm Chisel for Rock and Concrete
The 155 mm chisel is designed to transmit impact energy to rock, concrete, and other hard materials. It can be used for the following applications:
Breaking rock in quarries and mines
Road and highway construction
Excavation for foundations and basements
Demolition of concrete walls, slabs, and footings
Reducing large stone blocks
Trenching and underground utility installation
Secondary demolition and processing of debris for recycling
Depending on the material and working conditions, various tool options may be available. The choice of chisel should be determined based on the hardness of the material, the working depth, and the hydraulic performance of the excavator.
Complete Set Supply
We provide a complete set configuration tailored to the specific excavator model and project requirements. Depending on the order specifications, the complete set may include the hydraulic hammer body, a 155 mm chisel, an excavator mounting bracket, hydraulic hoses, fittings, and the necessary installation accessories.
The mounting bracket and hydraulic piping must be configured according to the exact excavator model. This facilitates both the initial installation and the process of switching between a bucket and the hydraulic hammer.
Installation and Compatibility
The SB121 should not be selected based solely on the excavator’s tonnage. Final compatibility must be confirmed using the following data:
Excavator make and model
Excavator operating weight
Hydraulic flow rate
Hydraulic operating pressure
Requirements for the single-acting auxiliary circuit
Pin diameter
Center-to-center distance between pins
Inside width of the mounting lugs
Hose length and fitting sizes
Requirement for an independent return line
With this information, we prepare the appropriate mounting bracket, hydraulic piping, and installation configuration.
Why Choose US?
The hydraulic cylinder is manufactured from 20CrMo steel for improved strength and durability. The through bolts are made of 42CrMo steel and undergo strict heat treatment to enhance their tensile strength and resistance to deformation.
The hydraulic breaker bushings are also produced from 42CrMo steel with heat treatment, providing reliable wear resistance under heavy-duty impact conditions. The breaker is equipped with high-temperature-resistant oil seals to support stable operation in demanding working environments.
Selected replacement parts are compatible with the Soosan SB121 hydraulic breaker, helping simplify maintenance and reduce spare-parts sourcing difficulties.
Jinan Changhao is a professional manufacturer of hydraulic hammers and excavator attachments designed for construction, quarrying, mining, demolition, and recycling applications. The company offers excavator-specific configurations, custom mounting brackets, hydraulic piping selection, and OEM services.
When requesting a complete SB121 hammer package, please provide the excavator model, operating weight, hydraulic specifications, and mounting dimensions. We will then be able to recommend the appropriate configuration and the necessary installation accessories.
