How To Get A Railroad Wheel Off An Axle

Union Pacific Railroad in Pocatello, Idaho wondered the same thing. With a little help from their maintenance department we designed a hydraulic system that would provide 300 tons of pulling force required to free from the axle a railroad wheel. Wheels and axles were rolled down a track and positioned next to the wheel puller. The hydraulic system then would extend out and behind the wheel, then down to firmly grasp the back of the wheel. Then with a maximum pulling force of 300 tons would pull the wheel free from the axle. The wheel would remain on the axle and rolled down the track to the next station for removal of the wheel, and the next wheel assembly would roll in.
