Working principle of manual chain hoist and chain block

To lift good upside, pull the chain clockwise and then sprocket runs, pressing ratchet wheel and brake base as a body to rotate together, long axis rotating teeth gear, short axis and spline hole gear. Thus the lifting sprocket on the spline hole gear will drive the lifting chain to lifting goods stably.

Lifting goods down, anticlockwise pulling the chain, the brake base will separate from the brake pad, ratchet wheel will stop under the influence of ratchet pawl, five long shaft lifting sprocket driven gear in the opposite direction, then lifting goods stably.
The chain block adopts ratchet friction chip one-way brake, can brake under load condition, ratchet pawl mesh with the ratchet wheel under the influence of spring, make the brake work safely.
