ME400

Our hydraulic breaker (Model 40) combines compact dimensions (910 mm in length, 95 kg in weight) with optimized hydraulic performance (15-25 l/min oil flow, 90-120 kg/cm² operating pressure) to perfectly suit 0.8-2.5 ton carriers. Built with hardened, shock-resistant components—including a durable through bolt, easy-maintenance valve assembly, and stable accumulator system—it delivers efficient rock-breaking power via a high-energy conversion piston and a heat-treated, application-specific chisel. The reinforced front head and precision hydraulic cylinder further ensure low vibration, long service life, and reliable operation, making it an ideal, cost-effective choice for light to medium-duty construction and demolition projects.

🛡️ High-Strength Through Bolt Technology

The ME400 hydraulic breaker is engineered with high-strength, hardened through bolts that are specifically designed to prevent accidental cracking under extreme mechanical stress. This robust structural reinforcement effectively protects the breaker body from intense vibration and shock during high-frequency operation, ensuring long-term durability and structural integrity in the most demanding job sites.

⚙️ Precision Valve Assembly for Easy Maintenance

Our advanced valve assembly ensures the smooth and precise reciprocating motion of the piston at optimal frequencies. This sophisticated control system is not only highly responsive but also designed for simplified maintenance. By preventing oil cylinder deformation and maintaining stable hydraulic flow, it significantly reduces downtime and extends the overall service life of the equipment.

🔋 Advanced Accumulator Pressure Compensation

Equipped with a high-performance accumulator, the ME400 effectively compensates for pressure fluctuations within the hydraulic circuit. This prevents harmful pulsations from reaching the excavator's hydraulic pump, ensuring consistent striking power. The low-maintenance design typically requires only N2-gas refills, providing a reliable power boost for continuous heavy-duty breaking.

🔄 Optimized Hydraulic Cylinder Core

As the heart of the breaker, the ME400’s cylinder features an optimized hydraulic circulation system that minimizes internal friction and energy loss. Despite its compact 80KG total weight, this precision-engineered cylinder controls the piston's movement with extreme accuracy, delivering a high-energy punch that rivals much larger excavator attachments.

⚡ High-Efficiency Piston Impact Energy

The precision-machined piston is the powerhouse of the ME400, efficiently converting hydraulic energy into powerful hammering force. By optimizing the energy transmission directly to the chisel, it delivers superior rock-breaking performance. This efficiency allows operators to achieve faster demolition results while maintaining lower fuel consumption on the primary machine.

🏗️ Robust Front Head & Shock-Absorbing Structure

The heavy-duty front head provides essential support for the entire breaker assembly and is integrated with high-grade thrust rings and bushings. This specialized construction is designed to absorb intense vertical and lateral vibrations, effectively insulating the main cylinder from counter-shocks and protecting the internal components from premature wear and tear.

⛏️ Specially Heat-Treated 40mm Chisel

The ME400 features a 40mm diameter tool made from premium alloy steel that has undergone rigorous heat treatment. This process ensures exceptional surface hardness for breaking rocks and a tough core to resist snapping. Operators can choose from Moil Point, Wedge, or Blunt tool types to perfectly match their specific application requirements.

🏆 ME400 Performance Summary: Power Meets Portability

The ME400 Hydraulic Breaker represents the ultimate balance of lightweight portability and industrial-strength power. With an 80KG operating weight and a 40mm chisel, it is specifically optimized for mini-excavators. It offers a reliable, low-maintenance solution for professional contractors who require a powerful breaking force without the bulk of heavy machinery, ensuring maximum uptime and exceptional efficiency.

🌍 Versatile Application & Usage Scenarios

This 80KG-class breaker is ideal for a wide range of professional environments, including urban infrastructure renovation, residential demolition, and utility trenching. Its compact size makes it particularly effective for working in confined spaces, indoor demolition projects, and landscaping. Whether you are removing concrete sidewalks, breaking frozen ground, or scaling rocks in small quarries, the ME400 delivers consistent performance every time.
