During the process of lifting the goods to the target location, the obstacles around the hook of the crane may hinder the hook from various directions. The starting point of the scanning range of the laser radar is fixed as the installation point. When the laser radar emits detection laser from the fixed installation point, the space above and below the laser radar cannot be detected by the laser, thus creating a certain scanning blind area near the hook.

When the detection radar 6 tilts, the area swept by the detection laser emitted by the detection radar 6 will change. The detection range of the tilted detection radar 6 only partially overlaps with the detection range of the un-tilted detection radar 6, which expands the detection range of the detection radar 6.
