Abstract
A movable crawler system that moves a crawler of railroad equipment from a first position to a second position is disclosed. The crawler system includes a crawler and a positioning system that moves the crawler. The positioning system includes a horizontal positioner and may include a vertical positioner, which move the crawler horizontally and vertically, respectively. The crawler system may be used in railroad equipment for rail change-out processes. When used in this manner, the crawler system enables the crawler to be moved between a position on a guard timber and a position on or above the railroad ties. Because the crawler can be moved to a position on the guard timber, when the equipment is operated on a track suspended by a bridge, which has one rail missing, the need for workers to work outside the rails to raise the equipment above the guard timber is eliminated.
