Hoist device for use in tunnel or well in underground waste storage installation, has helicoid track, and bearing unit that is adapted to roll on helicoid track, and motor unit that is adapted to drive and/or to slow down bearing unit

摘要

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.
