china vital 1 ton chain block
The 1-ton manual chain hoist, VITAL design, is a reliable mechanical lifting device for handling loads in industrial, workshop, and construction environments, operating with a simple mechanism without the need for electricity or hydraulics. This hoist features a durable steel body with anti-rust and wear-resistant coating, ensuring consistent performance against impact and harsh weather conditions. Its internal system consists of heat-treated steel gears with high surface hardness typically in the 50–60 HRC range and a safety factor of 4:1, allowing it to safely handle a rated load of 1000 kg. The automatic brake mechanism, equipped with wear-resistant friction plates, ensures secure load holding at any height and prevents sudden load release. Due to its compact design and lighter weight compared to similar models, this hoist is easy to transport and install in various worksite locations.
The load chain of the 1-ton manual chain hoist, VITAL design, is typically made from alloy manganese steel with a **G80** grade, compliant with **EN 818-7** standards for lifting applications. The chain size is generally **6 mm**, with a nominal tensile strength of approximately **800 MPa**, capable of withstanding both shock loads and long-term use. The chain surface is protected with a bl
