Twin Shaft Cutter (TSC) Hydraulic Cylinder
Product Description
Twin Shaft Cutter (TSC) Hydraulic Cylinder
Product Description
The Twin Shaft Cutter (TSC) Hydraulic Cylinder is a high-performance actuator engineered for precision control in underground trenching and hard-rock milling operations. Designed as a critical component of advanced diaphragm wall construction equipment, this cylinder ensures reliable power transmission and precise feed control in challenging environments. Built with high-strength alloy steel and advanced sealing technologies, it withstands pressures up to 35 MPa and abrasive conditions, making it ideal for deep excavations (up to 120 m) and hard-rock formations.
Key Specifications
Bore Diameter: 140–350 mm
Rod Diameter: 90–230 mm
Stroke Length: Customizable up to 8,500 mm
Operating Pressure: 35 MPa
Temperature Range: -30°C to +120°C (optional variants available)
Core Advantages
Robust Construction: Reinforced piston rods and corrosion-resistant coatings (e.g., hard chrome plating) enhance durability in abrasive soil and mud environments.
Precision Control: Patented differential pulley and drum systems enable smooth feed adjustments, minimizing power loss and optimizing milling efficiency.
Environmental Adaptability: Multi-layered sealing systems with waterproof and dustproof designs ensure long-term reliability in humid or high-contamination conditions.
Low Maintenance: Modular design with standardized flange interfaces allows for quick disassembly and replacement, reducing downtime by up to 40%.
Customization: Supports tailored mounting configurations (e.g., trunnion, clevis, or flange) and integration with automated control systems for enhanced operational flexibility.
Applications
Deep Foundation Engineering: Ensures stable milling in metro station diaphragm walls and dam cutoff trenches.
Urban Infrastructure: Ideal for confined-space projects requiring minimal vibration and noise pollution.
Mining & Tunneling: Optimizes efficiency in hard-rock excavation with controlled feed rates (40–60 cm/h in 100 MPa hardness rock).
Industry Validation
Developed in collaboration with leading manufacturers like XCMG and Zoomlion, this cylinder incorporates innovations such as anti-bias load structures and self-lubricating bushings, setting benchmarks for performance and longevity in global infrastructure projects.
