[0018] A high-position obstacle avoidance bracket 11 is fixed to the side wall of the outer mast 1, an obstacle avoidance radar 12 is fixed to the surface of the high-position obstacle avoidance bracket 11, and an emergency stop switch 17 is symmetrically fixed to the side wall of the outer mast 1;

A camera body 23 is fixed to the surface of the camera bracket 22. A photoelectric sensor bracket 25 is fixed to the side wall of the lower crossbeam 24. A photoelectric sensor 26 is fixed to the surface between the photoelectric sensors. The photoelectric sensor 26 is used to judge whether the goods are in place or completely separated.

[0020] The fork body 3 includes a fork bracket 31 and a fork ruler. The side walls of the fork bracket 31 are symmetrically fixed with a pallet in place mechanical switch 32. The side walls of the fork body 3 are symmetrically fixed with a fork front stopper 33. The front side walls of the fork front stopper 33 are fixed with a transition bracket 34. The rear side walls of the transition bracket 34 are fixed with a fork ruler end bracket 35. A fork tip anti-collision sensor 36 is fixed inside the fork ruler end bracket 35. The fork tip anti-collision sensor 36 is concealedly installed to prevent damage from contact with the pallet. A fork tip anti-collision sensor 37 is fixed to the lower surface of the fork tip of the fork ruler.

[0021] A camera bracket 13 is fixed to the top side wall of the outer door frame 1, and a camera 14 is fixed to the surface of the camera bracket 13. The camera 14 is used to determine whether the surrounding environment is safe.
