Hand chain hoist structure
Author：  Source： http://www.kitolift.com/jishu/n622.html   Release time：2015-06-29
Hand chain hoist to lift the weight, clockwise drag manual, hand chain wheel to rotate, down counterclockwise hands pulled the chain, brake block and brake separation, ratchet resting under the effect of the detent, five tooth long axis drive heavy chain wheel running in the opposite direction, so as to smooth dropped weights. Hand chain hoist the unidirectional ratchet friction disc brake, under load can automatically brake, the pawl in under the action of the spring and the ratchet wheel are engaged, the brake safety work. It is safe and reliable, convenient maintenance, high mechanical efficiency, bracelet pull small, lighter weight for carrying and beautiful shape smaller sizes, durable, applicable to factories, mines, construction sites, piers, docks, warehouses and other used to install machinery, lifting goods, especially for the open and no power operation, more show its superiority. Use hand chain hoist the main parts of the steel materials manufacturing, chain using 800MPa high strength lifting chain, the material is generally 20M2, medium frequency quenching heat treatment, low wear and corrosion chain; high strength hook, material generally for alloy steel, forging type of hook design to ensure that the slow lifting to prevent overload; in line with European CE safety standards.
