Abstract

See full text

A rotator mechanism for rotating an elongate member in a pumping system includes a body member having a longitudinal body axis and a through-hole aligned with the body axis and configured to receive the elongate member. The rotator mechanism also includes a worm gear concentric with the body axis and a worm meshing with the worm gear. The rotator mechanism includes a lever configured to rotate the worm, and a clutch coupled between the lever and the worm and configured to cause the worm to rotate in a first direction when the lever moves in the first direction. Rotation of the worm causes the worm gear and the elongate member to rotate about the body axis.
