ME680

🛡️ Reinforced Through Bolt Structural Integrity

The ME680 is engineered with high-tensile, hardened through bolts designed to stabilize its 300KG structural frame. This specialized reinforcement prevents accidental cracking and maintains perfect internal alignment during high-intensity operations. By securing the breaker body against extreme vibration, these bolts ensure long-term durability and reduce maintenance costs in challenging work environments.

⚙️ Precision Valve Assembly for Smooth Control

Equipped with a sophisticated internal valve system, the ME680 ensures the precise reciprocating motion of the piston at optimal frequencies. This design manages hydraulic flows of 40-70 L/min effectively, providing responsive control while preventing oil cylinder deformation. The simplified valve structure allows for easier routine inspections and faster maintenance, maximizing your machine's uptime.

🔋 High-Capacity Accumulator Pressure Buffer

The ME680 features an advanced internal accumulator assembly that acts as a crucial buffer to absorb hydraulic pressure spikes. By compensating for pressure fluctuations within the 110-140 KG/cm² circuit, it protects the excavator's hydraulic pump and seals from potential damage. This system ensures consistent striking power while extending the overall service life of your machinery.

⚡ High-Efficiency Kinetic Energy Piston

The ME680 utilizes a precision-machined piston that converts hydraulic energy into powerful kinetic impact with minimal power loss. By matching the stroke perfectly to the 68mm chisel, this system delivers a concentrated punch that shatters rock and concrete efficiently. This high-efficiency design allows for faster material penetration while optimizing the fuel consumption of the carrier excavator.

🔄 High-Stability Precision Cylinder Core

As the core power unit, the ME680 cylinder is crafted with mirror-finish internal bores to minimize friction and heat buildup during extended use. This precision-engineered cylinder ensures the piston operates with maximum accuracy shift after shift. The robust housing further protects the cylinder from external debris, ensuring stable performance during continuous demolition tasks.

🏗️ Shock-Absorbing Front Head & Thrust Support

The heavy-duty front head of the ME680 is designed to provide ultimate support for the 68mm chisel while absorbing intense counter-shocks. Utilizing high-grade thrust rings and vibration-dampening bushings, this structure effectively insulates the main body from harmful feedback. This robust construction significantly reduces wear on internal components, even during aggressive breaking cycles.

⛏️ Specially Heat-Treated 68mm Alloy Chisel

The ME680 comes standard with a premium 68mm diameter alloy steel chisel that has undergone a rigorous multi-stage heat treatment process. This ensures exceptional surface hardness for breaking tough materials while maintaining a resilient core to prevent snapping. Available in multiple point styles, this tool ensures consistent breaking performance across a variety of industrial applications.
