Abstract: The system for capturing a vehicle is a device, which is mounted on the front of a first vehicle for deploying a grasping hook for grasping the rear bumper of a second vehicle. In operation, the system begins in a locked configuration, with a hook member being positioned rearward with respect to a lower shaft. When the first vehicle brings an actuating arm in contact with the rear bumper of the second vehicle, pressure on the actuating arm generates rotation in the upper shaft. This rotation of the upper shaft causes disengagement of the lower end of an engaging member from a recess formed in a disc mounted on the lower shaft, causing the resiliently biased lower shaft to rotate. Rotation of the lower shaft rotates an elongated hook support and the hook member into the deployed configuration, with the hook member grasping the rear bumper of the second vehicle.
