Abstract
A bracket and tension rod device is mounted to a top-drive dolly to carry the weight of a sheave wheel assembly. The device is deployed by connecting the sheave wheel assembly to a rigid dolly arm with an adjustable tension rod to relieve a gooseneck from adverse tensile, compressive and bending forces from the movement of a wireline through the sheave assembly.
