Twin Shaft Cutter (TSC) Hydraulic Cylinder

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.
