Abstract
Provided is an overhead conveyor that conveys a carrier loaded with a workpiece. The carrier includes a primary carrier, and a secondary carrier having a hanger that supports the workpiece. The overhead conveyor includes a rotation drive device that rotates the secondary carrier around the vertical axis, a friction brake device that makes the secondary carrier non-rotatable with respect to the primary carrier, and a rotation positioning device that is disposed on a ground side, and positions the secondary carrier at a predetermined rotation end position. The friction brake device, in an operating state thereof, brings a friction member included in a main body provided in the primary carrier, into press-contact with a brake member provided in the secondary carrier.
