Hand chain hoist is to start by pulling the chain drive to start the sprocket rotation will be friction plate, ratchet, brake seat, pressed into one, driven by the 5-tooth long axis rotation, 5-tooth long axis of the piece gear meshing, the short axis of the sprocket with four teeth pressure into one of four teeth short axis with the splined hole gear meshing, spline hole gear and lifting sprocket spline driven lifting chain, chain hoists talent upgrade heavy objects.
Hand chain hoist drive gear with a symmetrical arrangement of two sets of two spur gear transmission, composed of two parallel transmission chain by the parallel intermediate gear in the between bracelet axle lifting chain, axle, while the beautiful appearance but structure compact, the bracelet wheel mounted crane chain axle center, and thus the work and working-class gear have the same center of the interval.
Due to the structural characteristics of the chain hoists in the manufacturing process should be to ensure that the relative position of the correctness of the gear and assembled to make the work any hour of gears and gear between the occlusal compact.
