On the lifting industry chain hoists

manual hoist is a simple to use, easy to carry the manual lifting, also known as "chain hoist" or "down chain." Chain hoists for small equipment and cargo lifting a short distance, the weight is generally not more than 10t. Chain hoists with a compact, hand-pull small features.
Chain hoists lifting gear structural principle: with reverse backstop brake reducer and chain pulley combination.
Chain hoists hands by pulling the chain, bracelet wheel rotation, the friction plate ratchet, brake pressure into one common rotation axis will rotate five tooth sprocket, four minor tooth gear and spline hole. Thus, the device is splined sprocket holes on the lifting gear driven lifting chains, heavy lifting so smoothly. chain Block  with one-way ratchet friction disc brakes, the braking load on their own, under the action of the spring pawl and ratchet engagement to ensure the safety brake. Chain hoists with safe, reliable, easy maintenance, high mechanical efficiency, bracelets pull small, light weight and portability, smaller size and beautiful appearance, durable, suitable for factories, mines, construction sites, wharves, docks, warehouses, etc. for installation of equipment, lifting goods, especially for open and no power supply, as well as flammable and explosive places more of its important role.
Major parts chain hoists used steel materials,lift hoist chain lifting chain with 800Mpa high strength, high strength material foot hook, chain heat, low wear, corrosion of the chain; calcined playing style hook design ensures a slow start l prevent overload; meet European CE safety standards.
