Due to the effects of rain and freeze-thaw alternation, rockfall occurs from time to time on the slope. The falling rocks pose a great hidden danger to the driving safety of vehicles on the road, especially on high-grade routes such as expressways and first-class highways. The amount of falling rocks is small and the scattered area is large, and the falling rocks on the slope must be cleaned up regularly; some outdoor rock walls are steep, and the operating conditions for manual cleaning of falling rocks are difficult, and the safety hazards are huge. Therefore, it is necessary to develop a rock-dropping device that is suitable for high rock walls.
