Abstract

The Texas crash-cushion trailer, which now has wheels, is a workable and easily used implement for the protection of personnel and equipment, especially during maintenance operations on highways and streets. One crash test to verify the design theory showed that the equations of mechanics predicted results that were very close to the test results. The Texas crash-cushion trailer differs from other crash cushions in that the object supporting the crash cushion is itself movable. This means that fewer steel drums are required but also that the trailer and backup maintenance truck will travel some distance if impacted by an errant vehicle. The distance traveled after impact and the number of steel drums required are determined by equations of momentum and friction. /author/
