Gantry cranes, also known as gantry cranes or gantry cranes, commonly known as gantry cranes, are bridge-type cranes in which the horizontal bridges are placed on two legs to form the shape of the gantry. The cranes operate on ground tracks and are used for handling and installation operations in open storage yards, docks, power stations, ports and railway freight stations.best overhead crane supplier

The use of gantry cranes greatly reduces the labor intensity of the loading and unloading workers, improves the working conditions of workers, improves the production capacity of loading and unloading operations and the productivity of labor cattle, and is the key lifting equipment for the quality and efficiency of packaging construction. Gantry cranes are widely used in various industries, such as the ground combination of power field equipment, the fabrication and processing of equipment, the prefabrication of cement frames, and the lifting of objects. Loading and unloading trains and cars in railway freight yards, lifting ship sections in shipyards, lifting gates at hydropower dams, loading and unloading containers at port terminals, lifting and handling bulky items in factories, and carrying out construction work at construction installation sites. Wood yards are stacked on wood and other occasions.

Classification and construction of gantry cranes

Classification and construction of gantry cranes:

According to the application, gantry cranes can be divided into general purpose gantry cranes, container gantry cranes, hydropower station gantry cranes, and dock gantry cranes. In civil engineering construction, the most common one is the general purpose gantry crane. The gantry crane consists of a metal structure (including bridges, legs, cabs, etc.), a mechanism (including a hoisting mechanism together with a small trolley, a lifting trolley traveling mechanism, a gantry crane running mechanism, etc.) and an electrical and control system.

In the form of the pick-up device, the gantry crane can be divided into a hook type gantry crane, a grab type gantry crane, an electromagnetic gantry crane, a dual-purpose or a three-purpose gantry crane.

In the form of legs, it can be divided into L-shaped gantry cranes, C-leg gantry cranes, saddle-shaped gantry cranes with saddles, and U-leg gantry cranes.

According to the form of the traveling mechanism, the gantry crane can be divided into a track type gantry crane and a tire type gantry crane.electric cable hoist supplier

According to the structure of the main beam, it can be divided into box girder gantry crane and truss girder gantry crane; according to the number of main beams, it can be divided into single beam and double girder gantry crane.
