ABSTRACT:
An attachment for a tool used to attach and remove load break elbows and protective caps from bushings disposed on a transformer is provided. The tool attachment includes an elbow engaging member that is positionable around a load break elbow or cap fixed to a bushing. The engagement member is fixedly secured to a horizontal bar that includes a number of aligned openings extending through the bar. These openings are selectively alignable with a pair of openings disposed on a vertical bar to pivotally attach the vertical and horizontal bars to one another. The vertical bar also includes an opening through which a pulling eye on the elbow or cap can extend when the tool attachment is positioned on the elbow or cap. A conventional pulling tool can be attached to the eye as it extends through the vertical bar and utilized in conjunction with a pulling rope secured to the vertical bar opposite the pivoting connection in order to quickly and easily remove the elbow or attach the elbow to a bushing without causing extended arcing.
