Abstract
A long-stroke pumping unit can be moved away from and toward the wellhead by using a single hydraulic power source via a control interface that is coupled to the hydraulic power source and configured to control both the vertical movement and the horizontal movement of the long-stroke pumping unit. The control interface can control the hydraulic power source for extension and retraction of a hydraulic cylinder for horizontal movement of the unit, and the same control interface can control the same hydraulic power source for extension and retraction of a first vertical hydraulic jack and a second vertical hydraulic jack of the long-stroke pumping unit for vertical movement of an end of the long-stroke pumping unit.
