Structural Characteristics and Different Types of European-style Electric Hoists

European-style electric hoist can be divided into two types: chain type and wire rope type, according to different types, their lifting parameters, working levels and use environment are also different.

The chain type European electric hoist is an electric hoist that uses a high-strength chain as the lifting medium, its lifting parameters are generally 0.25-20 tons, and the working level is M4-M6, which is suitable for light and medium-sized industrial production or logistics and transportation. The European electric chain hoist has the advantages of small size, low noise, stable operation and flexible operation.

Wire rope type European electric hoist is a kind of electric hoist that uses high-strength wire rope as the lifting medium, its lifting parameters are generally 1-50 tons, and the working level is M5-M8, which is suitable for medium and heavy industrial production or large-scale logistics and transportation. The wire rope type European electric hoist has the advantages of large load, fast speed, high headroom and long life.

The structure of the European electric hoist is mainly composed of a motor, a transmission mechanism, a drum or a sprocket, which can be divided into four types according to the relative position of the motor and the drum or sprocket:

(1) The electric hoist with the motor axis perpendicular to the reel or sprocket axis adopts worm gear transmission device, which has a rough structure and low efficiency, and has been rarely used.

(2) The electric hoist with the motor axis parallel to the reel or sprocket axis adopts helical gear transmission device, which has a compact structure, a large width and a large turning radius.

(3) The electric hoist with the motor installed inside the drum or sprocket adopts a planetary gear transmission device, which has a simple structure and a small length, but the heat dissipation conditions are poor and the maintenance is inconvenient.

(4) The electric hoist with the motor installed outside the drum or sprocket adopts a cylindrical gear transmission device, which has reasonable structure, high versatility and convenient maintenance.
