Product Description
HSZ-YTG 20T Low Headroom Trolley Hoist
Product Introduction:
HSZ-YTG 20T Low Headroom Trolley Hoist is a heavy-duty manual lifting solution designed for applications where headroom is severely limited. With a rated capacity of 20 tons, this unit combines a hand chain hoist and a manual trolley into one compact, low-profile assembly, making it ideal for use in shipyards, marine engine rooms, low-ceiling workshops, containers, and underground sites.
Key Features:
1.High Capacity, Low Clearance – Lifts up to 20 tons while requiring minimal vertical space, thanks to its optimized low headroom design.
2.Integrated Trolley – The built-in manual trolley runs smoothly on I-beam rails, allowing lateral movement of heavy loads with ease.
3.Durable Construction – Made from high-strength alloy steel with heat-treated gears and hooks for safety and longevity.
4.Corrosion Resistant – Suitable for marine environments with optional galvanized or painted surface treatment.
5.Easy Operation – Two manually operated hand chains: one for lifting/lowering, the other for trolley travel along the beam.
6.Adjustable Beam Width – The trolley can be adjusted to fit different flange widths of standard I-beams.
7.Safety Guaranteed – Equipped with overload protection, automatic brake system, and double-pawl clutch for secure holding.
