Product Description
3T Electric Trolley Type Chain Hoist (Treble Chain)
Product Introduction:
Our Electric Trolley Type Chain Hoist (Treble Chain) is designed for heavy-duty lifting in industrial and marine environments, including ship hatch cover handling, workshop crane systems, and offshore applications.
Featuring a three-chain lifting mechanism, this hoist provides higher load capacity and improved safety compared to single or double chain models. The electric trolley allows smooth horizontal movement along an I-beam or overhead rail, while the electric chain hoist handles vertical lifting with precision and control.
Key Advantages:
*Treble chain design – Distributes load evenly across three chains, enabling stable lifting of 10–30 tons.
*Electric trolley travel – Reduces manual effort, improves positioning accuracy.
*Compact & robust – Suitable for low-headroom installations.
*Fail-safe brake – Ensures secure load holding.
*Marine-grade options – Corrosion-resistant coatings available for shipyard use.
