More details about electric hoist

Electric hoist overview

Electric hoist is a kind of light and small lifting equipment. It has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises.

Warehouse terminals and other places. The lifting weight is generally 0.1 to 80 tons and the lifting height is 3 to 30 meters. Consisting of a motor, a transmission mechanism, and a reel or sprocket

Divided into wire rope electric hoist and electric chain hoist two. Electric chain hoist is divided into imported and domestic two; wire rope electric hoist points CD1 type,MD1 type; miniature electric hoist, hoist, multi-function hoist. 

Lifting weight: 0.25t-60t

Lift height: 3m-30m

Working level: M3

Operating speed: 20(30)m/min

Lifting speed: 8m/min

Construction of electric hoist

The components of the electric hoist are: motor, transmission mechanism, reel and sprockets. The motor and reel can be divided into four types according to their positions.

Electric hoist chart type.

(1) The electric hoist with the axis of the motor perpendicular to the axis of the reel adopts the worm gear. The width is large in size, the structure is heavy, and the mechanical efficiency is low.

, processing is more difficult. At present, no manufacturers have produced this type of structure.

(2) The electric hoist with the axis of the motor parallel to the axis of the drum has the advantage of a small height and length. The disadvantage is that the width is large and the grouping is

, Manufacturing and assembly are complicated. Large turning radius.

(3) The electric hoist mounted on the inside of the drum has the advantages of small length and compact structure. Its main drawback is poor motor cooling conditions.

Poor teamwork, inconvenience in checking, installing, and maintaining the motor. The power supply is complicated.

(4) The electric hoist mounted on the outside of the drum has the advantages of good grouping, high degree of generalization, easy change of height, installation and maintenance.

Then. The disadvantages are: large size.

Electric hoist operating conditions:

Ambient temperature: -20°C to +40°C

Work System: Intermediate JC25%

Heavy: JC40%

When the hoisting capacity of the electric hoist of the intermediate working system is reduced by 30%, it is a heavy duty working system JC40% electric hoist.

Heavy-duty work system JC40% electric hoist is used in heavy work, the load is often in the rated value or the required safety factor is high.
