A power screw load retention system is described. The system typically includes four power screw sections each having a threaded shaft connected to a power source located within an elongated channel. A carriage is in threaded engagement with the threaded shaft and is adapted to translate within the channel. The carriage is connected to a connecting member such as a chain that connects to the under structure of a vehicle. Typically, the four power screw sections are located on a platform that holds the vehicle. Several of these platforms are located on a vehicle transporter. All of the power sources may be connected to a control unit.
