20t Electric Trolley Type Chain Hoist
Product Description
20t Electric Trolley Type Chain Hoist
Product Introduction:
Our 20t Electric Trolley Type Chain Hoist is an ultra-heavy-duty, fully motorized lifting solution engineered for the most extreme industrial and marine applications. Capable of handling 20-ton loads with both electric lifting and electric horizontal travel, this hoist delivers maximum power, precision, and safety where manual operation is impossible.
Key Features:
1.Massive Capacity – Rated at 20 tons, designed for the heaviest loads in shipbuilding, steel mills, heavy machinery manufacturing, and large-scale construction.
2.Powerful Electric Trolley – Heavy-duty motorized travel along I-beams or overhead rails provides smooth, controlled horizontal movement without any manual effort.
3.Robust Multi-Chain System – Utilizes five or six load-bearing chains to evenly distribute the extreme 20-ton load, ensuring safety, stability, and extended component life.
4.Dual-Speed Lifting – Two-speed lifting operation allows for slow, precise positioning of heavy loads as well as faster travel when needed.
5.Heavy-Duty Braking System – Dual fail-safe electromagnetic brakes provide secure load holding even under maximum capacity or power failure conditions.
6.Overload Protection – Electronic load limiter prevents operation beyond rated capacity, protecting both operator and equipment.
7.Industrial-Grade Construction – Reinforced steel housing with weather-resistant and corrosion-proof coating options for marine, outdoor, and harsh environment use.
