Heavy Duty Electric Chain Hoist for Industrial Lifting

The DHA is designed as a heavy duty electric chain hoist for applications that require powered lifting, stable load control and reliable operation. The electric lifting system reduces manual effort and improves productivity in repetitive lifting tasks compared with manually operated lifting equipment.

With capacities from 500 kg to 7.5 ton, the DHA series can handle a broad range of industrial loads. It can be used for machinery installation, equipment maintenance, component lifting, production-line handling, warehouse operations and general material handling.

Fixed Electric Chain Hoist and Traveling Electric Chain Hoist

The DHA Series is divided into two main configurations: fixed electric chain hoistandtraveling electric chain hoist. This allows users to select the appropriate lifting solution according to the required load movement and installation structure.

Fixed Electric Chain Hoist

The fixed configuration is suitable for lifting and lowering loads from a stationary lifting point. It can be used for workshop lifting, machinery maintenance, equipment installation, production equipment servicing and fixed-position material handling.

Traveling Electric Chain Hoist

The traveling configuration is equipped with an electric trolley for horizontal movement along a compatible I-beam. The trolley system allows suspended loads to be lifted and transported horizontally within the working area, making it suitable for production lines, workshops, warehouses and industrial lifting systems.

The specified I-beam range varies according to the hoist model, from approximately 68–153 mm to 112–178 mm. The actual trolley and beam configuration should be selected according to the application and technical requirements.

High-Strength G100 Alloy Steel Chain

The DHA Series Electric Chain Hoist uses a G100 high-strength heat-treated alloy steel chain. The chain is a critical load-bearing component of an electric chain hoist, and the high-strength alloy steel construction is designed to provide reliable performance under repeated lifting loads.

Depending on the model, chain diameters range from 6.3 mm to 11.2 mm. The corresponding chain specification is selected according to the rated lifting capacity and hoist configuration.

Aluminum Alloy Motor with Efficient Heat Dissipation

The DHA lifting motor features an aluminum alloy stretched housing designed to improve heat dissipation. Efficient thermal management is particularly important for electric lifting equipment used frequently in factories, workshops and production environments.

The lifting motor is specified with IP55 ingress protection and Class F insulation. Depending on the model, lifting motor power ranges from 1.1 kW to 3.0 kW, with a rated rotation speed of 1440 r/min.

High-Strength Aluminum Alloy Gearbox

Thealuminum alloy gearbox uses an integrated die-casting structure designed to combine strength with reduced housing weight. The aluminum alloy construction also provides good corrosion resistance and contributes to efficient heat dissipation.

The robust gearbox supports the transmission system of the industrial electric chain hoist, helping provide stable lifting performance during regular material handling operations.

Electromagnetic Brake for Reliable Load Control

The DHA Series incorporates an electromagnetic brake device designed to provide rapid braking when the power supply is cut off. The braking system works together with the lifting mechanism to help control suspended loads during normal lifting and lowering operations.

The electromagnetic brake is particularly important for industrial lifting equipment because controlled stopping and load holding are essential when positioning machinery, equipment and other suspended loads.

Upper and Lower Limit Switch Protection

Theupper and lower limit switch system helps control the lifting motor and automatically stop operation when the chain reaches the designated limit. This helps prevent excessive chain travel and provides an additional layer of protection for the electric hoist.

The compact upper limit switch design also helps maximize the effective lifting range while maintaining the necessary protective function of the hoist.

Phase Sequence Protector and 36V Control System

The DHA electrical system includes a phase sequence protector. When the incoming power connection has an incorrect phase sequence, the control circuit will not operate, helping reduce the risk associated with incorrect electrical connection.

The control circuit uses 36V low-voltage control, providing an additional electrical safety measure for routine operation. Electrical installation and connection should always be completed by qualified personnel according to applicable requirements.

Alloy Steel Forged Hooks with 360° Rotation

The DHA electric chain hoist is equipped with alloy steel forged hooks designed for high-strength load attachment. The hooks feature an anti-detaching safety device and can rotate 360 degrees, providing greater flexibility when attaching and positioning suspended loads.

The forged hook construction is designed for demanding lifting applications and provides a secure connection between the hoist and compatible lifting accessories.

Applications of DHA Electric Chain Hoist

The DHA Series is suitable for a wide range of industrial lifting and material handling applications. The appropriate capacity and configuration should be selected according to the load, lifting height, working environment, installation structure and operating requirements.

Electric Chain Hoist for Factory and Warehouse Operations

In factories and warehouses, repetitive lifting can consume considerable time and physical effort. The electric chain hoist provides powered lifting to make routine load handling more efficient.

The traveling version further expands the working range by allowing loads to move horizontally along an appropriate I-beam. This makes it useful for warehouse lifting systems, workshop cranes, production lines and industrial material handling stations.

Wide Capacity Range from 0.5 to 7.5 Ton

One of the major advantages of the DHA series is its broad capacity range. Models are available from 0.5 ton, 1 ton, 1.5 ton, 2 ton, 2.5 ton, 3 ton, 5 ton and 7.5 ton.

Different models also provide different lifting speeds, allowing buyers to select an appropriate configuration according to lifting capacity and operational requirements. Lifting speed in the listed models ranges from 1.8 to 7.2 m/min.

How to Select the Right Electric Chain Hoist

When selecting a heavy duty electric chain hoist, buyers should consider several technical factors, including rated load, lifting height, lifting speed, power supply, working frequency, installation method and whether horizontal load movement is required.

• Rated Capacity: Select a capacity suitable for the maximum intended load.
• Lifting Height: Choose the required 3 m or 9 m configuration according to the lifting application.
• Lifting Speed: Select the appropriate speed based on productivity and load positioning requirements.
• Fixed or Traveling: Choose a fixed hoist for stationary lifting or a traveling type when horizontal load movement is required.
• I-Beam Size: For trolley models, confirm that the I-beam dimensions match the applicable trolley range.
• Power Supply: Confirm voltage, frequency and electrical configuration before installation.
• Working Environment: Consider operating conditions, lifting frequency and environmental requirements when selecting the appropriate configuration.
