A rail-mounted container gantry crane consists of double main girders, a rigid leg, a flexible leg, a hoisting trolley, a hoisting winch, a dedicated container spreader, crane bogies, an electrical system, and an operator’s cabin. The gantry structure provides a large clear span between the legs, achieved through a U-shaped open upper section and interconnected leg tops, with a trolley maintenance platform installed above.

Depending on the application site, the crane can be configured without cantilevers or with single or double cantilevers. The hoisting trolley can incorporate both upper trolley rotation and lower spreader rotation. This type of crane is primarily used in railway transfer yards, port terminals, and large container storage yards for loading, unloading, transporting, and stacking containers. It is capable of handling 20-ft, 40-ft, and 45-ft ISO standard containers.
