Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing, and more specifically to an alarm device for preventing a logistics shelf from being collided with a forklift. Background Art

[0002] Currently in the process of logistics and warehousing, shelves have become carriers for stacking goods. Since the goods are heavy, in order to improve the efficiency of stacking, forklifts are often used to stack the goods on the shelves and achieve stacking of goods at high positions.

[0003] During warehousing operations, when forklifts are transporting goods, they often collide with shelves because the height of the goods is blocking the forklift driver's view. Collision accidents can cause shelf deformation and damage to goods at the least, or serious deformation of shelves, resulting in shelf collapse, mechanical fracture and other serious problems. Therefore, how to avoid collisions has become an urgent problem to be solved during forklift transportation.

[0004] In view of this, we propose an alarm device for preventing forklift collision on logistics shelves. Utility Model Content
