ABSTRACT:
The subject invention is an improved apparatus adapted to facilitate the installation of railroad ties, either by automatic or semi-automatic members. The apparatus incorporating the features of the subject invention comprises, in general, a pair of laterally disposed stabilizing and leveling arms flexibly mounted to each side of a vehicle that is capable of riding on railroad tracks, and wherein each said stabilizing and leveling arm is in turn comprised of two flexible subarms flexibly mounted together in the manner of a parallelogram structure. Mounted at the end of the parallelgram-like subarms are flat brace members. Integrally affixed to the end of such flat brace members are self-levelling jacks. A flexible movable boom member is integrally mounted to a portion of such vehicle, with such boom member having a rotatable holding device rotatably and integrally affixed to the end of the boom arm, such holding device adapted to hold a portion of a tie member. The rotatable holding device can be rotated perpendicular to the railroad track and be used as a shovel for removing ballast. The apparatus incorporates retractable rail wheels so positioned to facilitate the removal and insertion as mounted on the center of the parallelogram-like subarms which are clamping devices that hold the tractor securely on the rail.
