A lifting vehicle comprises a mobile chassis with a tiltable mast (3) and a lifting device (4,5). Alerting means (15,16) are provided for the purpose of monitoring a load on the lifting device as a result of a cargo being carried thereby. The alerting means comprise a first electronic sensor 11), which records a cargo weight, and a second electronic sensor (12) which records a cargo moment. The alerting means (15,16) are provided with automatic calibration means which, when an output signal below a predetermined threshold value is generated by the one sensor (11), sets to zero an output signal differing therefrom from the other sensor (12).
