1. Metal structure: main beam, gantry legs, trolley and auxiliary structure
2. Lifting and traveling mechanism: lifting mechanism, trolley running mechanism, crane traveling mechanism
3. Electrical and control system: control room, PLC, intelligent safety sensor
4. Power supply system: conductive strip system, cable drum
5. Other equipment: buffer system, slewing device, anti-sway device
These structures and equipment work together to provide stable and flexible container handling solutions.
Application areas:
Sevencrane’s rail-mounted gantry cranes (RMG) are widely used in port container terminals, intermodal railway freight yards, container yards and freight stations. RMG cranes are designed for efficient handling and stacking of containers, with high speed, high efficiency and stability, ensuring smooth and efficient operation.
1. Port container terminals: RMG cranes efficiently unload containers from ships and transfer them to storage areas or transportation vehicles, improving port operation efficiency.
2. Intermodal railway freight yards: Simplify the transfer process of containers between trains and trucks, and optimize railway intermodal operations.
3. Container yards: Achieve high-row stacking in limited space, improve storage capacity and efficiency.
Freight stations: Efficiently handle heavy and oversized containers, adapt to different sizes and weights, and quickly complete loading and unloading tasks.
In addition, RMG cranes can also be used to handle containers in special industries such as chemicals, pharmaceuticals, and automobiles, ensuring safe and efficient transportation and storage of special goods. We provide customized solutions based on your needs to improve operation efficiency and ensure safety.
Operation and control of rail-mounted gantry cranes：
Automated rail-mounted gantry cranes are usually operated by the driver in the cab, which moves with the trolley to ensure all-round control. Operation can also be carried out through the control console on the side of the crane, which is convenient for temporary movement and connected to the main control console through an electrical interlocking system.
According to user needs, rail-mounted stacking cranes can be equipped with a variety of drive control systems, including conventional AC eddy current speed regulation, AC stator voltage regulation, thyristor DC constant speed regulation and AC variable frequency speed regulation system to ensure stable and flexible operation.
Key considerations when selecting a rail-mounted container gantry crane：
When selecting an RMG crane for a port, rail yard or intermodal terminal, consider the following key parameters to ensure optimal performance:
1. Load capacity: Select a crane that matches the weight of the container to ensure that it can safely handle the largest loads.
2. Span: Determine the crane span to fit the yard layout to ensure efficient container stacking.
3. Lifting height: Ensure the crane’s lifting height meets stacking requirements to support higher container stacks.
4. Container size: Ensure the crane is compatible with the 20-foot (TEU) or 40-foot (FEU) containers you handle.
5. Efficiency: Select a crane with high hourly handling capacity to meet high throughput needs.
6. Spreader direction and rotation: Consider the spreader’s rotation function to increase flexibility in handling containers in tight spaces.
7. Customization and future needs: Ensure the crane meets current needs and has room for expansion to support future upgrades.
Choosing the right RMG crane will greatly improve your container handling efficiency and operational capabilities.
