DHK Electric Chain Hoist 1T–10T 380V

DHK Electric Chain Hoist Description

DHK Electric Chain Hoist is a specialized, heavy-duty material handling engine engineered for large-span collaborative hoisting and high-load industrial applications. Designed around a 380V/50Hz industrial electrical standard, this robust heavy duty electric hoist combines precision motor ratings (0.5 kW to 1.1 kW) with controlled lifting speeds (1 m/min to 3 m/min), balancing exceptional load stability with operational safety.

As a certified China hoist supplier, we manufacture the DHK series across rated lifting capacities from 1 Ton to 10 Ton (with experimental test loads up to 12.5 Ton). Featuring an innovative double sprocket drive mechanism and a thickened protective steel casing, this series serves as an essential lifting system for high-rise climbing formwork, storage tank erection, bridge segment positioning, and heavy plant assembly.

Core Advantages & Product Features

• Double Sprocket Drive System: Features a dual sprocket guidance structure that prevents chain reversal, reduces chain binding, and ensures ultra-smooth chain travel during heavy lifts.

• Thickened Protective Casing: Heavy-duty outer metal housing provides high structural rigidity, protecting internal drive gearing against job-site collisions and severe weather.

• Manganese Steel Anti-Detachment Hook: Drop-forged manganese steel safety hooks rotate 360 degrees without cracking, equipped with spring latches to prevent accidental sling slippage.

• Sensitive Industrial Remote Control: High-response pendant controller allows precise micro-positioning and rapid emergency stop execution for elevated safety margins.

• High Synchronization Accuracy: Controlled low-speed hoisting mechanics ensure smooth, shake-free vertical travel when multiple units are linked for synchronized group lifting.

Frequently Asked Questions

Q1: What are the specific benefits of the double sprocket design in the DHK hoist?

A: The double sprocket system provides dual-point engagement with the load chain, which prevents chain twist, drastically reduces chain wear, and guarantees smoother vertical motion under heavy loads.

Q2: Can the DHK series be used for synchronized group lifting of large storage tanks?

A: Yes. The DHK series is specifically engineered with uniform lifting speeds and high stability, making it ideal for multi-point synchronized tank jacking and climbing scaffolding operations.

Q3: Are custom lifting heights above 12 meters available?

A: Yes. We offer fully customized Grade 80 alloy load chains and high-capacity chain containers to support vertical lifting heights up to 30 meters or more for specialized construction projects.
