ABSTRACT:
The invention generally relates to apparatus and methods for moving tubulars into and out of a well bore, and particularly, a tubular injector with two or more gripping members which bind the outer surface of the tubular, two or more actuators which cause the gripping members to bind or release the tubular, and at least one reciprocator for translating a gripping member to move the tubular, or for repositioning the gripping member. A method of translating a tubular is also provided which includes the steps of binding the outer surface of a tubular with at least one gripping members by engagement with an actuator, and translating a gripping member by reciprocator to move the tubular.
