What was the traditional method of powering a cable-tool rig?

Explanation:
Cable-tool rigs power the drill with a heavy hammer action produced by a steam-driven walking beam. A steam engine drives the beam up and down, lifting and dropping the drill string to strike the rock repeatedly. This percussive pounding is what advances the borehole in cable-tool drilling, and the setup could be done with surface steam power without needing electricity or more modern machinery. Electric motors, gas turbines, and hydraulic power came into use later or in different drilling approaches, so they aren’t the traditional means used for this method.
