Advantages Of Rail Mounted Container Gantry Crane For Sale

Rail mounted gantry crane, also known as RMG crane, is a great choice for handling and stacking large containers. It runs along the track, lifting and stacking containers within the specified range of the container yard. The lifting mechanism, trolley mechanism and crane travelling mechanism are mostly controlled by AC frequency conversion. The hoisting mechanism is generally in the form of a single drum, and it can also be designed in the form of a double drum as required.

• Electric drive, save energy and reduce pollution – since the rail mounted container gantry port crane is driven by electric energy, it has certain advantages in reducing noise and eliminating exhaust emissions, and is a more environmentally friendly device.
• High yard utilization – the span of the RMG container crane is relatively large. Generally, it can accommodate 8 to 15 columns of containers stacked inside the span, or multiple lanes can be placed in the span, so that the site space can be better utilized.
• High degree of automation – generally, various devices for intelligent control and automatic operation are installed on the rail-mounted container gantry crane, such as storage system, retrieval system, positioning system, etc. In addition, the mechanism design with high running speed is adopted, which can greatly improve the working efficiency.
• Reliable performance – the rail mounted gantry crane is superior to the rubber tyred gantry crane in terms of stacking height, stacking container positioning accuracy control, anti-sway performance and the stress state of the steel structure.

How to Operate A RMG Container Gantry Crane?

The rail-mounted container gantry crane is operated by a driver sitting in the driver’s cabin and controlling the linkage platform. The driver’s cabin is generally suspended under the trolley and moves with the trolley.

All container gantry crane operations can be performed on the linkage platform in the driver’s cabin. The driver can also operate the crane on the running side of the crane to facilitate temporary moving of the crane. When operating on the running side of the crane, electrical interlocking is achieved with the main operating linkage platform.

The drive control of the gantry container crane can be customized according to the user’s needs and currently includes: (1) conventional AC with eddy current speed regulation and braking system; (2) AC stator voltage regulation and speed regulation system; (3) thyristor DC constant speed regulation system and AC variable frequency speed regulation system. Different electrical drive control systems can be used for different mechanisms.

The Main Container Gantry Crane Structure

Metal Structure

• Main Beam – the off-track box girder is often used. In order to avoid the high stress area caused by the wheel pressure for the flange weld, the “T” steel is used to weld the main beam face plate and load-bearing web to the rail part. The connection between the main beam and the rigid leg adopts high-strength bolts or welding, and the connection with the flexible leg adopts a hinged connection.
• Legs – both the rigid leg and the flexible leg adopt a box-shaped structure. For rail-mounted gantry container cranes with small and medium spans, the legs on both sides are made of rigid legs. For “Π” shaped legs, the strength and stiffness along the direction of the intermodal gantry crane are realized through the rigid connection between the legs and the top beam. For U-shaped legs, it is realized through the rigid connection between the legs and the bottom beam, while the strength and rigidity along the direction of the trolley is realized by the rigid connection of the main beam and the rigid leg.
• Trolley – the structure of the 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, anti-swaying device, festoon cable, etc. are all connected to the trolley structure.
• Auxiliary structure – the structure includes the electrical room and escalators, walkways, maintenance platforms, etc., located on one side of the main beam.

Lifting mechanism

• The lifting mechanism consists of electric motor, disc brake, reducer, and duplex drum. The wire rope drum lifting mechanism is driven by an AC motor, and a single-layer rope groove drum is driven by a closed spiral gear reduction box to wind the rope. The motor has enough power to ensure good acceleration performance.
• An elastic coupling with a brake disc is provided between the hoisting motor and the reduction box. The brake is a hydraulic push rod disc brake released by a spring brake push rod.
• An overspeed switch is provided on the high-speed shaft end of the hoisting mechanism. When the motor speed exceeds 115% of the rated speed, the entire machine is stopped in emergency.
• Detected by the weight sensor, when the load under the spreader is between 100% and 110% of the rated load, the rated load indicator light in the driver’s cab is displayed. When the load under the spreader exceeds 110% of the rated load, the buzzer alarms, the overload indicator flashes, and the PLC prohibits the lifting mechanism from continuing to lift upwards, but allows the lifting speed limit to drop and lower the load.

Trolley travelling mechanism

• The trolley running mechanism generally consists of a wheel set, a motor, a reducer, a brake, a coupling, etc. or a three-in-one reducer and a guide wheel set.

Crane travelling mechanism

• RMG crane travelling mechanism mainly consists of three-in-one reducer drive, rail clamp, buffer, wheel clamp, etc.

How Does A Container Gantry Crane Work?

Container gantry cranes consist of several essential components and operate with precision and safety in mind. Here’s how they work:

• Lifting Mechanism: The heart of the crane is its lifting mechanism, typically comprising a spreader, ropes, and winches. The spreader attaches to the container, while the winches use powerful motors to lift and lower it with precision.
• Movement: The crane’s bridge and legs move along a set of rails, positioning it precisely above containers. This lateral movement ensures containers are picked up or placed down with pinpoint accuracy.
• Control: Skilled operators control the crane’s every movement, utilizing advanced control systems to ensure safe and efficient container handling.
