    Patent number: 5186597
    Abstract: A mobile container cart includes a pivoting mechanism for pivoting the container from a horizontal position to approximately 85-90 degree vertical position. The container rests atop the cart and has removable side and top plates. A semiconductor processing equipment assembly is loaded into the container while still hot. The container is sealed and pivoted to its vertical position for transport. Once at a servicing area, the container is repositioned horizontally and the top and side plates are removed. The cart now functions as a work bench for disassembling, servicing and reassembling the device. Diagnostics can be performed while the device is in the service area.
