ABSTRACT:
This invention concerns a self-supporting and self-contained elevator suitable for the transfer of loads from one level to another of a building structure. The elevator is capable of being preassembled and placed into an existing well or space provided in a structure. The invention utilizes rigid guide devices for control of both the speed and direction of movement of the elevator. In the instance of failure of such guide devices, further movement of the elevator is precluded. The arrangement of the invention functions without reliance on conventional hoisting devices in the form of cables or ropes, effectively precluding the need for incorporation of sophisticated safety devices to operate to stop the elevator in the instance of failure of the hoisting device.
