Structure and disassembly of chain hoists
The working principle of the chain hoist: As an upgraded version of the fixed pulley, the chain hoist fully inherits the advantages of the fixed pulley. At the same time, it adopts a combination of a reverse reverse reverse brake reducer and a chain pulley group, symmetrically arranging a two-stage spur gear rotation structure, which is simple, durable, and efficient.
Hand chain hoist power system: The hand chain hoist rotates by pulling the manual chain and hand chain wheel, pressing the friction plate ratchet and brake seat into one and rotating together. The tooth length shaft then rotates the plate gear, tooth short shaft, and spline hole gear. In this way, the lifting sprocket installed on the spline hole gear drives the lifting chain, thereby smoothly lifting the heavy object. Adopting a ratchet friction plate type one-way brake, it can self brake under load, and the pawl meshes with the ratchet under the action of the spring, ensuring safe operation of the brake.
The operation process of a chain hoist: When lifting a heavy object, pull the manual chain and chain wheel clockwise to rotate, and when lowering, pull the manual zipper strip counterclockwise to separate the brake seat from the brake pad. The ratchet is stationary under the action of the pawl, and the five tooth long shaft drives the lifting sprocket to run in the opposite direction, thereby smoothly lowering the heavy object. Hand chain hoists generally use a ratchet friction plate type one-way brake, which can brake on its own under load. The pawl meshes with the ratchet under the action of the spring, ensuring safe operation of the brake.
