Eco-Friendly Rubber Tyred Gantry Crane with Energy-Saving Technology
Introduction
A rubber tyred gantry crane (RTG crane) is a highly versatile and efficient piece of equipment widely used in ports, container terminals, rail yards, and large logistics centers. It is specifically designed for container handling operations, offering flexibility, mobility, and reliability in stacking and transferring containers. Unlike rail-mounted gantry cranes, a rubber tyred gantry crane runs on durable rubber tires, which allows it to move freely across different surfaces such as concrete, asphalt, or even compacted ground without being confined to fixed tracks. This mobility makes the RTG crane an ideal solution for facilities that require flexible container handling across wide areas.
The structure of a rubber tyred gantry crane is usually a U-shaped steel frame with a trolley and hoisting mechanism running along the gantry beam. It can lift containers of standard sizes—20ft, 40ft, or 45ft—using specialized spreaders, and efficiently stack them up to 6 or 7 rows high. The crane is equipped with advanced drive systems, commonly powered by diesel generators or electric power through hybrid solutions. Modern RTG cranes are often fitted with frequency converters, energy recovery technology, and intelligent control systems to ensure smooth operation, energy savings, and reduced carbon emissions, aligning with the demand for green port development.
A key advantage of rubber tyred gantry cranes lies in their advanced control and automation features. With anti-sway technology, precise positioning systems, and optional remote-control operation, RTG cranes significantly improve safety and handling efficiency. Automated models can perform unmanned stacking and path planning, reducing labor intensity and operational risks.
In terms of applications, RTG cranes are indispensable in container terminals and intermodal yards, where they handle the horizontal transfer and vertical stacking of containers, ensuring fast turnaround times for vessels, trucks, and trains. Their adaptability, strong load capacity, and intelligent operation make rubber tyred gantry cranes a cost-effective and future-ready solution for the modern logistics industry.
Advantages

♦Efficiency in Operations: A rubber tyred gantry crane can work in manual or automated mode, reducing handling time and labor requirements. It is also compatible with container spreaders and other specialized attachments, which improve efficiency during loading and unloading.
♦Cost-Effectiveness: By eliminating the need for additional handling equipment, the rubber tyred gantry crane offers a cost-effective solution for container movement and storage. Its reliability and versatility make it a preferred choice for logistics and shipping companies worldwide.
How Does a Rubber Tyred Gantry Crane Work?
A rubber tyred gantry crane (RTG crane) is a versatile and mobile lifting machine widely used in ports, container yards, and terminals for efficient cargo handling. Unlike rail-mounted cranes, an RTG crane relies on durable rubber tires instead of fixed tracks, giving it greater flexibility, cost-effectiveness, and ease of relocation across different work areas. Built with a rigid gantry frame that houses the main hoist and lifting mechanism, the RTG crane is designed to handle heavy containers and intermodal units with precision.
When a vessel or truck arrives at a terminal, the RTG crane can travel directly to the cargo location. Its heavy-duty rubber wheels allow it to move smoothly over diverse surfaces, including dock pavement, concrete yards, and even across railway tracks. This high maneuverability ensures that the RTG crane can quickly adapt to changing work conditions, reducing downtime and improving operational efficiency.
A key operational advantage of the rubber tyred gantry crane is its advanced steering capability. The crane can rotate, align with container stacks, and navigate tight spaces with stability. Equipped with reliable steering and braking systems, the RTG crane ensures safe lifting and movement of containers even in busy terminals.
The lifting process is powered by electric or hydraulic systems, which drive the hoist to raise, lower, and transport heavy loads. With features such as smooth hoisting, anti-sway control, and precise positioning, the RTG crane guarantees efficient container stacking and retrieval operations.
In conclusion, the rubber tyred gantry crane is indispensable in modern logistics and shipping. Its combination of mobility, flexibility, and lifting efficiency makes the RTG crane a critical asset for ports and terminals, ensuring fast, safe, and cost-effective cargo handling across the global supply chain.
