Abstract
A backup system is provided for a gate screw assembly of a race car transport trailer. The gate screw assembly includes a pair of screws which are rotated by an electric motor and interconnecting linkage arms so as to raise and lower the gate. The backup system includes rotatable shafts operatively connected to the drive shaft of the motor. Upon failure of the motor, the shafts of the backup system can be rotated by a drill or a wrench, thereby rotating the motor drive shaft, the linkage arms, and the gate screws, so that the gate can be moved between the raised and lowered positions.
