Description

Gantry cranes are generally classified according to the structure of the mast, the form of the main beam, and the form of the spreader.
Divided by door frame structure:
(A) Full gantry crane: The main beam has no overhang(cantilever), and the trolley is carried in the main span.
(B) Semi-gantry crane: the outriggers have a height difference, which can be determined according to the civil requirements of the site.
(C) Double cantilever gantry crane: the most common type of structure, the structural force and the effective use of the site area are reasonable.
(D) Single cantilever gantry crane: This type of structure is often selected due to site constraints.
Divided by main beam structure:
(A) Single girder gantry crane
Single beam cantilever gantry crane has a simple structure, convenient manufacturing and installation, and low mass. The main beam is mostly a deviating box frame structure. Compared with the double girder gantry crane, the overall stiffness is weaker. Therefore, this form can be used when the lifting weight Q≤50t and the span S≤35m. There are two types of L-shaped and C-shaped door legs of the single main portal beam crane. , Its own mass is small, but the space for lifting the goods through the legs is relatively small. The C-type feet are made inclined or curved, with the purpose of having a large lateral space to allow the goods to pass the feet smoothly.
(b) Double girder gantry crane
Double-girder gantry crane has strong bearing capacity, large span, good overall stability, and many varieties, but its own quality is larger than that of single-girder gantry crane with the same lifting capacity, and the cost is higher. According to the structure, it can be divided into box type beam and truss type beam, depends on the project or work site.
