Single girder gantry crane
The single girder gantry crane has a simple structure, is simple to build and install, and has a low self-mass. The main beam is primarily a box-shaped structure that is off-track. The overall stiffness is lower when compared to double-girder gantry cranes. As a result, this form can be used when the weight is Q50t and the span is S35m. L-shaped and C-shaped door legs are used on single-gantry gantry cranes. The L-shape is simple to fabricate and install, and the stress conditions are favorable. The L-shape has a low quality. However, the space available for lifting cargo through the legs is limited.The C-shaped legs are inclined or curved to allow for a large lateral space for the cargo to pass through.
Double girder gantry crane
Double girder gantry cranes have a high lifting capacity, a large span, overall stability, and a wide range of options, but their quality is higher and their cost is higher than single-girder gantry cranes of the same weight. It is classified into two types based on the main beam structure: box beam and truss. At the moment, the structure is generally more box-shaped. Finally, gantry cranes are classified into two types based on girder design: truss gantry cranes and box girder gantry cranes.
Truss type gantry crane
Truss gantry crane - The structure of truss gantry cranes are made of angle steel or I-beam structural forms which have the advantages of low cost, light weight, and strong wind resistance. Huge deflection, low rigidity, relatively low reliability, and frequent detection of welding spots are the shortcomings of truss beams due to the large number of welding points and faults in the trusses themselves. Low lifting weight and low safety standards make it ideal for sites where lower safety needs.
Box gantry crane
Box girder gantry crane - Steel plates are welded together to form a box construction with great safety, rigidity, and other properties. It's usually reserved for gantry cranes that have a lot of tonnage or enormous tonnage whereas has the disavantages of high cost, heavy weight, and low wind resistance.
Adjustable gantry crane
Adjustable gantry crane - Adjustable gantry cranes are used in warehouse applications where items must be moved through aisles, entrances, around impediments, and over or under obstacles. In welding facilities, fabrication industries, and other places, an adjustable gantry crane is frequently used to raise pieces and equipment which has high flexibility in adjusting lifting height and width.
Portable gantry crane
Portable gantry crane-Portable gantry cranes are versatile, with the ability to be replaced and relocated, as well as the ability to travel quickly and easily from one job site to another.
Rail Mounted gantry crane
Rail mounted gantry crane -A rail-mounted gantry crane is used to move big loads through a defined route, either manually or mechanically.
