Portland Aerial Tram's maintenance ahead of schedule
The $300,000 maintenance project on the Portland Aerial Tram will finish earlier than planned, putting the tram back in business by Monday, July 9, three weeks ahead of schedule.
The tram has been out of operation since June 23. The project was originally supposed to conclude July 30.
Doppelmayr, an Austrian-Swiss company that specializes in tram maintenance internationally, has been working on the tram's four main stationary track ropes. Doppelmayr U.S.A contracts with Oregon Health and Science University to operate the tram.
Crews worked 20 hours a day in two shifts. According to the Portland Bureau of Transportation, the repair workers used innovative repair techniques and utilized the good weather to finish the project in 16 days rather than five weeks.
Crews alternated the ropes that the cars ride on, carrying passengers between the two stations each day. Each track rope carries about 124,000 pounds of tension. To alternate each rope, crews will shift each rope downhill three feet at a time until 150 feet of the rope has been cycled through.
Brett Dodson, director of Tram, Transportation and Parking at OHSU said this sort of project must happen every 12 years.
On average, 10,000 people use the tram as their mode of transportation from the South Waterfront to Marquam Hill and back every day.
The tram will resume normal hours and operations starting 5:30 a.m. Monday. Tram shuttles will continue to run through July 11 and the bicycle valet will continue operations at all three temporary locations through July 16.
