There are also many classifications of jib cranes, and the structures are of course different. Generally speaking, the main components are cantilever (truss type and box type), balance arm, tower body (or column) and various operating mechanisms. The hoisting mechanism is installed on the trolley or on the balance arm; the cantilever leaning slewing drive mechanism drives the rotation; the mobile trolley completes the movement of the hoisting load along the front and rear directions of the cantilever; some cranes also have walking mechanisms , the crane can move along the track on the ground as a whole.

Common construction tower cranes are cantilevered, and most of them cannot walk. When used for high-rise building hoisting, it is necessary to install an attachment frame with several standard sections on the tower body, which is attached to the building to prevent the tower crane from overturning.
