Abstract

The invention relates to a crane vehicle with an overload safety device with a boom articulated on its uppercarriage, preferably a telescopic boom, which can be rocked by a rocking cylinder articulated on this and the uppercarriage, with extendable sliding beams arranged on the opposite end regions of the longitudinal sides of the undercarriage, the ends of which are provided with extendable support feet, and with a device measuring the angle of rotation of the boom, the signals of which are fed to a processing unit of the overload protection device, in which the overload protection device generates a warning signal and / or stops the crane operation when the crane approaches or exceeds its stability-threatening limits. According to the invention, a monitoring device is provided which detects the extension state or the extension length of the sliding spars, which supplies the overload protection device with signals corresponding to the respective extension length of the individual sliding spars, and that the processing unit of the overload protection device uses the signals of the monitoring device for the extension length of the sliding spars and the signals from the The angle of rotation of the boom-measuring device determines the stability of the standing square resulting from the extension position of the sliding spars for each angle of rotation of the boom.
