What Is Electric Chain Hoist

Types of Deep Digging Electric Chain Hoists：

• Classification by structural type：
  

1. Fixed type：The structure is relatively simple, the stability is good, and it is suitable for lifting heavy objects in a single working area.
   

2. Running style：It can move within a certain range and is usually equipped with a trolley that can walk on tracks, increasing the flexibility of work.

3. Climbing style：It is specially designed for operations on vertical or inclined surfaces and is often used in construction and other occasions.

• Classification by lifting speed:

1. Single speed type:  There is only one fixed lifting speed, which is suitable for regular lifting operations.

2. Two-speed type： It has two lifting speeds, generally divided into fast and slow, which can be switched according to actual needs to improve work efficiency.

3. Frequency conversion type：The motor speed is controlled by the frequency converter to achieve stepless speed regulation, which can more accurately control the lifting speed and is suitable for occasions with high lifting speed requirements.

• Classification by power type：

1. Three-phase AC type：It has strong power and is suitable for large electric chain hoists or occasions with high power requirements.

2. Single-phase AC type：The power supply is easy to access and is commonly used in small electric chain hoists. It is suitable for homes or some single-phase power supply environments.

3. DC type： It is usually powered by batteries, has a certain degree of mobility, and is suitable for some occasions where AC power cannot be accessed.

• Classification by application scenario：

1. Ordinary industrial type： Used for material handling and lifting in conventional industrial places such as factory workshops and warehouses.

2. Explosion-proof： It has explosion-proof performance and is suitable for dangerous environments such as petroleum, chemical industry, mining, etc. where flammable and explosive gases or dusts exist.

3. Clean type： It meets the demanding production environment requirements of electronics, pharmaceuticals, bioengineering and other fields, and has dust-proof and anti-static properties.

4.  Stage type： Used for installation and debugging of stage lighting and sound equipment, it has the characteristics of small size, light weight and stable operation.

• Classification by chain quantity：

1. Single-chain style： It uses a single chain to lift heavy objects, and its structure is relatively simple, suitable for lifting lighter loads.

2. Double-chain style： Lifting with two chains has a stronger load-bearing capacity and better stability, and is often used to lift heavier objects.
