Abstract
A self-aligning articulated crossarm assembly for supporting electrical transmission lines is provided which utilizes unique mounting structure for insuring that the assembly assumes a true perpendicular orientation with respect to the supported line even in the event that the mounting holes therefor in the pole are off-center or otherwise out of alignment. Ball and socket mounting of the horizontal support arms of the assembly in conjunction with multi-clevis coupling of the strain member thereof between the horizontal arms and pole permits use of the assembly on irregular poles or the like without the necessity of precisely boring the mounting holes for the assembly. In preferred forms, the ball sockets for the support arms have open bottoms so that upon failure of the strain member the arms can swing downwardly while remaining operatively secured to the pole with the line still supported above-grade.
