Considerations When Selecting a Rail Mounted Container Gantry Crane
Choosing the right rail mounted crane is crucial for efficient container handling in logistics and ports, rail yards, or intermodal terminals. To ensure optimal performance, several key parameters must be considered when selecting an RMG crane for your operation.
- Load Capacity: The crane’s load capacity must match the weight of the containers, typically 20-foot (TEU) or 40-foot (FEU) containers. Make sure to select a crane that can safely handle the maximum load of your containers, taking into account both the container size and cargo weight.
- Span: The span is the horizontal distance between the crane’s rails and determines how many container rows it can handle. Choose a span that fits your container yard’s layout and allows efficient container stacking.
- Lifting Height: Lifting height is crucial for determining how many containers can be stacked. Higher lifting heights allow for taller stacking but require a crane that can handle the increased height safely and efficiently.
- Container Size (20′ or 40′): Ensure the crane is compatible with the container sizes your operation handles. Most RMG cranes are designed for both TEU and FEU containers, but it’s important to confirm this based on your primary container types.
- Containers Handled Per Hour: Crane efficiency is measured by how many containers it can move per hour. High-throughput operations require cranes with fast lifting speeds and short cycle times to meet demand.
- Spreader Orientation and Rotation: Consider whether the container spreader is parallel or vertical to the crane’s main beam and if it can rotate. Spreader rotation adds flexibility for handling containers in tight spaces, improving alignment and placement.
- Customization and Future Needs: Ensure the crane is tailored to your current needs, with room for future upgrades. Customizing the crane’s capacity, spreader features, and control systems will allow you to scale operations efficiently.

How to Operate and Control a Rail Mounted Gantry Crane?
The automated rail mounted gantry crane is operated by the driver operating the console in the cab. The cab is generally suspended under the trolley and runs with the trolley. All operations of the rail mounted container gantry crane can be realized on the console of the cab. It can also be operated on the side of the RMG railway gantry crane to facilitate the temporary shifting of the crane. When operating on the running side of the crane, it realizes electrical interlocking with the main operating console.
The drive control of rail mounted stacking cranes can adopt different methods according to the needs of users, including conventional AC with eddy current speed regulation brake system; AC stator voltage regulation speed regulation system; thyristor DC constant rate speed regulation system and AC frequency conversion speed regulation system, and different electric drive control systems can be adopted according to different mechanisms.
The Main Structure of Rail-mounted Container Gantry Crane
The structure of a rail-mounted container gantry crane is an intricate assembly of several high-strength components designed to work together for maximum efficiency and durability.By understanding the structure of RMG cranes, you can better appreciate the technology behind these machines and make informed decisions about your purchase and deployment in container handling facilities.
RMG Crane Metal Structure
The metal structure of the rail mounted container gantry crane generally adopts a box structure. It includes:
- Main Beam Structure – The main beam structure consists of two box girders supported on rigid and flexible legs. The connection between the main girder and the rigid leg adopts high-strength bolts or welding, and the connection between the main beam and the flexible leg adopts a hinged connection. For the convenience of installation, the connection between the main beam and the end beam is generally connected by high-strength bolts.
- Gantry Leg Structure – Both rigid and flexible legs adopt box-shaped structure. For rail-mounted container gantry cranes with small and medium spans, the skew force on the legs and main girder caused by the asynchronous operation of the two sides of the crane is borne by the rigid and single-degree-of-freedom hinged connection between the main girder and the rigid and flexible legs. For large-span RMG cranes, the connection between the flexible legs and the main girder adopts a three-degree-of-freedom hinged connection, and a synchronous detection device is provided.
- Trolley Structure – The structure of the running trolley is different depending on whether the hoisting mechanism is a wire rope drum type or a telescopic rigid frame type. Generally, a combined structure of box girder and plate truss is adopted. The driver’s cab, electric control cabinet, festoon cable, etc. are all connected to the trolley structure.
- Auxiliary Structure – Auxiliary structures include electrical room structures, railings, walkways, maintenance platforms, etc.
Lifting And Travelling Mechanisms of RMG
In addition to the special selection of the lifting mechanism of the rail-mounted container gantry crane, the running mechanisms of the trolley and the crane are basically the same as those of other types of overhead cranes and gantry cranes.
- Lifting Mechanism – There are two types of hoisting mechanisms: the wire rope drum type and the the rigid telescopic hoisting mechanism.
- Trolley Running Mechanism – The trolley running mechanism consists of DC or AC motor, gear coupling, block or disc brake, medium-hard tooth surface reducer, low-speed gear coupling, wheels and wheel supports. The arrangement of the driving mechanism is generally divided into two ways: along the direction of the trolley track and perpendicular to the direction of the trolley track.
- Crane Running Mechanism – The structure and form of the RMG crane running mechanism are similar to other types of gantry cranes. Due to the fast running speed of the RMG gantry crane, in order to prevent the wheels from slipping when braking, an electrical control system with good speed regulation performance is generally used, such as thyristor DC voltage regulation, AC frequency conversion speed regulation, AC stator speed regulation, etc.
Electrical and Control Systems
Rail mounted stacking cranes are equipped with sophisticated electrical and control systems that ensure safe and efficient operation. These systems control the movement of the trolley, hoist, and crane itself, as well as manage load handling. Key components of the electrical and control systems include:
- Control Cabin: From where the operator manages crane operations, ensuring precise control of the lifting and moving processes.
- Programmable Logic Controllers (PLC): Automated systems that govern crane functions, optimizing movement patterns and load handling.
- Safety Sensors: Installed throughout the crane to detect potential hazards, such as overloads, misalignments, or obstacles in the crane’s path.
Power Supply System
RMG cranes require a continuous supply of power to operate, which is typically provided through a conductor bar system or cable reel.
- Conductor Bar System: Supplies power via rails positioned along the crane’s track.
- Cable Reel: Supplies power via a retractable cable that moves with the crane.
Other Devices of the RMG Crane
- Buffer System and Bumpers – At the ends of the rail tracks, rail gantry cranes are fitted with buffer systems and bumpers to absorb any excess energy or shock if the crane reaches the end of its track. These components ensure the safety of the crane and its surroundings by preventing collisions or structural damage.
- Slewing Device – For the wire rope drum type hoisting mechanism, the plane slewing mechanism can be composed of wire rope, pulley block, wire rope connection joint and hinge point, rocker arm and support, push rod, etc. For the rigid telescopic lifting mechanism, the spreader can not only rotate in the plane through power, but also float vertically and horizontally (without power) to adapt to the inclination of the upper plane of the container.
- Anti-swaying Device – If it is necessary to install anti-swaying devices for rail mounted stacking cranes, two forms are generally used: when the lifting mechanism is a wire rope drum type, the anti-sway device is pulled by two diagonal thin steel cables, one end is connected to the corner of the spreader, and the other end is wound to the damping drum. When the trolley or crane starts or brakes, the inertia force of the spreader and the container is transmitted to the damping steel wire rope, its swing energy will be absorbed by damping drum; rigid anti-sway device. It is mainly realized by the rigid lifting frame and guiding device.
