Retro-reflectors incorporating measures to prevent lifting movements and to compensate for lifting scaffolding deformations

摘要

The present invention concerns a narrow-gauge headlamp comprising: a vehicle body (12) with a longitudinal direction and width device, wheels associated with the vehicle body (12) (14a, 14b, 18);a propulsion system designed to accelerate at least one of the wheels (14a, 14b, 18); a lifting device (20);where the lifting equipment (20) is mobile in relation to the vehicle body by means of a bearing device (12); at least one recording unit (22, 24a, 24b),which is designed to capture at least one condition parameter of the narrowband and/or its surroundings and to provide relevant data; at least one actor designed to achieve a movement of the lifting frame (20) in relation to the body of the vehicle (12) corresponding to at least one degree of freedom; and a control unit, which is operationally linked to and equipped with at least one recording unit (22, 24a, 24b) and at least one actor: determine the actual state of the narrowband on the basis of at least one recording unit (22, 24a, 24b) recorded by at least one recording unit (22, 24a, 24b);to determine the effect of the action of at least one actor on the actual state; and to control at least one actor in such a way that a difference between the specified actual state and a predetermined target state is reduced.
