Electrically insulated temporary aerial platform
Abstract
Abstract An electrically insulated aerial platform assembly for use by a lineman on or around utility poles is provided which is constructed to maintain the actual work platform in an electrically insulated condition relative to the utility pole itself and the pole connection hardware associated with the assembly. In preferred forms, the platform assembly includes a work platform presenting an elongated, substantially flat upper work surface where a lineman may by stand, sit or kneel, together with means for temporarily attaching the platform to the utility pole with the platform being electrically insulated from the pole during normal working conditions. Attachment of the platform to the pole is effected by means of an elongated, electrically insulative member secured to the platform and extending toward the pole, with the pole-connection structure coupled to the insulative member at the end thereof remote from the platform. The insulative member is of a length and is formed of an appropriate insulative material presenting a smooth outer surface for resisting accumulation of dirt or other contaminants thereon to maintain the electrical integrity of the overall assembly. Moreover, the insulative member preferably presents a downwardly sloping upper surface in order to dissuade the lineman from directly contacting and supporting himself on the member.
