Abstract
A tensioning system for a mobile telescopic crane having a telescopic mast includes at least one tensioning cable for bracing the telescopic mast and at least one tensioning winch mounted on the crane superstructure for tensioning the cable. The tension in the cable creates a pressure bias within the mast. The winch is movable with respect to said superstructure of the crane and movement of the winch relative to the superstructure also imposes tension on the tensioning cable.
