Abstract:
An automotive vehicle crane, comprisinga framework provided in a longitudinal axis of the vehicle, said framework having a leading end and a rear end,a crane superstructure rotatable connected to said framework by a slew ring supported on the framework,a telescoping crane boom connected to said crane superstructure,a plurality of extendable outrigger cylinders,and a cab,wherein outrigger cylinders are connected to said vehicle framework along said longitudinal axis of the vehicle, a first outrigger cylinder connected to the leading framework end and a second outrigger cylinder connected to the rear framework end, said first and said second outrigger cylinders being mounted on the vehicle framework in a horizontally extendable manner, andwherein a third and a fourth outrigger cylinder are connected to said framework proximate to said slew ring by a first and a second lateral outrigger beam, said lateral outrigger beams being extendable relative to said framework so as to move said third and fourth outrigger cylinders in a direction transverse to the longitudinal axis of the framework,wherein said cab can be pivoted relative to the crane superstructure and slew ring from a position provided for driving operation to a position appropriate for crane operation,wherein during driving operation the crane boom can be laid down pointing to the rear such that during driving operation, the cab is associated to the leading framework end while an end of the crane boom is associated to the rear framework end, andwherein the lateral outrigger beams are laterally extendable from a first and a second accommodation case such that said third and fourth outriggers and said slew ring lie in a straight line, said accommodation cases being arranged in parallel to one another, and said first and second cases being mounted on opposite sides of the slew ring on said framework.
