Unleash the Versatility of the SB40 Rock Breaker
For contractors working in urban environments or tight jobsites, the SB40 Hydraulic Breaker is the definitive choice. Engineered specifically for 6 to 9-ton mini and midi excavators, the SB40 offers a high power-to-weight ratio that transforms your compact machine into a demolition specialist.
At Maoyt , we’ve refined the SB40 to deliver rapid-fire impacts, making it perfect for breaking asphalt, concrete pavements, and frozen ground.
Technical Excellence: Why the SB40 Stands Out
High Blow Frequency (BPM)
Unlike larger models that focus on raw crushing force, the SB40 is tuned for speed. Its high impact rate allows operators to "slice" through concrete and soft rock much faster, significantly increasing hourly production on utility and landscaping projects.
Advanced Piston Design
The SB40 features a long-stroke piston designed to minimize recoil. This not only protects the hammer's internal seals but also reduces the vibration transmitted to the excavator’s arm, extending the life of your carrier machine.
68mm Heavy-Duty Chisel
Standard with a high-tensile 68mm diameter tool, the SB40 provides deep penetration. We offer various tool points (Moil, Wedge, Blunt) to match your specific rock or concrete density.
