WIPO Patent Application WO/2019/102743
Kind Code:
A1
Abstract:
Provided is a traveling dolly (5) capable of traveling along both a plurality of first tracks (31) arranged along a first direction and a plurality of second tracks (32) arranged along a second direction perpendicular to the first direction, wherein the dolly is provided with a travel unit and a drive unit. The travel unit has at least four driving wheels and during any of the travels along the first tracks (31) and along the second tracks (32), the four driving wheels are in parallel orientation and make contact with the first tracks (31) or the second tracks (32). The drive unit rotates each of the four driving wheels about a vertical axis of rotation and thereby causes to intersect, with the tangent line to the clearance circle of a spin turn, a wheel centerline passing through the center of each of the four driving wheels in the plan view, and then rotates each of the four driving wheels about the wheel centerline, thereby performing the spin turn.
