ABSTRACT:
Improvements to the various components of hydrostatic bearing levitation systems, systems wherein fluid pressure between a load and the rails of a track system supports and guides the load, are described. The rail has a plurality of lengthwise extending ports and nozzles communicating from the innermost ports through the curved upper wall to the interface area between the rail and the load. The nozzles are arranged in longitudinally aligned groups and in a pair of parallel rows with the groups of one row being longitudinally staggered with respect to the groups of the other row. The nozzles can be inexpensively produced by boring an oversize hole through the upper wall and fixing a cannula, such as a hypodermic needle, in the bore. The cannula's internal diameter is the desired nozzle diameter. The load support member has a compliant outer cover, a central core, and a filler material wound tightly on the core. The filler material is a cellulosic sheet material having a high percentage of groundwood and little or no crepe. The improved components cooperate together to provide a low-cost load/mover whether for palletized loads in a warehouse or even for inter- or intra-urban transportation systems.
