An overhead bridge crane, also known as a bridge crane or an overhead travelling crane, is a type of crane that is commonly used in industrial and manufacturing settings. It consists of a horizontal beam or girder that is supported by two or more vertical columns or pillars, and a trolley that runs along the length of the beam. The trolley can be fitted with a hoist, which is used to lift and move heavy objects within the working area of the crane. Overhead bridge cranes are designed to handle heavy loads that are beyond the capacity of human workers, and they are typically used for tasks such as loading and unloading heavy equipment, moving raw materials, and assembling large structures. They are an essential piece of equipment for many industrial operations and are used in a wide range of industries, including construction, mining, and manufacturing. Overhead bridge cranes are available in a variety of configurations, including single girder and double girder models, and they can be powered by electricity or air pressure. They are designed to be safe and efficient, and they come equipped with features such as overload protection, emergency stop controls, and safety interlocks to prevent accidents and injuries.
