Gantry Crane is a variant of bridge cranes, mainly being used for loading and unloading operation of the outdoor goods yard, stock ground and bulk cargo. Its metal structure is like a portal framework. Two stabilizer blades are installed under the load girder and it can walk on the tract of the ground directly. Two ends of the girder can have outriggers on them. We design, manufacture, install and maintain an extensive range of ganty cranes, we can also provide a tailor-made solution for your processes.
There are various gantry crane types classified by purpose.
|Gantry crane types||Lifting capacity||Span|
|General gantry crane||<100 ton||4-39m|
|Hydropower station gantry crane||80-500 ton||8-16m|
|Shipbuilding gantry crane||100-1500 ton||Up to185m|
|Container gantry crane||20, 25, 30 ton||Up to 60m|
Gantry crane girder design. According to the main beam structure, gantry cranes are divided into single girder gantry crane, double girder gantry crane, truss girder gantry crane, and box girder gantry crane, etc.
Indoor or Outdoor Use. The working environment of the crane affects the choice of crane materials and its electrical components. Considering extreme temperatures, weather exposure and harsh working environments will help us choose suitable materials and processing techniques.
Speed. Gantry cranes are widely used, but their loads usually move at a slower speed. If you need higher operating speeds, you may want to consider using other types of cranes.
Span. The span of the gantry crane is an important factor affecting the crane design. When you choose, the span should be reduced as much as possible on the premise that the equipment usage conditions and the span standard are met.
In the machiner and equipment industry, there are corresponding standards for the production and inspection of general gantry crane.These standards cover design, manufacturing, material selection, and even painting. The design of gantry cranes must follow the specifications and regulations such as gantry crane construction guidelines and safe operation guidelines. All gantry cranes manufactured or sold by Zhonggong comply with the requirements set by these organizations.
Gantry cranes are lightweight and portable and use legs to support the bridge, trolley, and hoist. They can travel on single or double rails on the ground. The maximum load capacity of these cranes can reach up to 100 t, the maximum span up to 40 m, and the lifting height up to 15 m. The crane can operate in indoor and outdoor environments from -20°C to +40°C.
