  • Portable walking beam pump jack
    Patent number: 4788873
    Abstract: A portable walking beam pump jack for use in pumping liquids from an oil well having an elongated frame and an axle with wheels thereon mounted transversely on the frame for providing rolling transportation. Stabilizer pads are provided for securing the frame with respect to a ground location, after transportation. An engine is mounted on the frame and rotates a counterweighted pair of arms which are journalled for rotation adjacent to the frame and parallel to the longitudinal axis of the frame. A drive yoke is connected between the counterweighted arms and a walking beam such that rotation of the arms drives the walking beam in a rocking motion. A foldable support assembly is mounted upon the frame and supports the walking beam. The walking beam can be connected to a sucker rod for pumping from a well.
