Abstract
A portable railroad spike remover comprises a claw assembly extractor that is shaped to engage and secure a railroad spike previously installed into a rail tie. The claw assembly extractor may include a pair of jaw members that are pivotally connected to each other by a pivoting pin and a rotating pin. Each jaw member may include a lower end configured to contact and secure a railroad spike and a pair of upper members interlocked with each other and pivotally connected to the clevis fastener with the rotating pin. When the drive shaft is rotated, the claw assembly extractor and the mounting flange may move inside the main housing in a vertical direction to extract the railroad spike from the rail tie.
