Repairing High-Voltage Power Lines

Haverfield Corporation, PA.

is a commerical company initially established to provide to electric utilities general purpose aircraft charter service using helicopters. In 1984, Haverfield patented a work platform that is attached to the helicopter so that a lineperson can work on energized lines from the platform as the helicopter hovers adjacent to the powerline. The site contains a series of linespeople at work. This is the same company as the photo for the chapter heading.
