<p>The device has a helicoid track (2), and a carrying vehicle (1) that is provided with a bearing unit (3) on its periphery. The bearing unit is adapted to roll on the helicoid track. An electrical motor is adapted to drive and/or to slow down the bearing unit. An annular frame is arranged for carrying the bearing unit, and another frame is arranged for carrying a hoist. The latter frame is concentric to the former frame. Rotation of the latter frame with regard to the former frame is contrary to a direction of rotation of the former frame induced by the bearing unit. An independent claim is also included for an underground waste storage installation.</p> |
