Technical Field

Background
Fork trucks are industrial transportation vehicles, and are various wheeled transportation vehicles that perform handling, stacking, and short-distance transportation operations on pallet goods. The traditional fork truck only relies on the driver to look into behind the fork truck in the in-process of backing a car in order to observe whether there is the barrier at the rear, when the driver sees that there is the barrier at fork truck rear and has collision risk, the driver steps on brake pedal and carries out the braking of vehicle. Because the driver may have a blind area of vision, the safety accident is easy to cause.
