Roosevelt Island Community Emergency Response Team (CERT) member Frank Farance reports on and shares photos from Roosevelt Island Tram Evacuation Drill held Sunday April 12.
According to Mr. Farance:
Roosevelt Island Tram Evacuation Drill: As Tram staff explained: there are many redundant and backup systems to return tram cabins to stations, including having the second tram pull up side-by-side -- evacuation like this is a last resort.
Mr. Farance explains evacuation procedure for lowering Tram Riders to the ground from the Tram Cabin.
The passengers are first fitted into a "diaper" that is attached to the pulley (which holds 9000 lbs), then they would drop down (slowed by centrifugal braking) while rescue workers on the ground use guide ropes to reduce swaying, and they land on the ground (the 5 mm cable supports passengers up to 900 pounds). Notice that while the diaper holding the passenger going down, a second diaper on the other side of the pulley goes up to ready the next passenger. See passenger drop video below.
The second part of the emergency drill is pulling the tram's haul cables back and swapping drive wheels (big orange gear) -- think of pulling a rubber band off a pulley. Here workers are bolting on sleeves onto the cables that are pulled back via hydraulic jack, which gives them enough slack to thread the haul rope on the backup drive adjacent to it (big yellow gear behind big orange gear). Truly amazing.
Mr. Farance also participated with NYC wide CERT Teams assisting following the March 26 East Village Building fire, explosion and collapse. He reports on the experience here.
