1ton 2ton 3ton 5ton 10ton 20ton 30ton Customized Single Double Girder Gantry Crane With Electric Hoist

Product Description:

A gantry crane is a variation of a overhead crane, with a core structure of a portal frame consisting of a main beam, legs, hoisting mechanism, and traveling mechanism. It can travel longitudinally along ground tracks, coordinating with the trolley's lateral movement and hook lifting/lowering to operate within a rectangular area.

It features high site utilization, a wide operating range, and strong versatility, capable of lifting long, heavy, and bulk cargo, and adaptable to harsh outdoor environments. Mainly divided into rail-mounted and tire-mounted types, it is widely used in ports, freight yards, shipyards, hydroelectric power stations, and other scenarios, undertaking critical tasks such as container loading and unloading and heavy equipment hoisting, making it an indispensable lifting equipment in modern logistics and heavy industry.

Single girder gantry cranes are a lightweight version of gantry cranes. They consist of a single main girder, two side legs, and a hoisting and traveling mechanism. The structure is simple and compact, lightweight, low-cost, and easy to install and maintain. The hoisting mechanism typically uses an electric hoist, which moves laterally along the main girder track while the crane travels longitudinally along ground tracks, enabling three-dimensional spatial transfer of heavy objects.

The rated lifting capacity of this equipment is typically between 0.5 and 20 tons. It is suitable for small to medium tonnage, low-frequency operations, such as factory workshops, small freight yards, warehouses, and road and bridge construction sites. It mainly undertakes the loading, unloading, and hoisting tasks of light equipment, raw materials, and finished products, effectively improving material turnover efficiency in small spaces and meeting the daily production needs of small and medium-sized enterprises.

Double girder gantry cranes are heavy-duty gantry cranes. Their core structure consists of two parallel main beams, rigid/flexible outriggers, a trolley lifting mechanism, and a trolley traveling mechanism. Compared to single-girder models, they offer greater load-bearing capacity and superior operational stability. The lifting mechanism is mounted on a dedicated trolley, which can move at high speed along the double-girder tracks, ensuring smooth operation and enabling the lifting of large-span, high-tonnage objects.

This equipment has a rated lifting capacity of 10-500 tons, a wide applicable span range, and can adapt to high-frequency, heavy-load operating scenarios. It is widely used in ports, large shipyards, steel mills, and hydropower station construction sites, primarily undertaking key tasks such as container loading and unloading, large ship section lifting, and heavy steel component transfer. It is a core piece of equipment for heavy industrial production and large-scale engineering construction.
