ZKKN premium electric chain hoists are 中科重工‘s latest high-end electric chain hoist series. Compared to HHBB standard electric chain hoists and ZKE中型电动链式起重机, they occupy less space and have a higher lifting height. Their biggest advantage lies in dual-speed lifting, resulting in more precise positioning and higher work efficiency. They can be easily installed on suitable light and small lifting equipment, such as cantilever cranes or KBK cranes, and are widely used in automotive assembly lines, wind power equipment maintenance and repair, precision manufacturing workshops, and other operations, making them your best choice for safety and quality.

Product Features of ZKKN Premium Electric Chain Hoists
- Dual-Speed Lifting: Supports high and low speed lifting modes, providing efficient and stable high-speed lifting and precise and controllable low-speed positioning, balancing work efficiency and assembly precision to meet the needs of various precision assembly scenarios.
- Multiple Safety Protections: Built-in friction clutch, fine-tuning limit switch, and motor overheat protection, combined with a sealed electro-disc brake, prevent overload and overtravel, providing timely and sensitive response, and comprehensive safety protection.
- Heavy-Duty Durable Body: Working class up to M6, insulation class H, IP55 protection rating, and a duty cycle of up to 60%.
- Universal Suspension Adaptability: Equipped with new suspension lugs, it can adapt to various connection structures and is perfectly compatible with KBK and other lifting equipment, offering wider installation adaptability and meeting diverse working conditions.
- Low-Noise and Smooth Operation: Equipped with a new sealed reducer with gear precision of level 7 or higher, resulting in low operating noise and smooth transmission, maintaining a low-noise state even during long-term operation.
Core Components of ZKKN Premium Electric Chain Hoists
链
- DAT alloy steel chain, carburized and nickel-plated for superior corrosion and wear resistance
- Optimized for high-speed, heavy-duty hoisting operations
- Reliable performance across a wide temperature range: -20°C to 200°C
VFD
- Enables soft motor start, reducing inrush current and mechanical shock to the system
- Dual-speed control: efficient high-speed hoisting and precise low-speed positioning
- Ensures smooth, stable, and safer operation for demanding tasks
变速箱
- Precision gear transmission converts high motor speed to low hoisting speed with boosted torque

Security Protection System of ZKE Premium Electric Chain Hoists
- Motor overheat protection: The motor has a built-in thermal sensor that automatically cuts off power in case of overheating, ensuring safer motor operation.
- Electro-disc brake: A normally closed structure, the spring’s braking pressure is only released when energized via an electromagnetic coil. Even in the event of a sudden power outage, it ensures that the load will not slip freely.
- Micro limit switch: Features small contact spacing and short travel. When the chain electric hoist rises or falls to its limit, the micro limit switch automatically cuts off the power, which can effectively prevent the suspended load from colliding with the machine body.
- Friction clutch: It automatically activates when the load exceeds the rated value, cuts off the power supply, prevents the motor from burning out or the chain from breaking, and protects the overall structure of the machine.
- 带锁扣的钩子： 标准高强度安全舌片可有效防止吊钩滑脱，提高起重稳定性，使高空作业更安全。
