摘要： A crossarm system adapted to support power lines from a vertical pole. The crossarm system comprises a wooden crossarm member and first and second nail end plates. The wooden crossarm member defines upper, lower, inner, and outer surfaces and first and second end surfaces, a main bore, a plurality of pin bores, and at least one brace bore. Each nail end plate comprises a plate member defining an inner surface and an outer surface and a plurality of nail projections extending from the inner surface of the plate member. Each nail projection defines a width dimension. In use, the first and second nail end plates are displaced towards the first and second end surfaces, respectively, such that the nail projections enter the wooden crossarm member. The nail projections are arranged such that the width dimensions substantially prevent splitting of the ends of the crossarm member.

摘要： A cooling tower is formed from fiberglass reinforced polyester resin structural components including a basin, vertically extending columns, vertical side panels, and a cover. The fill material for heat/mass exchange is supported directly by the basin to eliminate the weight of a separate support system and to reduce the load on the columns and panels. A fan is mounted on the cover, and the weight of the fan is supported by the cover and the columns. The panels do not have to support the weight of the cover and the fan, and the panels can be formed of relatively thin, lightweight material. The columns do not have to support the weight of the fill material and can also be relatively lightweight.
