Embodiments of the present invention relate to lifting and lowering loads more efficiently and also more economically than known systems. This invention is the continuous movement by mechanical means of a moving crank shaft force point to a desired advantageous position at a desired advantageous moment to achieve improved geometry resulting in a desired low torque factor for a reduced net torque when lifting or lowering an unbalanced load with a beam with a fulcrum and connected to a load and an effort. In one embodiment, a walking beam well pumping unit, the lifting and lowering of the well load can be caused by the reciprocating motion of a beam tipping on a fulcrum and with an effort force point continuously substantially vertically disposed with the moving crank shaft force point. Potentially reduced net torque might allow longer life speed reducers, smaller speed reducers, and longer reciprocating vertical stroke length.

Head with contiguous counterweight dampers on structure
Cushioning dampers are beneficial for preventing stress cracks on a sucker rod reciprocating pump whose circular arc head is contiguous with a counterweight and is pivotably connected to the pitman arm, crank arm weight, and speed reducer. The pitman arm is substantially horizontal and the crank arm to wrist pin phase angle is about 70-90 degrees. Auxiliary counter weight extends from the head weight on a stinger and the head weights are adjustable. The head weight diameter is either constrained within the circular arc head's outer diameter or can be larger. The upper pitman bearings are outboard on the equalizer which is integral with the head. The center bearing of the head is outboard on the rectangular sampson post. The head counterweight increases permissible load on a speed reducer. This invention has embodiments for adjusting sampson post height and pitman arm length; and for changing the stroke length without removing the wrist pin from the crank weight hole.

A movable counterweight that can reduce lifting and lowering torque. In one embodiment, a beam pumping unit can have a movable beam counterweight attached to a positioning drive on the beam and can be intelligently positioned to achieve lowest net torque required by one or more of a prime mover and lowest net gear torque in in the speed reducer. Optionally, positioning can be calculated by one or more of monitoring current requirements of the motor and monitoring the beam load with a load cell, which can then be merged with crank position readings and processed into signals sent to the positioning drive, which causes the counterweight to move to the best position along the on the length of the beam to achieve one or more of near to lowest current draw by the prime mover and lowest net gear torque in in the speed reducer.

A moving counterweight that reduces lifting and lowering torque of an unbalanced load. In one embodiment, a beam pump, an articulated reciprocating counterweight extending above the effort of a class 1 lever on extended pitman arms above the lever effort at the tail bearing to structurally and continuously changes it's position in an air-arc to reduce lifting and lowering torque, by rigid-mechanical geometric re-positioning of the counterbalance effect to and fro, when the rotation is crank arms falling toward the well load, thus mechanically, continuously, favorably, and without friction re-positioning the counterweight either away from the load and fulcrum thereby increasing the counterbalance effect, or nearer to the load and fulcrum thereby decreasing the counterbalance effect, as is desirable to compensate the unbalanced downhole load, where the load in the lift direction exceeds the load in the return direction. The longer the extension of the pitman arm above the beam with the counterweight attached the greater is the counterweight effect of the counterweight deadweight.
