Electric chain hoists are a type of light and small lifting equipment. They consist of an electric motor, transmission mechanism, and sprocket, and use chains as the lifting medium to achieve vertical or horizontal movement of the load. Compared with wire rope electric hoists, electric chain hoists have the advantages of small size, light weight, simple structure, easy operation, and easy maintenance. They are suitable for use in factories, warehouses, docks, construction sites, and other places. The lifting parameters of electric chain hoists mainly include lifting capacity, lifting height, lifting speed, and working level. Lifting capacity refers to the maximum load that an electric chain hoist can safely lift. Lifting height refers to the distance that an electric chain hoist can lift a load from the lowest point to the highest point. Lifting speed refers to the rate at which an electric chain hoist lifts or lowers the load. The working level of an electric chain hoist is an internationally recognized value defined based on the working frequency and duration of the electric hoist under its rated load. The working level classification standards for electric hoists include M3, M4, M5, M6, M7, and M8. The higher the level, the greater the workload of the motor, the better the motor performance, and the longer the service life. Our electric hoists are generally at level M5, featuring simple operation, light weight, stable performance, and long service life.
The design features of the electric chain hoist mainly include the following points:
It uses high-strength, anti-aging, and wear-resistant round steel chains as the lifting medium, which have good safety and reliability.
It adopts high-performance, low-noise,e and long-life motors as the driving power source, which has a high safety margin and a high duty cycle.
It uses advanced, precise, and durable transmission mechanisms, including helical gear meshing gearboxes, friction clutches and brakes, etc., to achieve smooth operation and overload protection.
It uses a 24V contactor control system,d travel limit switches, and other electrical control devices to achieve safety-related functions and operational convenience.
The external components, such as the sturdy, lightweight,t and aesthetically pleasing aluminum housing and plastic chain collection box alsoox achieve dust-proof, water-proof, oof and shock-resistant properties.
According to different usage scenarios and requirements, electric chain hoists can be classified into the following types:
Fixed type: The fixed type electric chain hoist is fixed on a fixed support point and can only perform vertical lifting operations, suitable for smaller work areas.
Running type: The electric trolley chain hoist is installed on a small cart that can move horizontally along a track, allowing for both vertical and horizontal lifting operations, suitable for larger work areas.
Low headroom type: The motor and gearbox of the electric chain hoist are installed on the same side, reducing the hook size C and increasing the headroom, suitable for lower work areas.
Double chain type: Two electric chain hoists are installed on the same cart, using two mechanically synchronized chains to achieve lifting operations of long objects or beams.
Explosion-proof type: All components of the electric chain hoist are designed and made of explosion-proof materials, allowing lifting operations in places with explosive gases or dust.
We are a leading hoist manufacturer in China. Besides the electric chain hoist, we also produce wire rope hoists, air hoists, winches, etc. For any needs, please feel free to contact us!
