Patent number: 8245648Abstract: A guided vehicle transportation system is described in the application. The system includes guard wheels and a guard rail positioned along a center line of a guide track. The guard rail has a groove in which the guard wheels are received with a predetermined clearance between the periphery of the guard wheels and side walls of the groove. The guard rail has a flange extending toward the groove at the top of each side wall. The vehicle has first arms extending in longitudinal direction and being attached rotatably at a central part of an axle provided for suspending each pair of front wheels and rear wheels, and the guard wheels are attached rotatably and directly to the both end parts of the first arms or attached rotatably to both end parts of second arms each of which is attached to a corresponding end part of the first arms.Type: GrantFiled: October 31, 2007Date of Patent: August 21, 2012Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Shunji Morichika, Katsuaki Morita, Masahiro Yamaguchi, Kosuke Katahira, Yasuhiro Nagamichi
