Abstract

The present invention relates to a cross rail structure for an OHT system and an OHT system using the same. According to the present invention, there is provided a cross rail structure for an OHT system, that is a point at which two orthogonal rails among rails that are installed in an OHT system and transport vehicles intersect with each other. The cross rail structure includes a pair of auxiliary rails that are installed at substantially the same height as the rail at the point at which the rails intersect with each other, and disposed parallel to each other at a predetermined distance; a movement unit that moves the auxiliary rails up and down; a rotation unit that rotates the auxiliary rail so that the auxiliary rails are disposed in any one of two directions orthogonal to each other; and a distance holding unit that holds a distance between the pair of auxiliary rails without an interference with the vehicle.
