Gantry crane (gantry crane) is a kind of crane used for loading and unloading of goods and bulk goods in outdoor freight yard, stock yard. Its metal structure is like a door-shaped frame, which can walk on the ground track, and the main beam can have cantilevers at both ends.

There are many types of gantry cranes, including the following:
It can be divided into single-beam door and double-beam door according to structure
According to cantilever, it can be divided into single cantilever and double cantilever
It can be divided into rail type and tire type according to the support mode
According to the picking device, it can be divided into: hook, grab, electromagnetic and other gantry cranes
The characteristics and lifting performance of different types of gantry cranes are as follows:
Single-beam gantry crane: simple structure, light weight, low equipment and maintenance costs, suitable for small sites and small tonnage operations, such as factories, warehouses, docks, etc., with a lifting capacity of 5-20 tons.
Double-beam gantry crane: with complex structure, large weight, high equipment and maintenance costs, it is suitable for large sites and large-tonnage operations, such as steel, cement, coal and other industries, and the lifting capacity is generally between 20-500 tons.
Rail-type gantry crane: the support mode is rail, which is stable in walking and strong in adaptability, but it needs to lay rail. It is applicable to the loading and unloading of cargo and bulk cargo in the outdoor freight yard, stock yard, such as ports, power stations, railways, etc., and the lifting weight is generally between 5-200 tons.
Tyred gantry crane: supported by tires, it can walk flexibly and is not limited by the site, but its speed is slow. It is applicable to indoor and outdoor operations without fixed track, such as construction site, bridge construction, etc. The lifting weight is generally between 10-50 tons.
Electromagnetic gantry crane: the picking device is an electromagnet, which is suitable for loading and unloading of metal materials. It is applicable to indoor and outdoor operations without fixed track, such as construction site, bridge construction, etc. The lifting weight is generally between 10-50 tons.
The following aspects should be taken into consideration when selecting the appropriate gantry crane:
Structure type of gantry crane: different structure types have different performance and scope of application, which are generally divided according to the form of main beam, leg and sling.
Working environment of gantry crane: different working environments have different requirements, such as indoor or outdoor, temperature, humidity, wind, etc., and corresponding protective measures and configurations need to be selected.
Working parameters of gantry crane: different working parameters have different effects, such as lifting weight, lifting height, span, walking speed, etc., and reasonable specifications and models need to be selected.
Manufacturer of gantry crane: different manufacturers have different quality and reputation, so it is necessary to select a formal and reliable gantry crane manufacturer to understand its production qualification, after-sales service, cost performance, etc.
