Abstract:

The usefulness of the air-bearing principle in moving heavy loads over relatively smooth surfaces has been demonstrated. The ability of a flexible seal to permit movement over significant obstacles, such as a 4-inch lower-hold brow, with adequate stability and acceptable efficiency was investigated. Two experimental 5 ton CONEX container jacks were constructed to permit seal evaluation under operational conditions. Since the air requirements fell in a pressurevolume range for which few sources were available, the expedient of employing a roots type blower to satisfy the requirements introduced inordinate noise problems which are now the subject of investigation before operational tests are conducted. The attached report describes the operation, maintenance, and construction details of the device, including some cost information for producing a device of this sort.
