Gantry crane is a kind of crane supported by steel frame, which is usually used in industrial environment. It is also called bridge crane and is usually used to handle heavy goods, such as containers, metal structures and machinery. Gantry cranes usually have two rails and an overhead beam, which allows them to easily move large objects horizontally.

Gantry crane usually consists of four basic components: base, crane, gantry and trolley. The base is the foundation of the crane, usually solid or hollow steel box. The top of the base is a crane, which is a device operated by an electric motor for lifting and lowering the load. The gantry is an elevated beam connecting both sides of the crane, allowing the crane to move horizontally. Finally, the trolley is a trolley that can move along the gantry and be used to move the load.
The performance characteristics of the gantry crane depend on several factors, such as the type of motor used, the weight of the load and the size of the crane. The most common type of motor in gantry crane is electric motor, which provides excellent power and efficiency. The weight of the load is an important factor because it affects the lifting capacity and overall performance of the crane. Finally, the size of the crane will affect the lifting capacity, because the larger crane can lift the heavier load more easily.
Gantry cranes can also be used in a variety of applications, from small operations to large industrial projects. Some of the most common uses include moving large containers, lifting heavy machinery and equipment, and loading and unloading goods from ships.
In short, gantry crane is the basic tool for any heavy industrial operation. They are usually composed of four basic components, and their performance characteristics depend on various factors, such as the size of the crane, the weight of the load and the type of motor used. Gantry cranes can also be used for a variety of applications, from small operations to large projects.
