    Abstract: A device intended for the conveyance of goods utilizing a guide-rail (2) as a goods-conveying track, and a mechanism (4) driven electrically or in some other way and capable of interacting with the goods. The mechanism (4) exhibits two wheels (8,9) capable of interacting with the opposite sides of the guide-rail (2) in relation to which the area of contact (20') of the weight of the goods is located to the side of the wheels (8,9) and the guide-rail (2). The two wheels (8,9) are connected together so as to be driven in synchronism by a driving motor (14). The distance between the driving surfaces of the driving wheels facing the guide-rail is selected so as to match the shape of the driving surfaces in such a way that the space formed between the driving surfaces matches the profile of the guide-rail (2). One of the wheels is divided into two parts (91,92) and has the parts held together by spring pressure (93).
