Abstract:
A safety barrier for road use comprises a barrier element (5) which can be displaced between an operative position, above the road surface, and an inoperative position, in which it does not substantially project above the road surface. Preferably provided is a number of sets of aligned barrier elements, rigidly connected to one another, the adjacent sets being connected together by articulated connecting structures (18) which enable one set of barrier elements (5) to be displaced between its inoperative position and its operative position without modifying the positions of the adjacent sets. In this way, one or more stretches of the barrier can be brought into the inoperative condition, leaving the adjacent stretches of barrier in the normal operative condition. The invention is particularly, although not exclusively, suited for the construction of traffic-divider barriers in road tunnels where it is necessary to eliminate the barrier rapidly in the event of an accident occurring.
Abstract:
An industrial vehicle, in particular a trailer or semi-trailer, comprises on its two sides two side-impact guard devices each comprising at least one bar extending in the longitudinal direction of the vehicle and connected to the frame of the vehicle. Set between the bars of the two side-impact guard devices is a housing structure for one or more spare wheels, in such a way that said housing structure and the spare wheel or wheels housed therein contribute, together with the aforesaid bars, to absorbing the energy of a lateral impact.
