Rail spike remover
A portable railroad spike remover comprises an extractor that is shaped to engage and secure a railroad spike previously installed into a rail tie. A drive shaft is connected to the extractor such that as the drive shaft is rotated, the extractor is vertically raised and lowered within a main column. The extractor may have an opening extending through at least one side to engage the railroad spike.
