Before use, check the trough, axle, pulling plate, hook and other parts of the pulley to see whether there are cracks and damages, whether the parts rotate flexibly, whether the screw is loose or not, and unqualified pulleys are not allowed to use. If it is found that the pulley and hook are deformed and cracked or the location of the shaft is not perfect, it can not be used.
