Gantry cranes are mainly used for loading and unloading goods and lifting large components in ports, freight yards, construction sites, and other open places. This article will give you an in-depth understanding of the gantry overhead crane's definition, structural composition, design points, functional features, and the difference with the Overhead Crane. If you don't know how to choose the right Gantry Crane or want to know its price range and application areas, this article will be your ideal guide.
Gantry cranes have a gantry frame structure, consisting of a main beam spanning horizontally, outriggers supported vertically on both sides, and other structures such as a lifting mechanism. Its outriggers and main girder form a solid portal frame structure, so it is called a gantry overhead crane. Longitudinal movement is realized through the rail travelling mechanism, and is equipped with auxiliary facilities such as a driver's room and a windproof device etc. The overall design is of large span and strong rigidity, which is suitable for heavy lifting and loading/unloading operations in ports, stockyards, and other open-air places.
Gantry cranes are mainly used in large-scale material handling, hydropower engineering, railroad manufacturing, and other projects, with a variety of functions, which can effectively complete the loading and unloading of heavy goods, handling, and stacking.
A Gantry crane is composed of a main beam, outriggers, trolley running mechanism, lifting mechanism, cab, ladder and platform, buffer, and other components. The functional characteristics of each part are as follows:
Weihua, as a professional gantry overhead crane manufacturer and customizer, has multiple different types of gantry mounted cranes. If you still don't know which type of gantry crane can enhance the productivity of your factory. The following article will bring you a comprehensive understanding of the different types of gantry cranes and their application scenarios.
Small portable gantry crane: A Small portable gantry crane is an economical and flexible light lifting equipment. Equipped with universal wheels with braking function, it can move flexibly on different floors and easily adapt to a variety of operating environments.
Grúa semipórtico BMG: The BMG semi gantry crane consists of two main beams, an electric trolley, and a supporting leg on one side. Adopting this structure of a gantry crane can fully utilize the site space.
Grúa de pórtico de una viga MH: The Grúa de pórtico de una viga MH is a small gantry crane with an electric hoist as the lifting system and with rail travelling. This type of gantry crane is popular for its compact structure, easy operation, and small footprint.
Truss Gantry Crane: The truss gantry crane is a light lifting equipment for a specific working environment. The gantry-style column design not only gives the entire structure a unique appearance but also enhances stability by reducing wind resistance.
Grúa pórtico europea de dos vigas: The European double beam goliath crane adopts the advanced European FEM standard design and manufacturing. Compared with the ordinary MG type, its main features are the use of European standards, a hardened surface of the reducer, a three-in-one drive, and PLC+frequency conversion control technology.
RTG Rubber Tyred Gantry Crane: The Rubber Tyred Gantry overhead Crane (RTG for short) is a kind of special lifting equipment dedicated to stacking operations in container yards. RTG integrates automation technology, such as an automatic positioning system and an anti-sway control system, which effectively improves the safety and efficiency of operation.
Rail Mounted Gantry Crane: The rail mounted gantry crane is applicable to remove, load, and unload international standard containers. It is a highly efficient loading and unloading equipment, mainly for in ports, docks, and inland container yards. The main function is stacking, handling, and transshipment of containers from ships to land transport.

The power source of a gantry overhead crane is a multi-system collaborative system driven by electricity or hydraulics. It usually uses an industrial power grid or a diesel generator as the main power source, transfers energy to various components through electric motors or hydraulic pump stations, and is assisted by frequency converters, reducers, and transmission components to achieve precise control and power transmission. Each type of power supply for a gantry crane has its features and advantages. If you have any need for a gantry crane sliding line, conductor line busbar, or cable reel, please feel free to contact us.
Goliath Crane consist of an A-type or rigid outrigger-supported beam structure and typically run on ground tracks or wheels. The overall design has a large span and strong rigidity, and is suitable for lifting and loading, and unloading operations in open-air places such as port container stacking, large construction sites, and material yards. In contrast, an overhead crane bridge along the track laid on both sides of the elevated longitudinal run, you can make full use of the space under the bridge for lifting materials, for material handling in limited spaces.
