As the core lifting mechanism in lifting equipment, the electric hoist is widely used in overhead cranes, jib cranes, and various light-duty lifting devices, undertaking critical tasks such as material handling, equipment installation, and production line operations. Its performance and reliability directly affect the operating efficiency and safety of the entire lifting system. In practical applications, improper selection of an electric hoist may result in unstable operation, reduced productivity, or even safety risks. It can also increase maintenance requirements and operating costs over time, negatively impacting normal production activities. Therefore, selecting the right electric hoist based on specific working conditions is particularly important.
At present, the chain hoist and the wire rope hoist are the two most widely used types of electric hoists in industrial applications. Each has its own advantages in terms of structural characteristics, load capacity, and application scenarios. A clear understanding of their differences is essential for achieving safe and efficient lifting operations.
Chain Hoist Overview
Working Principle and Structural Features
Working principle: A chain hoist uses a high-strength lifting chain as the load-bearing element. The motor drives a reduction mechanism, allowing the chain wheel to circulate the lifting chain to raise or lower the load.
Structural features: It mainly consists of a motor, gearbox, chain wheel, lifting chain, hook, and control system. The compact structure and small installation footprint make it particularly suitable for confined spaces or applications requiring precise handling.
Typical lifting capacity: Chain hoists are generally used for light to small-medium lifting operations, with common capacities ranging from 0.5 to 5 tons. Although special designs can achieve higher capacities, industrial applications are mainly focused on light and medium-duty conditions.
Key Advantages of Chain Hoists
▴Simple structure and low self-weight, making installation and maintenance convenient.
▴Smooth lifting motion and sensitive braking, enabling accurate positioning—ideal for assembly lines, equipment maintenance, and mold handling where precision is critical.
▴Relatively low maintenance workload and lower routine inspection costs.
Limitations of Chain Hoists
▴Due to limitations in chain length and transmission method, chain hoists have relatively restricted lifting height and speed, making them unsuitable for large lifting heights or high-frequency, high-speed operations.
▴For applications requiring long travel, heavy loads, or continuous high-efficiency operation, a wire rope hoist is generally a better choice.
Wire Rope Hoist Overview
Working Principle and Main Components
Working principle: A wire rope hoist uses steel wire rope as the load-bearing and traction element. The motor drives the drum to rotate, winding or unwinding the wire rope in an orderly manner to raise or lower the load.
Main components: Key components include the lifting motor, reducer, drum, wire rope, pulley block, hook, and electrical control system. This design offers high transmission efficiency and uniform load distribution, making it suitable for heavier loads and intensive operations.
Typical lifting capacity: Wire rope hoists are designed for medium to heavy-duty lifting, with common capacities ranging from 3 tons up to 100 tons or more. They can be customized according to actual working conditions and are widely used in over
Core Advantages of Wire Rope Hoists
▴Compared with chain hoists, wire rope hoists offer higher lifting capacities and faster lifting speeds, making them well suited for high-frequency and continuous-duty applications.
▴Smooth operation and high efficiency, ideal for industries such as steel manufacturing, machinery production, and warehousing and logistics where productivity and load capacity are critical.
Limitations of Wire Rope Hoists
▴The structure is relatively more complex, requiring higher standards for installation, commissioning, and maintenance.
▴Components such as wire ropes, pulleys, and drums require regular inspection and replacement, resulting in higher overall maintenance costs compared with chain hoists.
▴When selecting a wire rope hoist, factors such as operating frequency, maintenance conditions, and long-term operating costs must be carefully evaluated.
Core Comparison Between Chain Hoists and Wire Rope Hoists
In practical lifting applications, chain hoists and wire rope hoists each demonstrate advantages under different working conditions. There are clear differences between the two in terms of load capacity, structural design, operating efficiency, and maintenance requirements. Properly understanding these core distinctions helps improve operating efficiency and control overall costs while ensuring safety.

Selection Recommendations for Different Application Scenarios
In real engineering and industrial projects, electric hoist selection should comprehensively consider factors such as working environment, lifting capacity, operating frequency, and safety requirements. Different scenarios emphasize different performance priorities. Proper selection not only improves efficiency but also reduces failure rates and total life-cycle costs.

Key Parameters and Considerations for Electric Hoist Selection
In practical engineering applications, selecting an electric hoist in a scientific and well-structured manner requires a comprehensive evaluation of multiple key parameters to ensure lifting operations are safe, reliable, and cost-effective.
Rated Capacity and Safety Factor
Definition
The rated capacity refers to the maximum load an electric hoist can safely lift, while the safety factor indicates the hoist’s ability to operate safely under rated load conditions.
Selection recommendations
When selecting a hoist, sufficient capacity margin should be reserved based on actual load requirements. In general, the rated capacity should be 1.25–1.5 times the actual working load, ensuring safe operation under occasional overloads or dynamic loads.
Notes
Never select a hoist with a rated capacity close to or lower than the actual working load, as this may lead to safety incidents and equipment damage.
Lifting Height and Duty Class
Lifting height
Determines the required chain length or drum size, directly affecting travel design and overall equipment dimensions.
Duty class
Defined by FEM and ISO standards, the duty class specifies allowable operating frequency and duration.
Selection recommendations
▴Short lifting height and intermittent operation → lower duty class hoist
▴Long lifting height and continuous, high-frequency operation → higher duty class hoist
Notes
Ensure the chain length or drum capacity fully meets the maximum lifting height to avoid over-travel or unsafe operation.
Voltage, Control Method, and Protection Rating
Voltage
Select according to the crane system and site power supply. Common industrial voltages include 380V, 400V, 415V, 440V, and 690V.
Control method
Options include push-button control, pendant control, wireless remote control, or variable frequency drive (VFD) control. The choice affects operational flexibility and safety.
Protection rating
The IP rating defines dust and water resistance, determining suitability for different environments.
Selection recommendations
▴Indoor environments: standard protection rating
▴Outdoor or harsh environments: higher IP rating and corrosion-resistant materials
Notes
Ensure the control system is compatible with the crane type and operating habits, while fully complying with applicable safety standards.
Compatibility with Overhead Cranes or Single-Girder Cranes
Requirements
The electric hoist must match the crane type, span, lifting height, and load capacity.
Selection recommendations
▴Single-girder cranes: suitable for light to medium-duty chain hoists or small-capacity wire rope hoists
▴Double-girder cranes: suitable for medium to heavy-duty wire rope hoists, meeting high-capacity and high-frequency requirements
Notes
Improper matching may result in unstable crane operation, abnormal structural loading, and even serious safety risks.
