Gantry Cranes Categoy And Lifting Performance
Gantry crane (portal crane) is a kind of crane used for loading and unloading of outdoor freight yard, material yard and bulk cargo, whose metal structure is like a portal frame, which can be walked on a track on the ground, and the main beam can have cantilevers at both ends.
Gantry Crane Categories
1. According to the structure, gantry cranes can be divided into single beam cranes and double beam cranes.
2. According to the cantilever, gantry cranes can be divided into single cantilever gantry cranes and double cantilever gantry cranes
3. According to the picking device, gantry cranes can be divided into: hook, grab, electromagnetic gantry cranes.
Gantry Crane Characteristics and Lifting Performance
Single Beam Gantry Crane: Simple structure, light weight and low equipment maintenance costs, suitable for small sites and small tonnage operations, such as factories,
Double Girder Gantry Crane：Complex structure, large weight, high equipment maintenance costs, suitable for large sites and large tonnage operations, such as steel, cement, coal and other industries, lifting weight is generally between 20-500 tons.
Track Gantry Crane：The support mode is the track, the walking is stable and the adaptability is strong, but the track needs to be laid. It is suitable for the loading and unloading of outdoor freight yard, material yard and bulk cargo, such as ports, power stations, railways, etc., the lifting weight is generally between 5-200 tons.
Electromagnetic Gantry Crane: The picking device is an electromagnet, which is suitable for loading and unloading of adsorbed metal materials. It is suitable for indoor and outdoor operations that do not require fixed tracks, such as construction sites, bridge construction, etc., and the lifting weight is generally between 10-50 tons.
