TECHNICAL FIELD

[0001] The present application relates to the technical field of transfer equipment, in particular to a water-falling-preventing device for wharf cargo loading and unloading. BACKGROUND

[0002] The wharf is a building for ships or ferries to berth, for passengers to get on and off, and for cargo to be loaded and unloaded, which is usually found in commercial cities with developed water and land transportation. During the cargo loading and unloading at the wharf, the cargo often falls or the workers fall into the water, and the falling cargo may directly fall into the water, causing economic losses and environmental pollution. Meanwhile, when the workers carry the cargo, especially in a tired state, there is a risk of falling, which threatens the safety of the workers.
