Abstract
A mobile crane has at least two crane booms which are connected together by a joint such that the angular position with respect to each other can be adjusted. At least one hose between the crane booms, and the hose is exposed in the region of the joint in at least one angular position of the crane booms. At least one flexurally elastic sheet is connected with the at least one hose or covers it at least in the exposed region and can flex when the angular position of the at least two crane booms is changed. The at least one flexurally elastic sheet can be moved into or respectively out of one of the crane booms upon a change in the angular position of the crane booms.
