18-26 ton excavator breaker

This ME SB81-140 hydraulic breaker is designed for excavators with a capacity of 18-26 tons. It has a working flow rate of 120-180 L/min, a working pressure of 160-180 kg/cm², and a chisel diameter of 140 mm.

Precision 140MM Tool Diameter for Deep Penetration

Equipped with a 140 MM tool diameter, the breaker offers a wide striking surface for deep rock penetration. The precision-machined chisel interface ensures perfect alignment, maximizing energy transfer and minimizing wear on critical components.

Shock-Resistant Hardened Through Bolt

The through bolt is forged from hardened alloy steel to prevent cracking under extreme impact loads, with a specialized anti-shock design that protects the entire breaker structure from stress damage, ensuring long-term durability in the harshest working conditions.

Stable Nitrogen-Charged Hydraulic System

The nitrogen-charged cylinder and accumulator work in sync to maintain consistent internal pressure, eliminating pressure fluctuations and vibration. This system ensures steady, continuous impact performance even during prolonged operation, with no frequent nitrogen refills required.

Low-Maintenance Valve & Cylinder Design

The valve assembly features an easy-access structure that simplifies routine maintenance, while the precision-engineered cylinder resists deformation under ultra-high pressure. This reduces downtime and repair costs, extending the service life of core hydraulic components.

Vibration-Dampening Front Head & Bushings

The front head, paired with thrust rings and precision bushings, effectively absorbs chisel vibration, reducing operator fatigue and protecting the carrier machine from excessive wear. This results in smoother, quieter operation and improved job site safety.

Premium Quality with Factory-Direct Cost-Effectiveness

Manufactured under strict quality control standards using wear-resistant, industrial-grade materials, the SB81-140 guarantees reliable performance in extreme environments. Direct factory pricing eliminates middleman markup, offering exceptional value for large-scale mining and construction operations.

The ME SB81-140 hydraulic breaker is a top-tier heavy-duty attachment engineered for the most demanding mining, quarrying, and large-scale demolition projects. Boasting an impressive 160-180 KG/CM² operating pressure, 120-180 L/MIN flow rate, and a robust 1800 KG structure, it delivers extreme impact power to tackle the hardest materials. Its precision 140 MM tool diameter, shock-resistant hardened components, and stable nitrogen-charged hydraulic system ensure efficient, reliable performance, while the low-maintenance design and vibration-dampening features enhance durability and operator comfort.
