Method of positioning pedestrian bridges

摘要

The method involves handling the bridge using a stretcher with handles at the height of the lower edge corresponding to the height of the users hips. there are two wheels placed under the bridge and forming the tilting pint for rolling. There are two wheels at the front of the bridge situated at a distance allowing stoppage of the central wheels at one side of the trench to allow continuation of sliding movement across the gap with the bridge finally positioned across the gap and the central wheels in the gap. The handles and wheels can be mounted on a stretcher carrier frame formed integrally with the bridge. The stretcher frame can be adjustable for width.
