ME400

Our hydraulic breaker (model 40) combines compact dimensions (910 mm length, 95 kg weight) with optimized hydraulic performance (15-25 L/min oil flow, 90-120 kg/cm² working pressure), making it a perfect fit for 0.8-2.5 ton carriers. It is built with hardened, shock-resistant components, including durable through bolts, easy-to-maintain valve components, and a stable accumulator system, delivering efficient rock-breaking power through a high-energy transfer piston and a specially heat-treated chisel. The reinforced front head and precision hydraulic cylinder further ensure low vibration, long service life, and reliable operation, making it an ideal and cost-effective choice for light-to-medium construction and demolition projects.

🛡️ High-Strength Through-Bolt Technology

The ME400 hydraulic breaker features high-strength, hardened through bolts designed specifically to prevent accidental breakage under extreme mechanical stress. This robust structural reinforcement effectively protects the breaker body from intense vibration and impact during high-frequency operation, ensuring long-term durability and structural integrity on the most demanding job sites.

⚙️ Precision Valve Components for Easy Maintenance

Our advanced valve components ensure smooth and precise reciprocating movement of the piston at optimal frequency. This sophisticated control system not only responds quickly but is also designed for simplified maintenance. By preventing cylinder deformation and maintaining stable hydraulic flow, it significantly reduces downtime and extends the overall service life of the equipment.

🔋 Advanced Accumulator Pressure Compensation

The ME400 is equipped with a high-performance accumulator that effectively compensates for pressure fluctuations within the hydraulic circuit. This prevents harmful pulsations from reaching the excavator's hydraulic pump, ensuring consistent impact force. The low-maintenance design typically requires only nitrogen replenishment, 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 a total weight of only 80 kg, this precision-engineered cylinder controls piston movement with extreme accuracy, delivering high-energy impact comparable to larger excavator attachments.

⚡ Efficient Piston Impact Energy

The precision-machined piston is the power source of the ME400, efficiently converting hydraulic energy into powerful hammering force. By optimizing direct energy transfer to the chisel, it delivers superior rock-breaking performance. This efficiency allows operators to achieve demolition results faster while maintaining lower fuel consumption for the host machine.

🏗️ Rugged Front Head and Shock-Absorbing Structure

The heavy-duty front head provides essential support for the entire breaker assembly and is integrated with premium thrust rings and bushings. This special structure is designed to absorb intense vertical and lateral vibration, effectively isolating the main cylinder from recoil impact and protecting internal components from premature wear.

⛏️ Specially Heat-Treated 40 mm Chisel

The ME400 uses a 40 mm diameter tool made from high-quality alloy steel and subjected to rigorous heat treatment. This process ensures superior surface hardness for rock breaking and a tough core resistant to breakage. Operators can choose from Moil Point, Wedge, or Blunt tool types to perfectly match their specific application requirements.

🏆 ME400 Performance Summary: The Combination of Function and Portability

The ME400 hydraulic breaker represents the ultimate balance of lightweight portability and industrial-grade power. With an 80 kg operating weight and a 40 mm chisel, it is specifically optimized for mini excavators. It provides professional contractors who need powerful breaking force without heavy machinery with a reliable, low-maintenance solution, ensuring maximum uptime and superior efficiency.

🌍 Extensive Applications and Use Scenarios

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