AbstractThe invention is a device, such as a chute or a conveyor belt, for receiving and transferring work pieces in a factory, mounted on a set of legs with lockable wheels at the bottom of each leg. Each leg is equipped with an hydraulic extension unit that is operated by air pressure. The air pressure is provided, for instance, from a machine, such as a press, that performs work on the work piece. Each leg is individually adjustable by the pneumatic extension unit, allowing the device atop the legs to be adjusted in height from the support surface, and maintained level or tilted from side to side or front to back. The wheels on the leg bottoms allow the device supported on the legs to easily move from one location to another on the factory floor. The legs may optionally be designed to fold up against the bottom of the supported device for ease of storage of the device.The advantages of the height and level adjustable features of the work surface device include allowing workers of various stature to safely and comfortably handle work pieces. A single device can be height and level adjusted for each worker that uses the device.
