A rope, cable, belt, or chain usually runs over the wheel and inside the groove, if present. Pulleys are used to change the direction of an applied force, transmit rotational motion, or realize a mechanical advantage in either a linear or rotational system of motion. Designed for use with rope or cord in indoor and outdoor applications, but only pulley here, rope is not included.
