Abstract (en)
[origin: EP3677725A1] A portable railroad spike remover (500) comprises a housing (502), a drive shaft and a claw assembly extractor (540) that is shaped to engage and secure a railroad spike previously installed into a rail tie. The claw assembly extractor (540) includes a pair of jaw members that are pivotally connected to each other by a pivoting pin and a rotating pin, wherein the claw assembly extractor (540) is connected to a mounting flange. 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 a clevis fastener connected with the rotating pin. When the drive shaft is rotated, the claw assembly extractor (540) and the mounting flange may move inside the main housing (502) in a vertical direction to extract the railroad spike from the rail tie.
