Overhead cranes are likewise referred to as bridge cranes. They are actually a kind of crane which has a hook and line apparatus which runs along a horizontal beam which runs along two widely separated rails. Various overhead cranes could be seen in a long factory building and they can run along the building's two long walls, similar to a gantry crane.

Normally, overhead cranes include either a double beam or single beam construction. These can be constructed by utilizing either typical steel beams or a more complex girder style. The single bridge box girder crane is complete with the system and the hoist and is operated using a control pendant. Whenever the application requires heavier capacity systems for ten tons or more, double girder bridge cranes are more common.

With the girder box configuration, one major advantage is the lower deadweight with a stronger integrity of the overall system. Another benefit will be the hoist to lift the objects and the bridge that spans the area covered by the crane, along with a trolley to move along the bridge.

The overhead crane is more generally utilized in the steel business. Steel is handled making use of an overhead crane at every stage of the manufacturing process until it leaves a factory as a completed product. The crane is also responsible for pouring raw materials into a furnace and hot steel is then stored for cooling via an overhead crane. As soon as the coils are finished they are loaded onto trains and trucks making use of overhead crane. The stamper or fabricator also depends on overhead cranes in order to handle steel inside the factory.

The automobile business normally uses the overhead crane so as to handle raw materials. There are smaller workstation cranes which are utilized to deal with lighter loads within work areas such as in CNC shops and sawmills.

In basically all paper mills, bridge cranes could be seen being used for regular repairs needing the removal of heavy press rolls and other machines. Some of the cast iron paper drying drums as well as other pieces of specialized machines weigh as much as 70 tons. The bridge cranes are used in the initial construction of the paper machines so as to facilitate installation of these extremely heavy objects.

When constructing a facility utilizing a lot of heavy equipment, the costs of a bridge crane can be largely offset in some circumstances with savings from not renting mobile cranes.

The overhead Rotary crane has one of the bridge ends are attached on a fixed pivot with the other end being carried on an annular track. The bridge can transverse across the circular area underneath. Rotary Overhead cranes provide improvement more than a Jib crane by making it possible to supply a longer reach while eliminating lateral strains on the building walls.

Amongst the very first businesses in the globe to mass produce the very first steam powered crane was Demag Cranes & Components Corp. Following along came Alliance Machine, who is now defunct. Alliance holds an AISE citation for one of the earliest cranes in the United States market. This crane was utilized in service until about the year 1980 and has been retired into a museum in Birmingham, Alabama.

Since the early days, numerous innovations have come and gone, for instance, the Weston load brake is currently considered rare, whereas the wire rope hoist is still popular. Originally, the hoist contained components mated together in what is now known as the built-up style hoist. These super industrial hoists are used for heavy-duty applications such as steel coil handling for example. They are likewise common for users who want better quality and long life from their piece of equipment. These built up hoists even provide for easier upkeep.

Today, several hoists are package hoists. This means they are made as one unit in a single housing which is normally designed for ten years of life. This calculation is based on an industry standard wear and tear when calculating actual life.

In the present North American Material Handling Industry, there are some governing bodies for the industry. The Overhead Alliance is a group which represents CMAA, or also known as Crane Manufacturers Association of America, HMI or likewise known as Hoist Manufacturers Institute and MMA or likewise known as Monorail Manufacturers Association. The members of this particular organization are marketing representatives of the member companies and these product counsels have joined forces to produce marketing materials to be able to raise the awareness of the advantages to overhead lifting.
