ABSTRACT:
The present invention entails a stationary lift structure for supporting and handling goods and articles and which is particularly designed for use in pharmaceutical or medical-type applications because of the utilization of a sterile-type enclosure for the various components that comprise the stationary lift structure. Structurally, the lift device includes a mainframe that is adapted to rest on a support surface. The mainframe includes a pair of upstanding guide rails. Movably mounted on the guide rails is a carriage that carries a bed structure that can be moved between a lower position just above the support surface and an elevated position. A pneumatically driven hydraulic fluid control system is employed to drive the carriage and load the bed structure from its lower position to an upper elevated position. A tie or carrier bar is adapted to interconnect the mainframe structure with the bed structure such that the entire lift support structure can be picked up and moved by simply engaging and lifting the bed structure of the device.
