Air hoist vs Electric hoist

Air hoist vs Electric hoist

1. Different working principles

2. Different volumes

3. Different load capacities

4. Different lifting speeds

5. Different working accuracy

6. Different safety performance

7. Different application areas

Some of the lifting equipment used on the market, the most common ones are pneumatic chain hoist and electric hoist. I believe many people don’t know the difference between these two lifting equipment. During my years in the industry, customers often hesitate to choose pneumatic hoist. Hoist or electric crane hoist, because there is not much difference in the range of use and price between the two hoists. In order to clearly distinguish the difference between the two and provide you with some purchasing suggestions, we have compiled them as follows:

1. Different working principles:

The dynamics of the two devices are different. The pneumatic air hoist uses air as the driving force, and the driving motor drives the internal mechanical components to meet the working requirements of lifting heavy objects. Since it does not require power to drive, it has explosion-proof functions.

Electric crane hoist is the electrical energy used to make the equipment work through voltage.

2. The volume is different.

The electric hoist is relatively large and requires many internal components to prevent sparks, while the pneumatic chain hoist uses a pneumatic motor, which is small and easy to use.

3. Different load capacities:

Pneumatic hoist has a minimum load capacity of 250kg and a maximum load capacity of 100 tons.

Electric hoist has a minimum load capacity of 490kg and a maximum load capacity of 30 tons.

If the load capacity is not too large, you can choose an electric hoist; if the load capacity is large, you should choose a pneumatic air hoist.

4. Different lifting speeds:

There is also a difference in the operating speed of the two devices. The fastest lifting speed of a pneumatic hoist is generally 17m/min, which is almost four times that of an electric crane hoist. Moreover, its running speed can still be adjusted. If we are lifting at high altitude, we can adjust the running speed slower. , making the operation of the equipment safer.

5. The working accuracy is different:

The positioning accuracy of the pneumatic air hoist is at the centimeter level, while the accuracy of current electric hoists can reach the millimeter level;

6. Different safety performance:

The pneumatic chain hoist is relatively safe. It uses air as the driving force. It will not produce sparks during use, and there will be no electric shock. It is a relatively advanced explosion-proof equipment. The electric hoist is driven by electric energy. During use, It is prone to leakage and electric shock, may produce sparks, and is a high safety hazard.

7. Different application fields:

Because of its explosion-proof function, pneumatic hoists are widely used in flammable, explosive, high-temperature (can work normally at high temperatures above 60 degrees), high-dust, and highly corrosive workplaces, such as: chemical industry, petroleum and coal mines, oil storage, and shipbuilding.

Electric crane hoist is widely used in the presence of power supply, equipment maintenance and machinery hoisting, such as shot blasting machines, machining workshops, foundries, etc.

If you compare pneumatic air hoist and electric hoist carefully, there are still many differences. Pneumatic hoist does not require professional maintenance because it is more reliable in terms of safety and use, but electric hoist Hoists are different. Electric hoists require inspection and maintenance by professional personnel, otherwise safety problems are likely to occur. This is also the most obvious difference between the two. Therefore, pneumatic hoists are used more than electric hoists on the market.

Pneumatic hoist:

Pneumatic air hoist is a lifting equipment that uses compressed air as the working medium and converts the pressure energy of compressed air into mechanical energy to lift goods. It is mainly composed of five parts: air motor part, deceleration mechanism, air circuit control, braking mechanism and lifting mechanism.

In addition, the pneumatic hoist also has an overload protection function. Once the rated load is exceeded, it will automatically stop working, effectively avoiding lifting accidents. It is widely used in petroleum, chemical industry, coal mines, textiles, warehousing, household appliance production lines, automobile manufacturing production lines, shipbuilding and other industries. It is an indispensable and important equipment for enterprises to produce safely, improve efficiency and reduce costs.

Electric hoist:

An electric hoist is a device used to lift and carry heavy objects. It consists of a motor, a transmission mechanism, a drum or a sprocket. It is divided into two types: wire rope electric hoist and chain electric hoist.

It is a kind of lifting equipment, generally installed on single-girder cranes, bridge cranes, gantry cranes, and suspension cranes. The electric hoist has the characteristics of small size, light weight, simple operation, and easy use. It is used for lifting and hauling. , loading and unloading heavy objects, flip-chip welding of oil tanks, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment, suitable for construction and installation companies, civil engineering and bridge construction in factories and mines, electric power, ships, automobile manufacturing, Mechanical equipment for infrastructure construction projects such as buildings, highways, bridges, metallurgy, mines, slope tunnels, and shaft management and protection.
