Rail mounted container gantry crane, also known as container gantry crane, is a gantry crane dedicated to container terminals, railway transfer yards and storage yards, which is used for container loading, unloading, handling and stacking. Its metal structure is like a door-shaped frame, with two support legs installed under the main beam, which can directly walk on the ground track. The main beam can have cantilever beams at both ends.

The rail type container gantry crane consists of a main beam, rigid and flexible door legs, a running trolley, a lifting mechanism, a crane running mechanism, an electrical system, and an operating cab.

This model is also equipped with telescopic container spreaders for lifting containers of different specifications. The opening and locking action and extension of the lifting appliance are operated by the driver in the control room. At the same time, in order to adapt to different container stacking directions and container trailer walking directions, container cranes can be designed with a rotating mechanism, which can make the container rotate freely to improve loading and unloading efficiency.

The drive control of rail mounted container gantry crane can adopt different ways according to the needs of users. At present, the commonly used ones include: (1) conventional AC speed regulating braking system with eddy current; (2) AC stator voltage regulation and speed regulation system; (3) Thyristor DC constant rate speed regulation system and AC variable frequency speed regulation system, and different electrical drive control systems can be adopted according to different mechanisms.

The rail mounted container gantry crane is operated by the driver on the linkage console in the cab. The driver's cab is generally suspended below the car and moves with the car.

The lifting capacity of rail mounted container cranes corresponds to approximately 20 tons, 25 tons, and 30 tons for 20 foot, 30 foot, and 40 foot long containers, respectively. The span is determined by the number of container rows that need to be crossed, with a maximum of about 60 meters. According to the requirements of the container yard, the lifting height of the rail mounted container gantry crane shall be determined by stacking three to four or stacking four to five.

In container distribution areas such as ports and docks, the application of rail mounted container gantry crane has been very common. Mainly because it has the following advantages:

1. The span of the rail mounted container gantry crane is relatively large, which can generally accommodate 8 to 15 columns of containers to be stacked in the middle of the span, or multiple lanes can be placed in the middle of the span, so that the site space can be better used.

2. Generally speaking, rail mounted container gantry crane is equipped with various devices that are convenient for intelligent control and automatic operation, such as storage system, retrieval system, positioning system, etc. In addition, the mechanism design with high running speed is adopted, which greatly improves the working efficiency of the equipment.

3. As the rail mounted container gantry crane is driven by electric energy, it has certain advantages in reducing noise and eliminating exhaust emissions, and is a more environmentally friendly equipment.
