In every industrial facility, electric hoists are essential equipment for lifting and transporting materials safely and efficiently. However, many people are still unsure about “How many types of electric hoists are there?” and “Which type is best suited to their specific application?”

This article will answer all your questions and help you choose the right electric hoist for your application from the very beginning.

What Is an Electric Hoist?

An Electric Hoist is a lifting device powered by an electric motor, designed to safely and efficiently lift, lower, and vertically move loads. Electric hoists can be installed on various lifting systems, including Overhead Cranes, Monorail Systems, or directly mounted to building structures.

Unlike a Manual Hoist, which requires manual operation, an electric hoist is controlled by a remote control or pendant control, reducing manual effort, improving lifting speed, and supporting high-duty-cycle operations for continuous industrial applications.

How Many Types of Electric Hoists Are There?

Electric hoists can be classified into two main types based on their lifting mechanism: Electric Chain Hoists and Electric Wire Rope Hoists. Each type has its own distinct advantages and limitations, making them suitable for different lifting applications and operating requirements.

1. Electric Chain Hoist

An Electric Chain Hoist uses a hardened steel chain as the lifting medium. When not in use, the chain is collected and stored in a Chain Bag. This type of hoist is ideal for applications that require flexibility and where installation space is limited.

Key Advantages :

• Compact, lightweight, and easy to install

• Lower purchase and maintenance costs compared to wire rope hoists

• Suitable for short to medium lifting heights, typically up to 6–10 meters

• Available in capacities ranging from 125 kg to 5–10 tons

• Easy to maintain, with the chain allowing for straightforward visual inspection of wear

Limitations:

• Not suitable for very high lifting heights, as longer chains can become heavy and bulky

• Generally offers lower lifting speeds than wire rope hoists

• Not recommended for heavy-duty applications requiring high operating cycles

Recommended Applications:

Suitable for warehouses, storage facilities, automotive repair workshops, component manufacturing facilities, and small to medium-sized factories that require a compact and flexible lifting solution.

2. Electric Wire Rope Hoist 

An Electric Wire Rope Hoist uses a steel wire rope wound around a drum as its lifting mechanism. It is designed for heavy-duty applications that require high lifting speeds, greater lifting heights, and excellent durability.

Key Advantages:

• Available in high lifting capacities, ranging from 1 ton to several hundred tons

• Provides significantly greater lifting heights, making it suitable for high-rise facilities or deep lifting applications

• Higher lifting speeds than electric chain hoists, improving operational efficiency

• Designed to withstand heavy-duty and continuous operating cycles

• Ideal for use with Double-Girder Overhead Cranes

Limitations:

• Larger and heavier than electric chain hoists

• Higher purchase cost and generally requires more regular maintenance

• Wire ropes must be inspected regularly to ensure their condition and safe operation

Recommended Applications:

Suitable for steel mills, film production and assembly facilities, petrochemical industries, 24-hour manufacturing plants, and applications requiring high lifting heights or heavy load capacities.

How to Choose the Right Electric Hoist for Your Application

Choosing the right electric hoist depends on five key factors:

            1. Maximum Load Capacity (SWL)
If the load does not exceed 5 tons, an electric chain hoist may be sufficient. However, for heavier loads or applications with potential future capacity expansion, an electric wire rope hoist may be the more suitable choice.

            2. Lifting Height
For lifting heights of up to 6 meters, an electric chain hoist can be a practical solution. For applications requiring lifting heights of 10 meters or more, an electric wire rope hoist is generally more suitable.

            3. Frequency and Duty Cycle
For facilities operating 24 hours a day or applications requiring frequent lifting cycles, an electric wire rope hoist specifically designed for heavy-duty operation is recommended.

            4. Installation Space and Building Structure
For installations with limited space or where the supporting structure has limited load capacity, an electric chain hoist, with its more compact and lightweight design, can be a better option.

            5. Budget and Long-Term Maintenance Costs
Electric chain hoists generally have a lower initial cost and are easier to maintain. However, electric wire rope hoists can offer a longer service life in heavy-duty applications, making their Total Cost of Ownership (TCO) potentially more cost-effective over the long term.

How Do Electric Hoists and Cranes Work Together?

            An Electric Hoist does not operate as a standalone lifting device. It is an essential component of a crane system used for lifting and transporting materials in industrial applications.

            The hoist performs the vertical lifting and lowering of loads, while the crane moves the hoist horizontally across the working area. Together, they provide an efficient and comprehensive solution for material handling across a designated workspace.

Common Crane Systems Used with Electric Hoists

        1. Single-Girder Overhead Crane
        This type of crane is commonly used with electric chain hoists or small to medium-capacity electric wire rope hoists. It is suitable for general industrial applications involving moderate loads. Its simple structure makes it easy to install and provides a cost-effective lifting solution.

        2. Double-Girder Overhead Crane
        Designed for applications requiring higher load capacities, double-girder cranes can be equipped with both electric chain hoists and electric wire rope hoists, depending on the application. They are particularly suitable for heavy industries such as steel mills, machinery manufacturing plants, and large warehouses.

        3. Monorail System
        A Monorail System allows the hoist to travel along a fixed single rail following a predetermined path. Both electric chain hoists and electric wire rope hoists can be used, depending on the load and application. This system is suitable for production lines that require continuous and directional movement of materials between designated workstations.

Conclusion

Electric hoists and cranes work together to improve the efficiency, safety, and flexibility of lifting and material handling operations. Selecting the appropriate crane and hoist based on the application, load capacity, lifting height, duty cycle, and available workspace helps ensure optimal performance, safety, and long-term cost-effectiveness.

Frequently Asked Questions About Electric Hoists (FAQ)

Q: Are electric hoists required to undergo inspections by law?
A: Yes. Electric hoists used for lifting materials in industrial facilities are classified as “cranes” under Thailand’s Ministerial Regulation B.E. 2564. They are required to undergo inspection by a qualified and authorized inspector at least once a year. A Load Test must also be conducted before the equipment is put into service and after repairs or modifications.

Q: Which is more durable: an electric chain hoist or an electric wire rope hoist?
A: For light- to medium-duty applications, an electric chain hoist provides sufficient durability and is relatively easy to maintain. For heavy-duty applications or operations involving frequent lifting cycles, an electric wire rope hoist is specifically designed for these demanding conditions, making it a more durable and suitable long-term solution.

Q: How many phases of power does an electric hoist require?
A: Small electric hoists with capacities of up to 500 kg may be available in single-phase 220V configurations, depending on the model. However, electric hoists commonly used in industrial facilities typically operate on three-phase 380V power to provide greater operational efficiency and stability.

Q: Can I install an electric hoist myself?
A: It is strongly recommended not to install an electric hoist yourself. Installation should be carried out by qualified engineers or experienced professionals to ensure compliance with safety standards and applicable legal requirements. A Load Test should also be conducted before the hoist is put into actual operation.

Q: Is there a significant price difference between electric chain hoists and electric wire rope hoists?
A: In general, an electric wire rope hoist is more expensive than an electric chain hoist with the same rated capacity because of its more complex construction and design for heavy-duty applications. However, the actual price depends on factors such as rated capacity, lifting speed, and duty class. For the most suitable solution, it is recommended to request a quotation based on your specific application and required specifications.
