  • Patent number: 9145648
    Abstract: A pulling tool includes a housing and a tube disposed within the housing, the tube configured to supply hydraulic fluid. The spike puller further includes a piston rod connected to a piston. The piston rod has a hollow axial bore, and the piston and the piston rod are axially moveable relative to the tube. The spike puller has a passage communicating fluid from the tube to the piston. The passage is contained within the housing. The passage is variable between a first configuration in which hydraulic fluid flows at a first restricted flow so as to provide a slower retraction of the piston rod and a second configuration in which hydraulic fluid flows at a second less restricted flow so as to provide a faster retraction of the piston rod.

  • Publication number: 20060178097
    Abstract: A portable rail cutting apparatus is presented herein. The portable rail cutting apparatus comprises a housing encasing a motor, the motor configured to drive a rotary abrasive blade, a drive pulley coupled to the motor, a driven pulley coupled to the rotary abrasive blade, a loop drive belt engaged by the drive pulley at one end and engaging the driven pulley at another end, and an automatic belt tensioning mechanism. The automatic belt tensioning system comprises a spring and push rod assembly that applies a pre-set tension to the loop drive belt. The portable rail cutting apparatus may also comprise an adjustable protective guard member that partially surrounds the rotary abrasive blade and includes a detent mechanism configured to provide integral travel positions for the adjustable protective guard member.
