| description | An oil well pumping unit. The pumping unit has a vertical support column residing adjacent a horizontal support base at a generally transverse orientation. The pumping unit has a standing sheave fixed proximate an upper end of the vertical support column, a carrier bar configured to be attached to a polished rod along the front face of the vertical support column, and a traveling sheave configured to move up and down along the vertical support column. A near-vertical actuator resides along the horizontal support base, and is connected to the traveling sheave. Cyclical movement of the linear actuator causes the traveling sheave to reciprocate up and down along the vertical support column such that upward movement of the traveling sheave produces a downstroke of the polished rod, while downward movement of the traveling sheave produces an upstroke of the polished rod. The linear actuator remains in tension at all times during movement of the polished rod. |
