ABSTRACT:
An exemplary moveable guard rail system of the present invention, useful for preventing fork lift trucks from falling off flat bed trailers, comprises at least two guard rails connected sequentially to each other and to hinged supportive frame members. The guard rails can be moved between extended and retracted positions by hinged arm members which may be powered by hydraulic pistons. Preferably, gimbal bearing members are used for connecting the guard rail or rails to the hinged supportive frame members.
