Advanced Technical Specifications and Design Features
The Dual-Trolley STS Cranes feature impressive dimensional specifications that enable optimal performance in busy terminal environments. With a substantial rail gauge of 35 meters, these cranes provide exceptional stability and operational range. The front outreach extends 73 meters, while the back reach measures 22 meters, allowing for comprehensive coverage of vessel and yard operations.
Hoisting capabilities include 55 meters above rail level and 23 meters below, providing the flexibility needed to handle the largest container vessels currently in service. The trolley travel distances are precisely engineered at 26.5 meters on the seaside and 26.7 meters on the landside, ensuring smooth and efficient container transfer operations.
The through-type structure design represents a significant engineering advancement, enabling seamless coordination between the main trolley and the gantry trolley. This innovative configuration allows for simultaneous operations that dramatically improve overall terminal productivity and operational efficiency.
Intelligent Automation and Control Systems
The advanced automation control systems integrated into the Dual-Trolley STS Cranes represent a technological leap forward in port equipment intelligence. Sophisticated coordination between the main trolley and gantry trolley enables unprecedented operational synchronization, reducing cycle times and enhancing overall terminal throughput capacity.
A comprehensive network of over ten high-precision scanners and more than fifty high-definition cameras creates a detailed 3D perception environment. This extensive sensor array provides real-time data that enables precise container positioning and intelligent handling capabilities, significantly reducing the potential for operational errors.
The smart control system continuously calculates optimal trolley movement paths, taking into account multiple variables including container weight, position, and operational priorities. This intelligent path optimization greatly improves operational efficiency while minimizing energy consumption and equipment wear.

Comprehensive Terminal Equipment Solution
Complementing the advanced Dual-Trolley STS Cranes, a fleet of ten Rubber-Tired Gantry cranes (RGTs) has been simultaneously dispatched to the customer’s terminal facility. These RGTs feature a rated lifting capacity of 41 tons, a span of 23.37 meters, and a lifting height of 18.2 meters, creating a comprehensive container handling solution for yard operations.
The coordinated deployment of both STS cranes and RGTs enables seamless container transfer from vessel to yard, optimizing terminal workflow and maximizing operational efficiency. This integrated equipment approach represents SANY’s commitment to providing complete terminal solutions rather than individual equipment pieces.
The RGTs are engineered to work in perfect synchronization with the Dual-Trolley STS Cranes, featuring compatible control systems and operational interfaces. This equipment harmony ensures smooth container flow throughout the terminal, from vessel unloading through to final yard positioning and storage management.
Advanced Manufacturing Capabilities
SANY Marine operates a state-of-the-art equipment assembly base spanning an impressive 500,000 square meters, demonstrating the company’s substantial manufacturing capacity and technical capabilities. This extensive facility can simultaneously accommodate the assembly and commissioning of 24 STS cranes and 40 RTG cranes, enabling highly efficient production and delivery schedules.
The massive assembly base incorporates advanced manufacturing technologies, including automated welding systems, precision machining equipment, and comprehensive testing facilities. These capabilities ensure that every Dual-Trolley STS Crane meets the highest quality standards and performance requirements before shipment to customer locations.
Strategic facility layout and optimized production processes allow SANY Marine to maintain competitive delivery timelines while ensuring meticulous attention to quality control and technical excellence. This manufacturing prowess positions SANY as a global leader in port equipment production and innovation.
Intelligent Perception and Safety Systems
The comprehensive 3D perception network integrated into the Dual-Trolley STS Cranes represents a technological breakthrough in port equipment safety and operational precision. More than 50 high-definition cameras provide complete visual coverage of all operational areas, while ten high-precision scanners deliver accurate spatial data for intelligent decision-making.
Advanced object detection and collision avoidance systems continuously monitor the operational environment, automatically adjusting crane movements to prevent accidents and ensure operational safety. These intelligent safety features are particularly valuable in busy terminal environments where multiple equipment pieces operate simultaneously.
Real-time data analytics and predictive maintenance capabilities monitor equipment health and performance parameters, identifying potential issues before they develop into significant problems. This proactive approach to maintenance maximizes equipment availability while minimizing unexpected downtime and repair costs.
Operational Benefits and Efficiency Gains
The implementation of Dual-Trolley STS Cranes delivers substantial operational benefits that directly impact terminal productivity and profitability. The dual-trolley system enables simultaneous container handling operations that can reduce vessel turnaround times by up to 30 percent compared to conventional single-trolley systems, providing significant competitive advantages in today’s fast-paced shipping industry.
Advanced automation features reduce labor requirements while enhancing operational precision and consistency. The intelligent control systems optimize every aspect of crane operation, from movement paths to acceleration profiles, ensuring maximum efficiency while minimizing energy consumption and equipment stress.
The sophisticated Dual-Trolley STS Cranes represent a long-term investment in terminal infrastructure that will deliver ongoing operational benefits throughout their service life. Reduced maintenance requirements, enhanced reliability, and adaptable automation capabilities ensure that these cranes will continue to meet evolving terminal requirements for years to come.
