Abstract
A technique of a heavy object turning apparatus that is compact, is enabled to reduce the distance between the center of gravity of a heavy object and a pivot positioned on an axis, and is configured so that a turning arm and a drive unit has a length in the direction of an axis passing through the pivot around which the heavy object is turned. A control unit fixes a support base onto a stand. An orthogonal axis reduction gear serves as an anterior reduction gear and has a configuration in which an output shaft is on an axis of a planetary gear type reduction gear serving as the posterior reduction gear. An input shaft is perpendicular to the axis. The orthogonal reduction gear is constituted by a hypoid reduction gear or a worm-geared reduction gear. A motor is disposed on the bottom surface of the orthogonal reduction gear.
