Hydraulic breaker for 4-7 ton excavator
Enhanced Power Output for Medium-Duty Tasks
Boasting 110-140 KG/CM² operating pressure and 40-70 L/min flow rate, this breaker delivers robust impact energy, making it ideal for medium-scale rock breaking, concrete demolition, and excavation projects. It efficiently converts hydraulic power into formidable striking force to tackle tough materials.
Heavy-Duty 300KG Build for Durability
Weighing 300 KG with a reinforced structural design, the breaker offers exceptional mass and stability during operation. This substantial weight ensures consistent breaking power while minimizing machine bounce, enhancing overall control and job site safety.
This ME SB40-68 hydraulic breaker is designed for 4-7 ton excavators. It has a working flow rate of 40-70 liters/minute, a working pressure of 110-140 bar, and an impact frequency of 500-900 impacts/minute, perfectly matching the hydraulic systems of excavators in this tonnage. The chisel has a 68mm diameter and is made of high-strength alloy steel, ensuring excellent durability.
Precision 68MM Tool Diameter
Equipped with a 68 MM tool diameter, the attachment provides optimal striking surface area for efficient rock penetration. The precision-machined chisel seat ensures perfect alignment, reducing wear on critical components and maximizing impact transfer.
Low-Maintenance Hydraulic Core
Featuring a precision-engineered valve assembly and cylinder system, the breaker is designed for easy maintenance. Its robust construction prevents oil cylinder deformation, reducing repair frequency and ensuring long-term reliability with minimal upkeep.
Smooth Vibration Control System
Integrated with a high-performance accumulator and precision bushings, the unit stabilizes hydraulic pressure and dampens vibrations. This results in smoother operation, reduced operator fatigue, and extended service life for both the breaker and carrier machine.
Nitrogen-Assisted System for Consistent Performance
The nitrogen-charged cylinder maintains stable internal pressure, delivering reliable and continuous impact force. This self-regulating system eliminates pressure surges, ensuring steady performance even during prolonged working cycles.
Strict Quality Control with Factory Direct Pricing
Crafted under rigorous manufacturing standards to withstand harsh conditions, the SB40-68 guarantees superior durability and performance. We offer direct factory pricing without intermediary markups, providing exceptional value for professional contractors.
