Apparatus for rotating a sucker rod string having a position indicator

An apparatus for rotating a sucker rod string, comprising:

• a housing defining an inner cavity, an upper opening, and a lower opening, the lower opening sized and dimensioned to receive a first portion of the sucker rod string;
• a cap disposed over the upper opening of the housing, the cap defining a rod opening aligned with the lower opening of the housing to receive a second portion of the sucker rod string spaced from the first portion, the cap engageable with the sucker rod string such that rotation of the cap causes rotation of the sucker rod string;
• an actuator arm extending from the housing, the actuator arm moveable between a first position and a second position;
• a driving gear disposed within the inner cavity of the housing, the driving gear mechanically coupled to the actuator arm such that movement of the actuator arm between the first position and the second position causes rotation of the driving gear;
• a driven gear disposed within the inner cavity of the housing, the driven gear in meshing engagement with the driving gear such that rotation of the driving gear causes rotation of the driven gear, the driven gear coupled to the cap such that rotation of the driven gear causes corresponding rotation of the cap;
• and
• a sensor assembly disposed within the inner cavity of the housing, the sensor assembly configured to detect movement of the driven gear and, responsive to determining that the driven gear has ceased movement for a predetermined time period, generate an alarm indicating that the driven gear has ceased rotation.
