Abstract:

In the construction of a high-rise building, structural members can be turned by the wind during lifting, making installation work more difficult and reducing productivity. This paper describes a system for the control of rotation around the vertical axis during the lifting of members. The system consists of three major units; a sensing unit, an operation unit, and an actuating unit. The operation unit incorporates a rate gyro, which keeps track of the lifted members in initial direction. It controls the actuating unit, Which consists of a pair of blowers that stabilize orientation during lifting. Although this system contributes greatly to safety and work efficiency when used alone, it will also be an extremely useful sub-system in the future total automation of construction.
