Abstract: A hanging cradle arrangement (1) of the kind which comprises a working platform (2), a post or arm (3) which extends upwardly from the platform and which is intended to work with a line (4, 4a, 4b), a first attachment (5) or pulley located above the working platform (2); a guide (6) or pulley located on the free part (3a) of the post (3); normally a second attachment (7) located beneath said guide (6); and device (8) for raising and lowering the working platform by changing the distance between the guide (6) and the first attachment (5) with the aid of a line activating machine (8). According to the invention the arrangement is such that the distance (H) between the platform (2) and the upper free part (3a) of the post can be decreased when the upper free part (6) is in co-action with the first attachment (5), and in that the possibility is provided of further raising the working platform.

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).
