Foldable bridge platform

Abstract

A foldable bridge platform including a platform, a base bracket with casters installed beneath the bottom thereof, and a vertical rail erected and secured on the base bracket which provides the platform with a guide for adjusting the height thereof. The platform includes at least one main board and two side boards which are pivotally connected to the outer sides of the main board. The main board has a plurality of supporting bulges fixed at the outer sides thereof in order to support the horizontally unfolded side boards. By folding up the side boards of the platform, the width of the bridge platform can be greatly reduced. The foldable bridge platform is thereby convenient for movement and storage.
