In today’s rapidly growing global trade environment, the demand for efficient material handling equipment in the logistics and industrial sectors is becoming increasingly urgent. According to relevant data, global cargo trade volume has been steadily increasing in recent years, leading to a significant rise in cargo throughput at ports, logistics centers, and other facilities. As an important material handling device, the rubber tyred gantry crane (RTGC) has established a pivotal role across various industries—including ports, foundries, bridge construction, external logistics and warehousing, wind energy, power plants, and steel mills—thanks to its efficiency, flexibility, and mobility.
The Importance of Automation Trends
Traditional rubber tyred gantry cranes have numerous shortcomings in terms of reliance on human labor, operational efficiency, precision control, and energy consumption and pollution. As the modernization process accelerates across industries, automation has become an inevitable trend for rubber gantry cranes to break through development bottlenecks. Automation not only significantly improves operational efficiency and reduces operational costs but also enhances operational safety and precision, better adapting to complex and dynamic operational scenarios. Therefore, thoroughly exploring its automation trends holds significant practical significance.
What is a rubber tyred gantry crane?
A rubber tyred gantry crane is a large mobile crane that moves on rubber tires and has the ability to flexibly transfer between different sites. Its primary function is to lift, transport, and load/unload various types of cargo, and it is widely used in material handling processes across multiple industries. This crane, with its unique design, demonstrates notable characteristics such as efficiency, flexibility, and mobility, providing strong support for logistics operations across various industries.
Rubber tyred gantry cranes come in a wide variety of types. Among them, single-beam cranes have a relatively simple structure and are suitable for locations with lower lifting capacity requirements and limited operational space; double-girder cranes have greater load-bearing capacity and can handle heavier cargo handling tasks; A-frame cranes, with their unique structural design, offer advantages in stability and lifting height, meeting specific operational requirements under certain conditions. These different types of cranes can fully meet the demands of various complex working conditions.
Automation Trends in Rubber tyred Gantry Cranes
GPS/Beidou Positioning
GPS (Global Positioning System) and Beidou positioning systems play a crucial role in the automation of rubber tyred gantry cranes. In port environments, these positioning systems enable cranes to obtain real-time, precise location information. For example, Xiamen Port has implemented GPS positioning technology on some rubber gantry cranes, allowing them to automatically navigate and accurately dock at designated loading/unloading positions based on positioning data, significantly enhancing operational accuracy and efficiency. In foundries and power plants, positioning systems also help cranes quickly locate the positions of goods to be transported, avoiding time wasted on manual searches.
LiDAR and Visual Navigation
LiDAR scans the surrounding environment to create precise 3D maps, providing rubber tyred gantry cranes with detailed environmental information. Visual cameras identify goods and obstacles, assisting cranes in precise operations. Taicang Port has applied laser radar and visual navigation technology on automated tire cranes. During bridge construction, the crane uses laser radar to sense the surrounding terrain and obstacles, while visual cameras identify the position and shape of bridge components, enabling precise handling and installation of bridge components. In complex environments such as steel mills, this technology helps cranes accurately identify steel materials of different shapes and sizes, improving handling efficiency and safety.
Remote Control System
The remote control system allows operators to control rubber tyred gantry cranes from a control room located away from the worksite. In wind farms, where wind turbines are widely dispersed and the on-site environment is complex, the adoption of a remote control system eliminates the need for operators to work in harsh outdoor conditions. Instead, they can remotely control cranes from a control room using an operating console, thereby enhancing operational safety and comfort. The remote-controlled gantry crane at Meishan Port Area of Ningbo-Zhoushan Port is a typical example. Through the remote control system, operators can monitor the crane’s operational status in real-time and perform precise control, thereby improving operational efficiency. In external logistics scenarios, the remote control system also enables operators to promptly respond to operational demands in different areas and achieve efficient scheduling.
Automatic Loading and Unloading System
Utilizing sensors and algorithms, the automatic loading and unloading system enables the crane hook to automatically grasp and place cargo. In warehouse scenarios, sensors detect information such as the location, shape, and weight of cargo, while algorithms control the movements of the lifting equipment based on this information, enabling precise grasping and placement of cargo, significantly improving loading and unloading efficiency and accuracy. After Tianjin Port Alliance International Container Company implemented automated remote control upgrades for rubber tyred gantry cranes, the automated loading and unloading system played a crucial role in effectively enhancing container loading and unloading efficiency while reducing labor costs. In steel mills, the automated loading and unloading system can quickly and accurately handle steel materials of various specifications, improving the continuity of production processes.
Mechanical Anti-Sway Optimization
By optimizing mechanical anti-sway mechanisms, such as adjusting the angle of steel wires, the anti-sway functionality of rubber tyred gantry cranes in the travel direction can be enhanced. In scenarios like bridge construction and heavy cargo handling, where cargo is large in weight and volume, swaying is more likely to occur. During the renovation of tire cranes at Taicang Port, the mechanical anti-sway mechanism was optimized by reasonably adjusting the length and angle of the steel wires, reducing swaying during cargo handling and improving operational stability and safety. When handling large bridge components, the optimized mechanical anti-sway mechanism ensures smooth lifting of the components, providing assurance for subsequent installation work.
Electronic Anti-Sway Technology
Electronic anti-sway technology utilizes open-loop and closed-loop intelligent control to minimize the swing amplitude of the lifting equipment, ensuring stable automated operations. This technology is particularly critical in scenarios such as wind energy equipment handling and power plant cargo loading/unloading. For example, when handling wind turbine blades, due to their long length, they are prone to swaying due to factors like wind force. The electronic anti-sway system can monitor the swinging of the lifting device in real-time and adjust the crane’s operating parameters through intelligent algorithms to quickly suppress swaying, ensuring the safe handling of the blades. In power plant operations involving the loading and unloading of large equipment, electronic anti-sway technology also effectively ensures the precision and stability of operations.
