1. A combination cot loading and fastening system for loading and unloading an ambulance cot into an emergency rescue vehicle, the vehicle having an opening providing access to the transport deck, said system comprising: a pair of tracks mountable to the transport deck of the emergency vehicle and having a first and second ends, and a longitudinal length extending from the first end to second end, said second end being located adjacent but inward of the opening of the vehicle, said tracks having opposing channels;a shuttle assembly engaged for movement in said opposing channels of the pair of tracks and configured to securely pull the ambulance cot along the pair of tracks, the shuttle assembly comprising a frame having a first end, a second end, and a longitudinal body extending from the first end to the second end; anda locking mechanism mounted on said shuttle assembly and configured to releasably hold the ambulance cot, wherein the shuttle assembly is configured to position the locking mechanism a distance away from the second end of the pair of tracks and at an angle below the transport deck of the emergency rescue vehicle; andwherein said shuttle assembly provides three points of attachment to the ambulance cot. 2. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly includes a carriage frame having the first end, the second end, and the longitudinal body, said shuttle assembly also includes two pairs of stabilizer bars, a pair of lifting cylinders, and a three point attachment yoke assembly mounting said locking device as one of three attachment points. 3. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly comprises a three point attachment yoke assembly mounting said locking device as one of three attachment points, and a pair of upright supports mounted on said longitudinal body at said first end, said upright supports each pivotably mount a pair of stabilizer bars and a lifting cylinder, said stabilizer bars of each upright support being pivotably mounted to said shuttle assembly, and wherein said lift cylinders of the pair of upright supports are configured to lift the yoke assembly. 4. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly comprises a three point attachment yoke assembly mounting said locking device as one of three attachment points, and a pair of upright supports mounted on said longitudinal body at said first end, said upright supports each pivotably mount a pair of upper and lower stabilizer bars and a lifting cylinder mounted therebetween, said upper and lower stabilizer bars of each upright support being pivotably mounted to said shuttle assembly, and wherein each lift cylinder is pivotably mounted to the lower stabilizer bar and is configured to lift the yoke assembly. 5. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly comprises a three point attachment yoke assembly mounting said locking device as one of three attachment points, and a pair of upright supports mounted on said longitudinal body at said first end, said upright supports each pivotably mount a pair of stabilizer bars and a lifting cylinder, said stabilizer bars of each upright support being pivotably mounted to said shuttle assembly, wherein said lift cylinders of the pair of upright supports are configured to lift the yoke assembly, wherein the upright supports remain inside the opening of the vehicle, and do not extend outwardly therefrom. 6. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly includes two pairs of stabilizer bars, a pair of lifting cylinders, and a yoke assembly, wherein the yoke assembly includes two substantially parallel arms separated and mounted to a head frame, said head frame mounts said locking mechanism to provide a first point of attachment to the ambulance cot at a front end and said parallel arms provide two additional points of attachment to the ambulance cot on sides thereof. 7. The combination cot loading and fastening system according to claim 1 wherein said shuttle assembly includes two pairs of stabilizer bars, a pair of lifting cylinders, and a yoke assembly, wherein the yoke assembly includes two substantially parallel arms separated and mounted to a head frame, said head frame mounts said locking mechanism to provide a first point of attachment to the ambulance cot at a front end and said parallel arms provide holds for engaging side extension arms of the ambulance cot to provide two additional points of attachment to the ambulance cot.
