It is suitable for the short distance lifting of small equipment and goods, the lifting capacity is generally not more than 10t, the maximum can reach 20t, and the lifting height is generally not more than 6m. The shell material of chain block is high-quality alloy steel, which is firm and wear-resistant, with high safety performance. When the chain block lifts the heavy object upward, it pulls the manual chain and chain wheel clockwise to rotate. When it descends, it pulls the hand zipper bar anticlockwise. The brake seat is separated from the brake pad, the ratchet wheel is stationary under the action of the pawl, and the five tooth long shaft drives the lifting chain wheel to run in the opposite direction, so as to smoothly lower the heavy object. Generally, ratchet friction disc one-way brake is used in chain hoist, which can brake automatically under load, and the pawl is meshed with ratchet under the action of spring, so that the brake can work safely.
It is safe and reliable, easy to maintain, high mechanical efficiency, small chain tension, light weight, easy to carry, beautiful appearance, small size, and durable. It is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. to install machines and lift goods, especially for open-air and non power operation.
The main parts of the chain block are made of alloy steel. The chain adopts 800MPa high-strength lifting chain, which is generally made of 20m2, medium frequency quenching heat treatment, low wear and anti-corrosion chain. The high-strength hook is made of alloy steel, and the forging hook design ensures the slow lifting to prevent overload. It meets the European CE safety standard.
