In power plant construction site,we must transport the module into a narrow opening of frame structures assembled in multiple stages of multiple pillars and beams. At present, transferring a module from high location you will rotate the module by the rope attached to the module not to contact with the obstacle of the lower. But the work in high location is very dangerous. In this study, we have developed the module rotation control device that can rotate the module while cancel the reaction forces and twist of the rope, by the effect of gyro actuator. By using this device, it is possible to reduce the workers in high location, improve the safety of power plant construction site.
