Simple beam bridge type crane

It is also called beam crane, and its structure is similar to that of common bridge crane. The weight, span and working speed are smaller. The main girder of the bridge is a simple section beam made up of I-beam or other steel and plate steel. The trolley is made of a hand hoist or an electric hoist with a simple trolley, and the trolley runs on the lower flange of the i-beam. The bridge can run along the elevated track or along the track below the viaduct. This crane is called the suspended beam crane.
