More Information
Summary:A machine for driving spikes into the ties of a railroad track includes a spike driving assembly movably disposed relative to a frame for gripping spikes and driving gripped spikes into the ties, the spike driving assembly having a spike pushing function and a spike percussive function. In the pushing function the spike driving assembly pushes the spike a specified distance into the tie by the application of constant pressure, and in the percussive function the driving assembly percussively completes the driving of the spike into the tie. An operator may selectively alternate between the pushing and percussive functions.
