This paper deals with a research on vibration control for suspended load of crane utilizing a variable-pitch propeller thrust. Vibration suppression of crane load suspended by hoisting rope is an important issue to speed-up crane operation. In this study, a novel vibration control system using a variable-pitch propeller thrust as an actuator is presented. An experimental system using a simple pendulum composed of a load suspended by four thin strings and a variable-pitch propeller with a motor. The propeller thrust decelerates the oscillation of the pendulum. The basic property of the system is investigated experimentally and is its effectiveness is confirmed.
