The lift cage (10) has a flat floor (16), and there is a door (20,22) at each end. The side walls may be a lightweight fabric or mesh construction (36). The floor is hung from a crossbeam (24) by a cable stayed arrangement with cables (38) attached at their ends to the floor and passing over the beam. The attachments are more closely spaced at the ends of the floor (40,42) than at the central portion (44). |
