Abstract
A balanced vertical moving apparatus for moving a body having a first weight toward, or from, a selected elevation includes a loading device, on which the body is designed to be loaded; a moving system powered by a power source; a first detection unit detecting the first weight, which is interposed between the loading device and the moving system; a storage system storing a reference weight in a storage device; and a drive system driving the moving system, which is connected to the first detection unit and the storage system and is designed to actuate the moving system, the drive system having at least two alternately selectable operating states, a first lifted state and a second lowered state, which are both designed to be selected by an external control system, a third automatic actuation state being selectable when an additional external force is applied to the loading device.
