Rail Mounted Gantry Crane Specifications

Applications Of Rail Mounted Gantry Crane

RMGs, or rail mounted gantries, are specialized gantry crane systems commonly utilized in intermodal and container terminals, railway freight yards, container yards and ports. Their primary function is to handle large containers with efficiency. These cranes are characterized by a swift running speed and an elevated working level, ensuring smooth and effective operation. Their design contributes to expediting the turnover of container carriers and other cranes in the vicinity. We offer tailored solutions by designing rail gantry crane systems based on your specific application, aiming to enhance work efficiency and prioritize safety in your operations.

Features And Advantages of RMG Container Cranes

• Suitable for various yard conditions – the rail mounted container gantry crane has a relatively large span, and generally can accommodate 8 to 15 rows of containers stacked iwithin the span, and multiple lanes can also be placed in the span, so that the yard space can be better utilized.
• Increased productivity – rail mounted gantry cranes are conducive to the installation of various devices for intelligent control and automated operations, such as storage systems, retrieval systems, accurate spreader positioning systems, anti-sway systems, etc., coupled with the use of high-speed travelling mechanism design, which greatly improves the working efficiency of the intermodal gantry crane.
• Low energy consumption – since the rail mounted quay crane is driven by electric energy, it has certain advantages in terms of energy saving, noise reduction, and waste reduction.
• Stable operation – in order to meet higher requirements for use, the electric drive control system adopts thyristor DC or AC speed regulation drive control system to achieve better speed regulation and control performance. The electrical control system can also adopt conventional AC eddy current speed regulation control or AC stator voltage regulation and speed regulation drive control system.

The Structure of Rail-mounted Container Gantry Crane

RMG Crane Metal Structure

The metal structure of the rail-mounted container gantry crane generally adopts a box structure.

• 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.

Other Devices of the Crane

• 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.

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 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 container gantry 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.
