The present invention provides an improved cross arm structure which supports various elements such as pin insulators and keeps the supported elements from crushing the arm when connectors and pins are tightened. According to a preferred embodiment, the present invention includes a cross arm with an inserted geometric structure which extends between the outer walls of the cross arm structure.

Cross arm support structure

An improved composite crossarm for utility poles is disclosed having an outer casing of resin impregnated fiberglass with first and second load walls which are joined together by laterally spaced apart opposite sidewalls. Each sidewall is generally parallel to the other and is provided with an aperture. A load bearing member or bolt extends between the first and second load walls and has opposite ends which extend through the outer casing for coupling to an attachment member for securing a load to the composite crossarm. At least one end of the load bearing member has a wall engagement portion which seats against the exterior surface of the first load wall. A cylindrical sleeve is located within the interior of the outer casing between the first and second load walls and has a length substantially equal to the distance between the first and second load walls. This allows the load transfer body to abut against the interior surfaces of the first and second load walls when force is exerted on the attachment member. A cross member is closely received within the apertures of the sidewall and is fixed to the load transfer body. This causes force to be transferred to the sidewalls from the load transfer body.
