  • Patent number: 5411112
    Abstract: In the field of materials handling, e.g., in warehouses, there is a need for a low-cost shelving access system which does not require a user thereof to carry objects whilst negotiating, e.g., ladders and steps. The disclosure relates to an apparatus including a framework (11); a generally vertical ladder (12a, 12b) secured to the framework; and a goods hoist (20) secured to the framework in such a way that the platform (22a, 22b) of the goods hoist (20) may be maneuvered to a plurality of locations adjacent the ladder (12a, 12b). The ladder (12a, 12b) is moveable laterally on the framework to enable the platform (22a, 22b) of the goods hoist to access any position within the envelope defined by the framework (11).
