METHOD FOR LOADING/UNLOADING CARGO AND ASCENDING/ DESCENDING TYPE TAIL GATE DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for loading/unloading cargo allowing loading/ unloading cargo safely and efficiently and an ascending/descending type tail gate device for vehicle. SOLUTION: This device comprises a rotation control means 12 for controlling rotation of an auxiliary gate 9 mounted between a gate main body 8 and the auxiliary gate 9. While the gate main body 8 exists between a load-carrying platform floor face and a road surface 7, the auxiliary gate 9 is rotated downward by the rotation control means 12 for shifting it to a state to function as a bumper. As the gate main body 8 descends to have the rotation control means 12 contacted with the road surface 7, the auxiliary gate 9 is forced to rotate upward by the rotation control means 12 for shifting it to a state to allow loading/unloading cargo with being continued with the gate main body 8.
