A factory crane used in factories is also called overhead crane, bridge crane or EOT crane. An overhead factory crane could be a general factory crane, European factory crane, metallurgical foundry crane, carrier beam overhead crane, explosion-proof overhead crane, electromagnetic overhead crane, power plant overhead crane, steel mill crane, grab crane, etc. A factory crane is a widely used overhead crane in general construction and production factory plants, warehouse, workshops, power plants, metal shop, steel mills, etc. mainly for material handling and lifting. It is the most utilized piece of equipment for lifting big things and transporting them to different spots. It utilizes one or more machines to make mechanical advantages and accordingly move weights past the typical capacity of a human. Cranes are ordinarily utilized in the vehicle business for the unloading and loading of cargo, in the development business for the development of materials and in the assembling business for the collecting of heavy gear.
Overhead Factory Crane | Utilized in So Many Industries
An overhead factory crane may be utilized as a part of industrial facilities and is likewise called overhead bridge crane or EOT crane. An overhead factory crane incorporates European factory crane, carrier beam overhead crane, metallurgical foundry crane, explosion-proof overhead crane, electromagnetic overhead crane, control plant overhead crane, and steel process crane, and so forth. It is broadly utilized, the overhead crane is a part of general development and generation factory facility plants, workshops, warehouse, control plants, metal shop, steel factories, and so on fundamentally for lifting and material handling. The crane should be erected on an unoccupied floor where no industrial nor construction work is to be carried out during erection. The size of the floor must ensure free and convenient handling of the crane during the erection period i.e. setting the crane in erecting position on the floor, turning the suspended crane etc. the most convenient place for erecting the crane is the space between the columns provided there are no horizontal bracings connecting the roof trusses. The roof trusses used for lifting the crane should be checked for stresses during erection with a dynamic factor.
Besides testing the rope & trusses for strength, they should be tested for stability under horizontal forces acting at right angle to the truss plane. The winches employed for lifting the crane should be equipped with ratchet stops. The wire rope employed for erection must have tags indicating wire breaking forces and should be free of defects, fractures, kinks etc. The minimum safer factor should be three. When hoisting the crane or its parts the following conditions should be kept in mind.
- The angle of inclination of the slings should not be less than 45 degrees.
- To prevent rupture of the rope due to sharp edges of lifted materials, wooden or metal lining should be used.
- The number of clamps to be used for fastening the rope should be sufficient.
Also, ensure that the axes of the winch drum should be exactly at the right angle to rope direction.
