Modern double cylinder hydraulic shears integrate sophisticated hydraulics and materials to achieve exceptional performance. The dual high-pressure cylinders work in tandem, providing synchronized force that prevents jaw twisting and ensures clean, powerful cuts.
• Balanced Dual-Cylinder System: Distributes pressure evenly across jaws for higher cutting force and reduced stress on components during metal cutting tool for excavators operations.
• Advanced Speed Valves: Accelerate non-loaded jaw movements while delivering full power on contact, shortening cycle times significantly in high-volume industrial scrap recycling.
• Premium Wear-Resistant Materials: Jaws and blades crafted from high-strength alloys (often HARDOX-equivalent or similar) with double-layer protection for extended service life under abrasive conditions.
• Full 360 Degree Rotation Shear: Hydraulic motor-driven rotation allows precise positioning in tight or complex sites without constant excavator repositioning.
• Overload Protection and Modular Design: Built-in safeguards prevent damage, while modular components simplify repairs and upgrades.
• Efficient Hydraulic Integration: Optimized for standard excavator flows, with dustproof seals and automatic idling features to minimize energy waste.
Changyu Machinery emphasizes these elements in their hydraulic double cylinder shear lineup, creating robust multi-processor excavator attachments that deliver consistent results in harsh environments.
