Wind Speed And Panel Design Blamed For Tram Incident

Portland, Or. –  A panel that fell from the Portland Tram  back in December was likely the result of  the panel’s design, combined with wind speed and direction that day. That’s according to an independent engineering report sought by the Portland Bureau of Transportation. The panel hit a pedestrian who declined medical treatment.

PBOT says it and OHSU have made changes to improve tram safety. PBOT says tram crews have replaced existing carbiners and wire tethers on all panels with enhanced versions. It will no longer allow the tram’s air vents to be open if wind speeds are higher than 20 mph. The tram will  not operate at all if winds are sustained at more than 30 mph.

In addition, a customized bolt and tether system will be installed this summer.

The tram is owned by PBOT and operated by OHSU.
