Abstract: A rocker wheel jack is arranged on a compact frame so that the driving mechanism is placed below the rocker wheel. The mechanism is adjustable so as to vary the spacing between it and a drive wheel. The rocker wheel is adjustably spaced from the drive wheel. A pitman connects the drive wheel and the rocker wheel. The pitman connections to the wheels are further adjustable radially to the wheels. Thus a jack is provided with a possibility of multiplicity of adjustments and a minimum of vertical space and of weight for the jack. The complete unit is readily movable. The driving mechanism is readily accessible for repair or replacement. An oil level sensor is provided in the well with connections transmitting its output to the R.P.M. of the jack.
