Safety, reliability and work requirements of triple chain block

- Feb 23, 2019-

In the process of using the triple chain block, the combination of the reverse brake and the chain pulley block are used, and the two-stage spur gear rotating structure is symmetrically arranged, which is simple, durable and efficient. The triangular hand chain hoist rotates the manual ratchet and the hand wheel, and the friction plate ratchet and the brake seat are pressed together to rotate together, and the long shaft of the tooth rotates the plate gear, the short shaft of the tooth and the spline hole gear.

The hoisting sprocket on the spline hole gear of the triple chain block device drives the hoisting chain to smoothly lift the weight. The ratchet friction plate type one-way brake can brake itself under load, and the pawl meshes with the ratchet under the action of the spring, and the brake works safely.

The triple chain block is safe, reliable, easy to maintain, high in mechanical efficiency, small in pulling force of the bracelet, light in weight, easy to carry, beautiful in appearance, small in size and durable. It is suitable for factories, mines, construction sites, docks, docks, warehouses. It is used to install machines and lift cargo, especially for open air and powerless operation.
