 Abstract: A new type of special equipment for food packaging automatic transportation line – elevator is designed in this paper. Special-shaped belt hoist realized the function of lifting and transporting prod-ucts by using special-shaped conveyor belt to load and transport materials,combined with the conveying prin-ciple of common belt hoist.This device had the advantages of high precision，smooth operation,low manufac-turing cost,high practicability,high automation and it will improve the efficiency greatly.This design can be used for the other types of food hoist carrying different load-bearing objects, and lower the difficulty of designing machine. So, it has a wide range of applications．
