Overhead cranes, also known as bridge cranes, are usually used for hoisting materials in workshops, warehouses, and stockyards. It runs through the tracks on both sides of the viaduct, lifts materials without obstacles, and makes full use of the space under the bridge. Overhead cranes are currently the most widely used heavy lifting equipment. It is important crane equipment for realizing modern industrial production and transportation mechanization and automation.
Single girder overhead crane is widely used for lifting goods in factories, warehouses, and material plants. It has a reasonable structure and high overall steel strength. The overhead crane is usually used in conjunction with CD and MD electric hoists. This kind of crane equipment is not allowed to be used in flammable, explosive and corrosive environments.
Double girder overhead cranes are usually used in open warehouses, railways and other places to carry out common loading, unloading and material handling tasks. It is a heavy-duty bridge crane that is frequently used.
Electromagnetic overhead crane is developed from the double-girder bridge crane. The crane body has a detachable electromagnetic chuck and a configured operating system to control the transportation and lifting of metal objects by the electromagnetic chuck. It is suitable for loading and unloading or transporting metal products, such as steel ingots, structural steel, iron, scrap iron and scrap steel.
The lifting capacity of grab bridge crane is about 5-25 tons. It is widely used in power stations, warehouses, workshops, and ports for loading and unloading scattered objects. Grab bridge cranes are mainly used for medium to heavy lifting work.
Foundry overhead crane is mainly composed of bridge, hoist, hook, trolley mechanism and electric part. The main hook employs the constant-spacing connecting traverse as the load handling device to hoist steel ladle and the auxiliary hook acts in concert with the main hook to accomplish pouring of molten steel slag, and other auxiliary hoisting.
Explosion proof overhead crane is evolved on the basis of the LDA model, which features reasonable structure, beautiful appearance, and good explosion-proof performance. It is usually used with HB type and HBS type explosion-proof electric hoist, and it is a light crane.
Material handling bridge cranes are a new generation of cranes with intelligent features. Compared with previous cranes, its lifting speed is doubled. Using stepless variable frequency motor design, stable crane travel is ensured. In addition, the overhead crane features compact structure, saving a lot of space.
Rail mounted overhead crane is a kind of light crane, which is usually used together with electric hoist. It’s widely applied in steel plants, cement plants, power plants, mining industry, food industry, chemical industry, shipyards, stone yards and warehouses and other places.
European standard overhead crane is designed according to international standards: FEM (Europe), DIN (Germany), ISO (International). It has many advantages such as strong rigidity, light weight, low power, and outstanding structural design.
