This is the gantry crane order from Uzbekistan in 2021. The customer purchased a set of rail-mounted container gantry crane with a lifting capacity of 41 tons from our crane factory. As a non-standard customized gantry crane order, we placed the order at the factory on June 30th and completed the production on December 1st, which took 5 months. The order was finally sent to Uzbekistan by rail on May 27, 2022. The atlas shows a few pictures of the gantry crane produced in the factory.

What is a rail-mounted container gantry crane

Rail-mounted container gantry cranes are mainly used for container loading, unloading, handling and stacking in container railway transfer yards and large container storage yards.

The rail-mounted container gantry crane is composed of main beam, rigid and flexible door legs, running trolley, lifting mechanism, cart running mechanism, electrical system, operating cab, etc. According to the operation process of the yard, if the cantilever is extended in the direction of a single door leg or in the direction of double door legs, it becomes a single cantilever or double cantilever model, and if it is not extended, it becomes a non-cantilever model. According to the site, container storage and transportation process, and loading and unloading vehicles (container trucks or railway vehicles), different structural forms of no cantilever, single cantilever and double cantilever are used.

Rail-mounted container gantry cranes are divided into different forms according to the structure of the main beam and door legs and the anti-sway device used.

(1) Double-cantilever rail-mounted container gantry cranes need to pass through the inner space of the door legs on both sides because the container needs to pass through. Therefore, the width direction headroom in the door leg is larger. Depending on the form of the main girder carried by the door legs, the double-cantilever rail-mounted container gantry crane generally uses the upper part of the door legs to open into a “U” shape and the upper part of the door legs to form a “Π” shape. The structure of the non-cantilever rail-type container gantry crane is relatively simple because the container does not need to pass through the inner space of the door leg.

(2) Compared with the quayside container crane, the trolley of the rail-mounted container gantry crane runs at a lower speed, and generally does not have an anti-rolling device. If the user puts forward requirements for reducing the operating intensity and improving productivity, an anti-sway device is provided. For rope-type lifting mechanism. The anti-sway is generally realized by applying damping to the rope; for the rigid hoisting mechanism, the anti-sway is realized by rigid components.
