Using a Tail Gate can make it unnecessary to use machinery such as a forklift to load heavy items on to a vehicle. A Tail Gate can also bridge the difference in height between a loading dock and the vehicle load bed. Some types of Tail gates are: Parallel Arm, Rail-gate, Column Lifts, Cantilever, Tuck-under and slider Lift gates
