LOAD TRANSPORTATION DEVICE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; air cushion transportation devices for movement over nonprepared floors or machine building plants. SUBSTANCE: compressed air is delivered to supports 3. Diaphragms of aerostatic supports 3 inflate and, thrusting against rigid plates 5 lift platform 1 with load 2. When reaching any periphery portion of each plate, diaphragm of support 3 gets behind recesses 7. This leads to sharp increase in air consumption, and pressure under diaphragm of support 3 drops. Relay cuts off compressed air delivery to aerostatic supports, and platform 1 with load 2 is set on stop 4. Springs 6 align all plates 5 relative to center of supports 3. Then compressed air is again fed into supports 3, and following cycle of device movement is executed. EFFECT: simplified design, improved operating characteristics. 4 dwg
