Know "electric hoist"

The 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, storage terminals and other places. The lifting weight is generally 0.1 to 80 tons, and the lifting height is 3 to 30 meters. It is composed of a motor, a transmission mechanism, and a reel or sprocket, and is divided into two types: wire rope electric hoist and electric chain hoist. Electric chain hoist is divided into two kinds of imported and domestic; 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

Electric hoist main structure

Reducer, hoisting motor, running motor, fire breaker, cable slip, reel device, hook device, coupling, soft cable current introducer and so on gather power and brake force in one.

Electric hoist installation use:

Electric hoist single-girder cranes, bridge cranes, gantry cranes, hanging cranes on the upgrade, can also be used for winding. Therefore, it is an essential machinery to improve labor efficiency and improve working conditions.

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. Electric hoist structure reducer: The use of three-stage fixed shaft helical gear rotation mechanism, gear and gear shaft made of heat-treated alloy steel, box, box cover made of high-quality cast iron, tight assembly, good sealing. The reducer is a self-contained part that is extremely easy to load and unload.

Control box: It adopts the device that can cut off the main circuit in case of emergency, and has the up and down stroke protection fire stop. Ensure the safe operation of the electric hoist. Electrical components have long life and reliable use.

Wire Rope: The GB1102-74(6*37+1)X type lifting rope is used to ensure durability.

Cone row motor: The hoist motor adopts a conical rotor brake asynchronous motor with large starting torque, and no external brake is required. The motor load continuation rate is 25%. The motor uses Class B or Class F insulation and the motor protection class is IP44/IP54.

Electric hoist classification

Electric hoist main categories: electric chain hoist, wire rope electric hoist (explosion-proof hoist), anti-corrosion electric hoist, chain electric hoist, double drum electric hoist, hoist, multi-function hoist.

Button switch: Hand operation is light and flexible, sub-rope operation and wireless remote control are two ways.
