Abstract
A linear motor truck apparatus including: a truck having pairs of wheels rotatably mounted thereon; a supporting mechanism, having a rail extending along a line of travel of the truck, for supporting and guiding the truck along the line of travel by engaging the wheels with the rail; and a drive mechanism, including the linear motor, for driving the truck so that the truck may travel along the line of travel. The rail includes a pair of elongated sub-rail members each having a pair of inclined engaging faces parallel to the line of travel and converging to each other so that each sub-rail member has substantially V-shaped cross section and a jointing mechanism for jointing the sub-rail members so that the engaging faces of each sub-rail member converge to opposite directions; the wheels are mounted in at least four pairs; and the truck includes a mounting mechanism for mounting the at least four pairs of wheels thereto so that two pairs of the wheels are disposed to engage with one pair of the engaging faces and the other pairs are disposed to engage with the other pair of the engaging faces.
