An anti-rollover device (50) for a vehicle (10) having at least three wheels (19), in particular for a narrow vehicle and/or for a high-barycentre vehicle such as a forklift, wherein at least two right and left safety legs (5) are provided, each arranged at a respective side (10', 10") of the vehicle, and having a free end portion (59) and an opposite end portion (54', 54") constrained to the vehicle (10), through which the safety legs are connected to the vehicle (10) movably between a rest position (R), of minimum encumbrance with respect to the vehicle, and a support safety position (S) in which the free end portion (59) is located at a safety distance (D) from a respective side of the vehicle (10) in order to stop a lateral rollover of the vehicle thanks to the leg. The device also comprises an actuator means (100) for moving each leg (5) from the rest position (R) to the support safety position (S); a sensor means (110) for measuring a quantity related to an early rollover condition of the vehicle (10), the sensor means configured for producing a measurement signal (110') of such quantity; an automatic control means (120) for receiving the measurement signal and for sending the control signal to the actuator means (100) according to the measurement signal(s) (110'), so that in the case of an early rollover condition at least one of the legs (5, 51', 51") moves from the rest position to the support safety position, resisting the lateral overturning of the vehicle. |
