Abstract
Abstract A fixed utility cabinet houses various utility conduits, e.g., electricity, gas, water, etc. The upper part of the front of this utility cabinet is a solid panel while the lower part has openings closed by access doors. Immediately to the front of the utility cabinet is a table top secured to vertically telescopic supports. The supports rest on feet extending under the table top. The table top can be moved up and down substantially within the range defined by the solid front of the utility cabinet. Various forms of storage cabinets can be hung below the table top and spaced above the floor, with these storage cabinets moving vertically in unison with the table top. A wheeled cart having a hydraulic lift is used to facilitate securing the cabinets below the table top and for raising and lowering the table top.
