The operation method of lifting heavy objects upward with a hand chain hoist is:
First, pull the hand chain hoist clockwise. ． Hand pull chain:． ． .Thereby driving the hand sprocket transmission, pressing the friction plate ratchet and the brake seat into one body to rotate together, and the long tooth axis rotates the plate gear, the short tooth axis and the spline hole gear. Through these lifting sprockets installed on the spline hole gear, the lifting chain is driven, so that the heavy object can be lifted smoothly.
Secondly, the principle of the hand chain hoist when lowering heavy objects is basically similar to that of lifting heavy objects. When lowering heavy objects, the hand chain is pulled counterclockwise, and the brake pads are separated by the brake seat. The ratchet plays the role of the pawl. When the machine is at rest, the five-foot long axis drives the lifting sprocket to run in the reverse direction, thereby achieving a smooth lowering of the heavy object. This is the operating principle of the hand chain hoist.
Of course, hand chain hoists generally use ratchet friction plate single-phase brakes, which can automatically brake under load. The pawl engages with the ratchet under the action of the spring, so that the brake starts to work safely.
