摘要： Electrical switchboard apparatus includes a switchboard having a plurality of cells adapted to receive circuit interrupters and related electrical equipment, a weatherproof housing enclosing the switchboard and providing a maintenance area between the front of the switchboard face and the interior front wall of the enclosure, and a traveling lifting mechanism movably supported at the top of the maintenance area upon two parallel rails extending across the switchboard face and the interior front wall of the enclosure. The lifting mechanism is a bridge-type crane comprising a perimeter frame of U-shaped steel channel members and a flanged steel plate bolted thereto. The lifting mechanism also includes a winch and a pulley supporting a lifting cable attached to the winch. The pulley is supported upon a steel pin removably inserted into any of a series of holes in angled support members mounted within the perimeter frame. The movable pulley provides lifting points at various distances from the face of the switchboard to accommodate a variety of breakers sizes. The lifting mechanism presents a low profile allowing it to be completely enclosed by the housing while still enabling the entire apparatus to be transported on standard flatbed trucks.
