In the process of lifting the heavy object, the 500kg Chain Block is to drag the manual chain clockwise and the hand wheel to rotate, and when descending, the chain is pulled counterclockwise, the brake seat is separated from the brake pad, and the ratchet is in the Under the action of the pawl, the long axis of the five teeth drives the lifting sprocket to run in the opposite direction, thereby smoothly descending the weight.
In actual operation, the 500kg Chain Block can brake by itself, with safety and reliability, easy maintenance, high mechanical efficiency, small pull of the bracelet, light weight, easy to carry, beautiful appearance, small size and durability. Therefore, it is widely used in factories, mines, construction sites, docks, docks, warehouses, etc. to install machines and lift goods, especially for open-air and power-free operations, and shows its superiority.
The main structural components of the 500kg Chain Block are made of high-quality alloy materials. The chain belongs to the high-strength lifting chain and is subjected to medium-frequency quenching heat treatment, low wear and anti-corrosion treatment. It is also equipped with high-strength hooks, made of alloy steel, and the calender-type hook design ensures a slow lift to prevent overload.
