摘要： A drill pipe spinner is set forth. It is suspended under a hanger and has upper and lower mounting plates. An air motor with cooperative gear box is supported on the upper mounting plate and extends a rotatable shaft through the mounting plate to rotate a driven sprocket. Through the use of suitable sprockets, symmetrically located left and right rollers arc rotated. In addition, the device incorporates an air cylinder which has an extending piston rod which connects by means of a bell crank which clamps the drill pipe.
