Abstract

The vehicle used for transferring of loads has an overhanging telescopic arm whose free end carries load handling equipment. This vehicle is provided with means for generating audible or visible alarm signals for indicating to the driver an overloaded or unstable state of the vehicle. The warning signal is generated when the vehicle is about to become unstable. The loading measuring device is preferably arranged in the vicinity of the axle which could be lifted clear from the ground when the vehicle becomes unstable. A sensor is provided for sensing the turning moment exerted by the overhanging arm (13) relative to other parts of the vehicle. An alarm system is actuated by the sensing arrangement for generating a signal. The sensing system has a loading measuring device in the rear axle of the vehicle.
