The diverter pulley guides the rope precisely and allows it to operate with ease. The winch pulley block which doubles the pulling force of a winch, deflects the force and distributes it so that it easily adapts to on-site working conditions. The movable covers of the deflection roller, which are mounted on a movable wiper, will be moved aside and turned sideways, so that you can insert the rope into the pulley. When the rope is inserted, the two covers must be brought together again so that the two eyelets overlap. The eyelet must be secured with a strap or buckle made of textile material. Metal hooks or loops should not be used to secure the pulley. Furthermore, the spool bearing must be lubricated before first use.
