RAILROAD SPIKE REMOVER
A method of removing a railroad spike (10) from a rail tie (12) comprises positioning a railroad spike remover (100) with a main column (102) and an extractor near a railroad spike (10), sliding a top of the railroad spike into an opening (147, 247) of an extractor (140, 240) of the railroad spike remover, and rotating a drive shaft (120) of the railroad spike remover with a rotating tool to raise the extractor in a vertical direction inside the main column (102) to extract the railroad spike from the rail tie. The main column has a first end (104) and a second end (106), the first end having a bearing housing (110) connected to the main column and containing a bearing (114), wherein the drive shaft extends through the bearing and the bearing housing.
