Abstract
The safety barrier is for a lift platform that moves between a bottom position and an upper position and safety barrier includes a gate, defining a first plane. The gate includes a surface adapted to engage a cam assembly. The safety barrier has a mount that mounts to the lift platform and a mounting pin, defining an axis, that rotatably mounts the gate. The safety barrier also includes an upright post assembly having an upright post mounted to a non-movable surface, and the cam assembly that applies an upward force to the surface of the gate. When the lift platform moves to the bottom position, the assembly engages the surface and the gate rotates about the axis in the first plane into an open position, and when the lift platform moves to the upper position, the gate rotates about the axis in the first plane into a closed position.
