gantry craneIt is divided into full gantry crane and half gantry crane. The main girder of the full gantry crane has no overhang, and the trolley operates within the main span; the leg of the half gantry crane has a height difference, which can be determined according to the land construction requirements of the use site.

cantilever gantry craneIt is divided into double cantilever gantry crane and single cantilever gantry crane. Double cantilever gantry crane has the characteristics of reasonable structural force and high utilization rate of site area. Single cantilever gantry crane is often selected due to the limitation of site.

2. According to the main beam form: divided into single main beam gantry crane and double main beam gantry crane

single girder gantry craneThe structure is simple, light in weight and convenient to install. Compared with the double main girder gantry crane, the overall rigidity is weaker. The main girder is generally a partial rail box frame structure. There are two types of door legs: L-shaped and C- shaped. L-shaped has light weight, strong force bearing capacity and convenient installation, but the space at the leg is small. The C- shaped support leg is inclined or curved and has a large lateral space, to facilitate the smooth passage of goods outriggers.

double girder gantry craneIt has the characteristics of large span, strong stability of the whole machine, strong carrying capacity, large weight, high cost, and more models. The main girder can be divided into box girder and truss in two forms, most of which are box girder.

3. According to the form of use: divided into ordinary gantry cranes, hydropower station gantry cranes, shipbuilding gantry cranes, container gantry cranes

Ordinary gantry craneGenerally, it adopts box type and truss type structure, which has a wide range of uses. It is suitable for handling various items and bulk materials, with a lifting weight of less than 100 tons. Among them, the use of ordinary gantry crane grab a higher level of work.

▲ Tieshan lifting semi-portal crane

Gantry crane of hydropower stationMainly used for lifting and opening and closing the gate or installation operations, the span is small, the lifting speed is slow, the weight can reach 80~500 tons.

Shipbuilding gantry craneMainly used for assembling hull. The crane is generally equipped with two lifting trolleys, one with two main hooks, running on the track of the flange above the bridge; The other has a main hook and a secondary hook, running on the track of the flange under the bridge, which is convenient for turning over and hoisting large hull sections.

container gantry craneUsed in container terminals, the height of both sides of the span and the gantry is large, and the working level is high, which can speed up the turnover of container carrying bridges or other cranes.

The above is the tieshan crane summary of the little knowledge, I hope that after reading this article, you can be more clear about their own purchase needs, save costs and time, how quickly and economically to purchase the desired products!
