Hoist equipment and manual hoist chain hoists collectively, mainly because they are informed manpower to complete the installation of the heavy lifting. They have many different structures.
Chain hoists chain by trolling hands, 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, Wire rope hoist so smoothly. Using 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. It is 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 and warehouses for installing equipment, lifting goods, especially for open and no power supply, as well as flammable and explosive places more of its important role.
Lever hoist lever handle by human leverage obtained through match the load line traction, rotation acts on the load of a movement within the clamp body to drive the load operation. Jun Wei lifting lever hoist with a compact, light weight, small size, easy to carry, safe, reliable, long life, pulling force is small, the advantages of small abrasion on the rope. It can be enhanced traction, down, calibration and other operations. If you configure a special device, not only can be used for non-linear traction work, but you can easily select the appropriate operating position, or with a smaller tonnage machines exponentially expand its load capacity, the load can be used for larger tonnage of several machines in parallel operations.
