摘要： 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.

摘要： A safety barrier for a loading dock lift that includes a lift platform that can be raised and lowered. The safety barrier includes a sleeve attached to the lift platform extending along a vertical axis. The sleeve includes guides to define open and closed positions of said gate and said shaft includes a pin that interacts with the guides to produce rotation of said gate between open and closed positions. Consequently each embodiment gate automatically closes due to gravity whenever the lift is raised off the ground and thereby assures that that gates are locked in position when the lift platform has been raised a short distance.
