Hydraulic breaker for 5 ton excavator
Hardened Through Bolt for Shock Resistance
The through bolt is made of hardened material to prevent accidental cracking, with a specialized design that effectively shields the breaker from heavy impact shocks, ensuring stable operation under intense rock-breaking conditions.
Easy-Maintenance Valve Assembly
The valve assembly features a user-friendly structure that simplifies routine maintenance, effectively preventing oil cylinder deformation and extending the service life of core hydraulic components.
Stable Nitrogen-Charged Accumulator
The accumulator assembly compensates for pressure fluctuations in the hydraulic circuit and eliminates vibration, operating reliably with only nitrogen gas—no frequent refills are required, reducing operational complexity and downtime.
The ME SB30-53 hydraulic breaker is a robust, high-performance attachment designed for heavy-duty construction and demolition tasks. Built with hardened, shock-resistant components—including a durable through bolt, easy-maintenance valve assembly, and stable nitrogen-charged accumulator—it delivers efficient rock-breaking power via a high-energy conversion piston and a versatile heat-treated chisel. The reinforced front head further minimizes vibration and enhances operational stability, while its optimized hydraulic parameters (20-50 L/min flow, 90-120 kg/cm² pressure) and 161 kg weight make it perfectly suited for 2.5-4 ton carriers. Backed by strict quality assurance and factory-direct pricing, the SB30-53 combines reliable performance and cost-effectiveness, making it an ideal choice for contractors seeking a durable, high-value hydraulic breaker solution.
High-Efficiency Piston Energy Conversion
The piston efficiently converts kinetic energy into powerful impact force, which is directly transmitted to the chisel to break rock with exceptional speed and effectiveness, boosting work productivity.
Vibration-Dampening Front Head Support
The front head provides full structural support for the entire breaker, equipped with a thrust ring and bushing to absorb chisel vibrations, minimizing operational shake and ensuring smooth, stable performance.
Versatile Heat-Treated Chisel Options
The specially heat-treated chisel offers exceptional wear resistance, and can be customized into moil, blunt, or wedge types to adapt to diverse rock-breaking and demolition applications.
Optimized Hydraulic Performance for 2.5-4 Ton Carriers
With an operating flow of 20-50 L/min and operating pressure of 90-120 kg/cm², this breaker delivers precise, powerful performance perfectly matched to 2.5-4 ton carriers, ensuring seamless integration and efficient operation.
Premium Quality & Factory-Direct Affordability
This breaker is manufactured under strict quality control standards, using durable materials to guarantee long-term reliability. We offer direct factory pricing with no middleman markup, delivering exceptional value—top-tier performance at a cost-effective price.
