Abstract
An improved gripper unit for use in an injector for handling coil tubing, pipe, rod, cable, or similar elongate objects, this gripper unit being provided with gripping surfaces which contact the coil tubing in V-block fashion and thus will grip such tubing of differing diameters. This gripper unit will enable the injector to support a given load while applying less squeeze. In the case of handling coil tubing or pipe, the stresses induced by these improved gripper blocks are very considerably reduced as compared with conventional gripper blocks.
