• Abstract:
  High mast luminaire lowering devices were installed on two projects in Oregon following approval by the Department of Transportation, Federal Highway Administration, of the installations as experimental features projects. Holophane Company, Inc., supplied 23 unites that were installed on the Seventh Avenue - Willamette River Section of I-105 near Eugene in 1973. Valmont Industries, Inc., furnished 38 units that were installed on the South Tigard Interchange -East Portland Freeway Interchange section of I-5 south of Portland. The latter installations were made in 1976. Before these lowering devices were specified, high mast illumination was serviced by using a portable elevator. These fixed installations had several disadvantages. Principal among them was the reluctance of maintenance personnel to ride maintenance cars to the heights involved in servicing high mast lighting. Other disadvantages involved the difficulty of getting the elevator to the pole where access is not convenient and the potential hazard where the public has access to the pole and steps, cables and cabinets.
