A rubber tyred gantry crane (RTG crane) is a specialized type of crane designed for lifting and moving various materials and containers in precast yards, manufacturing plants, container terminals, and other logistics facilities. Equipped with rubber tyres, these cranes can travel on paved surfaces within the facility without requiring tracks. Their high mobility and flexibility make them ideal for a wide range of material handling applications.
Main Parts of Rubber Tyred Gantry Cranes
The main components of a rubber-tyred gantry crane typically include the steel frame, hoisting mechanism, slewing mechanism, anti-shaking mechanism, crane traveling mechanism, turning mechanism, trolley traveling mechanism, spreaders, and other essential parts. This section provides detailed information about the various components and functions of the rubber tyre gantry crane.
Steel Frame
The steel frame serves as the structural backbone of the RTG rubber tyred gantry crane, offering essential support and stability for the entire crane.
The steel frame consists of columns, beams, and braces, all designed to withstand the operational loads and environmental conditions encountered by the crane.
The steel frame supports the hoisting mechanism, slewing mechanism, and various other crane components.
It distributes the load from lifting operations and other crane movements to the ground through its columns, beams, and braces.
Hoisting Mechanism
The hoisting mechanism is responsible for lifting and lowering containers or other heavy loads. It is typically mounted on a trolley that travels along the gantry beam.
The hoist motor supplies the necessary power for lifting operations. Wire ropes or chains, wound around a drum connected to the hoist motor, raise or lower the spreaders (such as container spreaders, C-frame lifting spreaders, or other types). The spreaders securely grip the container or other loads, enabling them to be lifted and moved.
Minimum Slewing Mechanism
The minimum slewing mechanism allows the rubber tired gantry crane to rotate horizontally, enabling it to reach containers or specific loading and unloading positions.
The slewing motor drives the rotation, and the slewing gear transmits this rotational force to the upper structure of the crane. This mechanism enables the crane to reach containers or other loads positioned at various locations around its base.
Spreader Anti-Shaking Mechanism
The spreader’s anti-shaking mechanism reduces swinging or shaking of the spreader (container lifting device) during lifting and lowering operations. This system often incorporates hydraulic dampers or stabilizers to ensure smooth and controlled handling of containers.
Crane Travel Mechanism
The crane travel mechanism allows the RTG to move along predefined paths within container yards, prefabricated yards, logistics centers, and other facilities. Drive motors propel the crane’s rubber tyres, while the braking system ensures controlled stopping and precise positioning of the gantry crane.
Turning Mechanism
The turning mechanism enables the tyre mounted gantry crane to make precise turns within confined spaces. Various steering systems and methods, such as straightforward movement, reverse movement, 360-degree rotation, 90-degree steering, Ackerman steering, and others, are employed to accommodate diverse operational requirements.
Trolley Traveling Mechanism
The trolley traveling mechanism moves the hoisting mechanism, including the spreader, horizontally along the gantry beam. This allows for precise positioning of the hoisting mechanism during the handling of heavy loads and containers. Trolley drive motors drive the movement of the trolley, while rails or guides ensure smooth traversal along the gantry beam.
Lifting Devices
The lifting devices, usually the spreader, are crucial for gripping and lifting containers or cargo. The spreader works in coordination with the hoisting mechanism to safely lift and position containers and other heavy materials during loading and unloading operations.
Electrical Equipment
The electrical equipment in an RTG gantry crane comprises control panels, sensors, and wiring necessary for operating its various functions. Power distribution systems ensure electricity is supplied to the crane’s motors and mechanisms.
Other Accessories
Additional accessories and components may include the following items:
Operator cabins provide a control station for crane operators to monitor and control crane operations.
Safety features such as emergency stop buttons, alarms, and monitoring systems ensure safe working conditions.
Diesel generating sets may provide onboard power for crane operations in areas with limited electrical infrastructure.
Telemetry and Communication Systems: Enable remote monitoring and control of crane operations.
Each of these parts and components plays a critical role in the operation and functionality of a rubber tyred gantry crane, ensuring efficient and safe handling of heavy loads in various facilities. Regular maintenance and inspections are essential to uphold the reliability and safety of RTG crane operations.
Where Can Be Rubber Tyred Gantry Cranes Used?
Rubber tyred gantry cranes are versatile and extensively employed across diverse industrial environments, particularly in container handling operations. Here are the primary locations and applications where rubber tyred gantry cranes are commonly utilized:
Container Terminals: Rubber tyred cranes are widely deployed in container terminals at ports to load, unload, stack, and transport containers between ships, trucks, and storage yards. They play a crucial role in managing container throughput, maximizing yard space, and enhancing the efficiency of cargo handling operations.
Railway Freight Terminals: Rubber tyred gantry cranes are employed in railway freight terminals for the handling of containers and other cargo loaded onto or unloaded from railcars. They facilitate efficient transfer of cargo between rail and road, enhancing the seamless operation of freight logistics.
Distribution Centers: RTG gantry cranes find application in large distribution centers or logistics hubs where they handle containers and oversee inventory management. They contribute to streamlining supply chain operations and ensuring punctual delivery of goods.
Industrial Facilities: Rubber gantry cranes are employed in industrial facilities such as crane for manufacturing plants and crane for precast yard, where heavy materials or equipment need to be lifted and moved. They assist in material handling tasks within the facility, improving productivity and workflow efficiency.
Shipbuilding Yards: RTG cranes are employed in shipbuilding yards to lift and transport ship components, machinery, and other large structures throughout the shipbuilding process. These cranes play a pivotal role in the assembly and construction of ships and vessels.
Construction Sites: In certain construction projects, RTG gantry cranes can be used to lift and transport construction materials, equipment, or prefabricated components. These rubber gantry cranes contribute to construction operations by enabling efficient material handling and site logistics.
Specialized Cargo Handling: RTG straddle cranes can be used for handling specialized cargo, including oversized or heavy items that require precise lifting and positioning. They provide versatility in cargo handling operations across different industries.
