Gantry crane
Weiyuan Rail-Mounted Port Container Gantry Crane (RMG)

Product Overview
The Weiyuan Rail-Mounted Double Girder Port Container Gantry Crane (RMG) is a high-performance lifting solution engineered specifically for the rigorous demands of modern container terminals and intermodal yards. With a robust lifting capacity of 50 tons and beyond, this crane excels at high-speed, high-volume container handling. Its rail-mounted design ensures precise, stable movement over long runways, making it the backbone of efficient container stacking and transfer operations. Equipped with a specialized container spreader and advanced control systems, the Weiyuan RMG crane is built to maximize throughput, optimize yard space, and ensure operational safety.
Product Advantages
- High-Speed Productivity: Engineered for rapid acceleration and high traveling speeds, this crane significantly reduces cycle times for loading, unloading, and stacking containers, boosting terminal throughput.
- Exceptional Stability and Precision: The rail-mounted design provides a fixed, stable path, eliminating sway and enabling precise, repeatable container positioning, which is critical for dense stacking and automated operations.
- Maximized Yard Utilization: By operating over multiple container rows and truck lanes, the RMG crane allows for high-density stacking, making the most of your valuable terminal or yard space.
- Heavy-Duty Reliability: Built with a durable double-girder structure and high-quality components, this crane is designed for 24/7 operation in harsh port environments, ensuring maximum uptime and a long service life.
- Advanced Automation and Safety: Can be equipped with advanced features such as anti-sway technology, automated positioning systems, and comprehensive safety monitoring to enhance both efficiency and operator safety.
Application Scenarios
- Seaport Container Terminals: The primary application for loading containers on and off vessels, transferring them to trucks or trains, and organizing container stacks in the yard.
- Intermodal Rail Yards: Essential for efficiently transferring containers between railway cars and trucks, facilitating the smooth flow of goods.
- Large-Scale Logistics Hubs: Ideal for managing large volumes of container traffic in major distribution and storage centers.
- Inland Container Depots: Provides efficient container handling and storage solutions away from maritime ports, serving as a critical link in the supply chain.

FAQ
1. What is the difference between a Rail-Mounted Gantry (RMG) crane and a Rubber-Tired Gantry (RTG) crane?
An RMG runs on fixed rails, offering higher speed and stability, making it ideal for high-volume, automated, or semi-automated terminals. An RTG runs on rubber tires, providing more flexibility to move between container blocks but is generally slower and requires a driver for each move.
2. Can the RMG crane handle different container sizes?
Yes. It is equipped with a telescopic spreader that can be adjusted to handle standard container sizes, including 20ft, 40ft, and 45ft. Twin-lift spreaders for handling two 20ft containers at once are also available.
3. What site preparation is needed for an RMG crane?
The main requirement is the installation of robust crane rails on a reinforced concrete foundation capable of supporting the crane’s weight and the dynamic loads during operation. We provide detailed foundation and rail specifications.
4. Is automation possible with this crane?
Absolutely. RMG cranes are perfectly suited for semi- or fully-automated operation. We can integrate systems for automated steering, container positioning, and remote operation to maximize efficiency and reduce labor costs.
5. How does this crane perform in high winds, typical of port environments?
The crane is designed to operate safely within specified wind speed limits. It is equipped with anemometers to monitor wind speed and features robust rail clamps or storm anchors that securely lock the crane to the rails during out-of-service conditions or severe weather.
