  • Patent number: 6712337
    Abstract: A hoist system comprises at least one mast (2), a hoist trolley (4) moveable externally along the mast, and a platform (24), which is articulately coupled to the hoist trolley (4) so that it is horizontally pivoting about a substantially vertical axis (22) between two end positions relative to the hoist trolley (4). The position of the vertical axis (22) is adjustable for adjusting the distance between the hoist trolley (4) and the platform (24). As a result, the mast can be anchored in a traditional manner at one of the two facade sections of a building extending from a non-right-angled corner, and the platform can be angled horizontally relative to the hoist trolley so that it extends substantially in parallel with the other facade section of the building.

The work platform is releasably connectable to the trolley through interconnection of the first and second pairs of connection members with the work platform in a horizontal position in which the work platform floor is situated at the first level relative the trolley. A transport platform, which has a third pair of connection members, is releasably connectable to the trolley through interconnection of the first and third pairs of connection members with the transport platform in a horizontal position in which its floor is situated at a second level relative the trolley, said second level being below said first level. An adapter enables use of standard transport platform elements.
