Rubber Tired Gantry crane (RTG) Approach Detection

It detects surrounding obstacles to prevent collisions with trucks and containers during container transshipment work with port cranes.

LiDAR is installed on four piers of the crane to detect obstacles in the direction of travel.
It was adopted because it is easier to set the detection area than the ultrasonic sensor, and the area can be switched between the front and back direction and the horizontal direction.
