Rescue system on high rise buildings for evacuating persons in the case

An amphibious truck includes an arrangement for converting same into a pontoon or ferry vehicle. The converting arrangement comprises two elongated U-shaped support bars arranged on opposite ends of the platform of the truck and transversely to the longitudinal axis of the vehicle and each end of the bar supports for rotation in a plane perpendicular to the platform a triangular guiding member. Stacked on the platform, between the support bars, are two floats which are linked at their ends to the assigned triangular guiding members by hydraulic cylinders. Additional pairs of hydraulic cylinders are linked between a central point of the respective support bars and the free apexes of the triangular guiding members. The resulting hydraulically controlled power transmission link is expandable between the floats and the platform in a plane perpendicular to the bars and makes it possible to tilt the floats into an operative position in alignment with the platform.
