Abstract
In the transportation work of construction materials at high-raise building, the hung load such large steel beam and pre-cast concrete panels are frequently rotated by the wind pressure and by the inertia power accompanied with movement of crane. For the purpose of suppressing the load rotation, a high power control device installed with gyroscope was developed to improve the past developed device greatly. The main improvement points are as follows, the design of gyroscopic mechanism to generate high power moment, the body design fed bake the wind analysis, the development of energy conservation circuit of gyroscopic motor and inverter, the introduce of operation system that considered safety and smartness. As result of these improvements and developments, the construction materials could be kept initial position against outer disturbance using the inverse moments passively and the loads were turned at the desired angle of setting position collectedly controlling the moment activity. Moreover, the successive operating time was progressed very long in spite of only a battery charge. Applying this device to transportation works, the effective and smooth operations lifting and setting of the materials are performed at a construction site.
