STS Quay Cranes: Intelligent Port Handling Solutions

As the core equipment for container loading and unloading at the forefront of modern ports, WEIHUA Ship-to-Shore (STS) Quay Cranes integrate advanced technology, 信頼できるパフォーマンス, and energy-efficient design to deliver exceptional handling efficiency for global port operations. Engineered to meet the diverse needs of container terminals—from small and medium-sized harbors to large-scale automated ports—these cranes redefine productivity and safety in maritime logistics.

Product Overview

WEIHUA STS Quay Cranes (also known as QC Cranes) are specialized lifting systems designed for seamless container transfer between ships, terminal yards, and container trucks. Constructed with high-strength steel structures and precision-engineered mechanisms, they accommodate 20-foot, 40-foot, and 45-foot containers, with dedicated models for Panamax, Post-Panamax, and Super Post-Panamax vessels—including configurations capable of lifting two 40-foot containers simultaneously.

Compliant with international standards such as FEM, から, IEC, AWS, and GB, these cranes undergo rigorous quality control throughout the design, 製造, and inspection processes, ensuring compatibility with global port infrastructures and operational requirements.

Core Technologies & Features

Intelligent Control System

• 1. Multi-mode Operation: Supports manual, semi-automatic, and fully automatic remote operation, enabling seamless integration with automated terminal management systems (TOS/TCS). The automatic mode achieves precise positioning (±15mm GPS accuracy) and intelligent spreader trajectory control for unmanned operation.
• 2. Advanced Automation: Equipped with PLC control and distributed bus technology with optical fiber communication, ensuring anti-interference performance and high operational stability. Optional electronic anti-sway systems minimize container swing, enhancing positioning accuracy.
• 3. Real-time Monitoring: Integrated CMS (Condition Monitoring System) and CMMS (Computerized Maintenance Management System) enable automatic fault detection, real-time data display, and predictive maintenance, ダウンタイムの短縮.

High-Efficiency Performance

• 1. Powerful Lifting Capacity: Ranges from 30.5t to 80t under the spreader (38t to 60t above the spreader), with working duties up to A7-A8 to handle high-frequency loading/unloading.
• 2. Optimized Speed Configuration:
  • Lifting speed: 50-70m/min (full load) and 120-180m/min (no load)
  • Trolley traveling speed: Up to 240m/min
  • Gantry traveling speed: 45m/min
  • One-way boom hoisting time: 5 minutes (80° luffing angle for easy ship berthing).
• 3. Extended Working Range: Front outreach up to 65m, rear outreach up to 25m, and lifting height up to 38m (customizable for deeper vessels and higher stacking needs).

Comprehensive Safety Protection

• 1. Structural & Mechanical Safety: High-strength gantry frame with wind-resistant design, intelligent tilting anti-snag protection, and double braking systems for the lifting mechanism prevent load drops.
• 2. Environmental Adaptability: Operates reliably in temperatures ranging from -25°C to 40°C, with weather-resistant electrical components and emergency stop systems.
• 3. Operational Safeguards: Includes overload protection, limit switches, collision avoidance systems, and well-equipped communication/lighting facilities for safe 24/7 operation.

エネルギー効率 & Sustainability

• 1. Energy-Saving Technologies: Adopts vector frequency conversion, electric energy feedback, and torque balance control, reducing energy consumption by up to 20% compared to conventional cranes.
• 2. Eco-Friendly Design: Low-noise operation, zero-emission electric power (3-phase AC, 380V/50Hz, customizable to local grids), and compatibility with hybrid power systems.
