Abstract
A slewing apparatus includes a control section that performs at least a slewing angular velocity pattern determination process. In the slewing angular velocity pattern determination process, the slewing angular velocity pattern is determined such that in a first interval and a second interval of a control time T that is shorter than a cycle determined by a pendulum length of a suspended load that is in a pendulum motion, a difference between a maximum angular velocity and a minimum angular velocity increases as the control time T decreases.
