A vehicle crane having a telescoping jib, comprising a basic box with retractable and extendible inner boxes and a securing and locking unit that comprises a first adjusting cylinder and a second adjusting cylinder which are each designed as unilaterally acting hydraulic cylinders with a first spring element and a second spring element as well as a first line and a second line, where the first adjusting cylinder moves locking bolts between operating states of unbolted and bolted and the second adjusting cylinder moves driving bolts between operating states of secured and released. In the event of a malfunction, the first adjusting cylinder moves to the bolted operating state and the second adjusting cylinder moves to the released operating state.

A telescoping jib system of a mobile crane having a basic telescoping jib and an additional telescoping jib that can be retracted and extended via a telescoping cylinder with a securing and locking unit. In order to improve the telescoping jib system, it is proposed that a securing unit is arranged on a tip of the telescoping cylinder, the securing unit comprises exclusively at least one driving bolt, via which an additional telescoping jib separate from the basic telescoping jib can be retracted into the basic telescoping jib. The invention also relates to a method for lengthening a basic telescoping jib of a mobile crane by means of an additional telescoping jib to form a telescoping jib system.

An outrigger assembly for support of a mobile crane or excavator upon the ground, includes a plurality of outriggers mounted to a vehicle frame and having free ends, wherein each of the outriggers has a ground-engaging pad connected to the free ends for vertical movement in relation to the ground. Each of the outriggers has at least one outrigger arm unit movable with respect to the vehicle frame between an idle position suitable for travel between sites, and an operative position suitable for support on the ground, wherein the outrigger arm unit includes an outrigger arm made of a hollow profile which has a lower part of U-shaped configuration and an upper part of calotte-shaped configuration.
