The invention discloses a system and method for alignment and safety control of trucks under bridge cranes of container wharves. Through a rotating platform, a laser scanner, a system operation control unit and an LED display screen, the accurate identification of the deviation distance between the position of a truck and the benchmark lifting point of an offshore bridge is realized, and the direction of the truck deviating from the lifting point of the offshore bridge and the distance information are displayed on the LED display screen to prompt the driver of the truck to adjust the truck parking position; meanwhile, the operation control unit is connected with a PLC to obtain the type information of the container which runs at present so as to realize the guidance of the truck parking position; a control system of the PLC judges whether the truck is in place through the interface, and controls a lifting device to keep a safety height and forbids the lowering action of the bridge lifting driver when the truck is not aligned so as to prevent the truck from being damaged by the lifting device.
