The 3-ton manual chain hoist, Chinese VITAL design, is engineered for the safe handling of heavy loads in industrial sites, workshops, and construction projects. The unit features an alloy steel body with an anti-rust and wear-resistant coating, ensuring long service life. Its power transmission system includes heat-treated steel gears with a surface hardness of approximately 55–60 HRC and lubricated bearings to reduce friction. The hoist has a rated capacity of 3000 kg and a standard lifting height of 3 meters, making it suitable for various applications. The net weight is approximately 28–32 kg, which, despite the high capacity, allows for relatively easy transport and installation.
The load chain of this hoist is made from manganese alloy steel, grade G80, and meets EN 818-7 standards for heavy lifting applications. The chain size is typically 10 mm, with a tensile strength of around 800 MPa, capable of handling both dynamic and static loads. The chain surface is treated with black phosphate or galvanized coating for enhanced corrosion resistance. The hoist usually has a safety factor of 4:1, which in static tests means withstanding at least 12,000 kg before failure. These features make this model a reliable choice for industrial and heavy-duty operations.
