Abstract
A drill rod spinner device includes a mount, a first base half having a first end and a second end in which the first base half at the first end is rotatably coupled to the mount and a first clamping roller operatively associated with the second end of the first base half. A second base half includes a first end and a second end in which the second base half at the first end is coupled to the mount. A second clamping roller is operatively associated with the second end of the second base half. A rotary actuator assembly is secured to the mount. A flexible belt is operatively associated with the rotary actuator assembly. An idler roller assembly maintains engagement between the flexible belt and the rotary actuator as the first base half is rotated relative to the mount.
