Abstract

A gripper block for use in grippingly engaging coil tubing, pipe, rod, cable, or like objects having various outside dimensions for ultimately applying a longitudinal load thereto. The subject gripper block has an attachment point preferably at or near the center of the block body to enable attachment to at least one endless chain of an injector apparatus. The gripper block further has a pair of gripper surfaces formed thereon, these gripper surfaces are generally planar and tilted away from each other so as to diverge away from the tubing to be gripped at approximately 90 degrees. The gripper surfaces thus preferably provide a V-shaped engagement configuration which is quite effective in gripping objects of differing outside dimensions with no or minimal scarring of such objects.
