ABSTRACT:
A load-carrying vehicle has either an air-impermeable load platform or an air-impermeable sheet over the platform and has a further air-impermeable sheet put over the goods on the platform. Continuous extraction of air from within the sheet, despite possible leakage of air into the sheet around its periphery, causes a significant reduction in pressure so that the sheet holds the goods onto the platform.
