Abstract
There is provided a conveyance device that can convey a conveyance truck composed of two truck bodies on which a worker rides and does a work in a widthwise direction of a large conveyance object, using a friction type drive unit disposed on a linear route or a curved route, which can improve workability and reduce manufacturing cost. A conveyance device includes a connecting device C for connecting conveyance truckson front and rear positions. Each of the trucksis configured so that a first truck bodyA whose front and rear end surfaces are arc-shaped projections in plan view and a second truck bodyB whose front and rear end surfaces are arc-shaped recesses in plan view are connected to be capable of curving in a horizontal direction, and upper surfaces of the first truck bodyA and the second truck bodyB are approximately horizontal surfaces. Portions of the second truck bodyB that are radially inside a curved route and forms the arc-shaped recesses are composed of oscillation pieceas mobile bodies that make side surfaces of the first truck bodyA and the second truck bodyB approximately linear on a linear route and touch the side surface of the first truck bodyA to move on the curved route.
