Anti-theft system for manually operated transport vehicles

Described is an anti-theft system for manually operated transport vehicles, especially for shopping trolleys, which have to move on rolling wheels, of which at least one rolling wheel with the rolling behavior of the rolling wheel influencing unit, hereinafter abbreviated unit, equipped from a basic position in which at least one rolling wheel is unaffected, by activating into a position influencing the rolling behavior of the rolling wheel can be transferred and their activation is provided in each case a receiving unit which receives a control signal as soon as the trolley leaves a permitted area defined by a monitoring infrastructure generating the control signal. The invention is characterized in that the unit provides an actuator system which exerts by activating a dosed to the rolling wheel predeterminable braking torque, which prevents the rolling wheel, uninfluenced to rotate about the rolling wheel assignable axis of rotation.
