The ZKE medium electric chain hoists feature several improvements over the HHBB standard electric chain hoists: a one-piece cast aluminum body for dust and spray protection, and a newly added friction clutch to effectively prevent damage to the body and load chain during overload and lifting. The ZKE medium electric chain hoists can be widely used for lifting heavy objects or installed on single-girder overhead cranes, straight and curved I-beams, and also on double-girder overhead cranes, portable gantry cranes, or cantilever cranes. They are commonly used lifting devices in industrial and mining enterprises, on railways, at docks, and in warehouses.

Product Features of ZKE Medium Electric Chain Hoists
- Low-Headroom Optimized Design: The compressed body structure effectively shortens the distance between the crossbeam track and the machine body, allowing for higher lifting heights and solving the problem of insufficient lifting stroke in low-ceilinged factories.
- Dual Safety Protection: A new friction clutch overload protection system, coupled with upper and lower limit switches, prevents overload and overtravel, offering a safety level higher than the standard model.
- High-Protection and Durable Body: IP55 protection rating + M5 working class, cast aluminum housing for excellent motor heat dissipation, suitable for use in harsh conditions such as humid and dusty environments.
- Stable Dual-Axis Trolley Operation: Utilizing dual drive shafts and dual sets of wheels, it ensures even force distribution, prevents deviation, and resists swaying, resulting in smoother long-distance/heavy-load travel.
- High-Strength Load-Bearing Connection: Forged lifting rings and high-strength bolts ensure reliable bearing of suspended and impact loads, offering convenient assembly and disassembly, and robust durability.
