Abstract
Supporting apparatus for supporting bridge portions on a portable bridge of the type including a plurality of bridge portions movable from storage positions to positions of use connected to one another in series. The supporting apparatus includes two support legs spaced from one another and swingably supported at respective free ends of a pair of pivotally connected carrier sections. The support legs are further connected with one another by a hydraulic-cylinder arrangement arranged in bypassing relationship to the carrier sections with the holding element designed to absorb relative movement of the support legs resulting from the pivotal connection of the carrier section. Swinging devices are also provided at the free ends of each of the carrier sections for applying forcible swinging movement to the support legs so as to fold same from storage to in-use positions. The pivot axis of the support legs extend at an angle of less than 90.degree. with respect to the longitudinal extent of the support legs.
