A method for operating a vehicle crane having a lower chassis with boom supports and having an upper chassis with a counterweight in which a live view of the surroundings of the vehicle crane is displayed to the driver. To provide a possibility of operating the vehicle crane that permits safe and simplified manuvering and use, the live view is created at least by way of cameras arranged on the lower chassis, markings indicating the movement ranges of the boom supports and the pivot range of the upper chassis are superimposed to scale on the live view, where the markings are hard-programmed crane-specific overlays and the live view is a crane-specific view that is calibrated with regard to dimensions.

Method for operating a vehicle crane

A telescoping jib of a mobile crane with telescoping sections that telescope inwards and outwards from a jib base casing, and a guying system for the telescoping jib having at least one cable extending between a guying frame and a fixed point by a guying support and is anchored by guying supports, where each guying support comprises a holding mechanism for the cable. A method for guying a telescoping jib of a mobile crane in which at least one cable is anchored between a guying frame on the telescoping jib consisting of a jib base casing and a plurality of telescoping segments and a fixed point on the telescoping jib, and the at least one cable is guided by means of at least one guying support supported on the jib base casing head or a telescoping segment head of the telescoping jib.

Telescoping jib comprising a guying system for a mobile crane and guying method therefor

A telescoping jib of a mobile crane includes sections that telescope out of a jib housing from a transport position into an operating position. A guying system has successively connected tension rods extending from the jib housing to at least one of the extended telescoping jibs by at least one guying support. The mobile crane provides a lighter construction and improved road handling, and an increased load capacity for unchanged telescoping jib measurements. To this end, a guide holder arranged on the jib housing receives the tension rods in the transport position and, in the operating position, at least one movable tension rod on one of the guying supports is respectively securely connected to the outer end of a telescoping section head in an articulated manner and can be secured to a holding mechanism on the opposite end on an adjacent guying support of an adjacent telescoping section head.
