ABSTRACT:
A portable apparatus for reinstalling loosened railroad spikes. The apparatus includes a wheel-mounted chassis adapted for rolling along railroad rails and having a crawler attached thereto having a lowered, operating position and a raised position. The crawler includes a carriage with a plurality of crawler wheels thereon interconnected by a plurality of link-belts. The belts engage loosened spikes as the apparatus rolls along the rails when said carriage is in the operating position. The link-belts have a plurality of spike head engaging indentations defined along an outer surface thereof. In the preferred embodiment, at least one of said link-belts further engages a crawler drive wheel portion of a drive wheel mounted on the chassis. The drive wheel may be rotated by a hydraulic motor. The carriage may be alternately raised and lowered by a hydraulic cylinder actuated by fluid pumped thereinto from a pump through a two-way hydraulic fluid valve.
