A red line on the pump indicates whether or not the pad is secure. Working the pump removes the air between the pad and a surface, causing the pad to stick.

The product consists of a rubber pad and a manual pump. Each of those cups costs between $80 and $95 and is at most 10 inches in diameter, with a maximum load capacity of 175 pounds. #ItsWhatWeDo /ue07uc1zpn- NYPD NEWS August 11, 2016Īccording to website Inverse, the Trump Tower climber appeared to use suction cups sold by the industrial supply company Zoro, meant for lifting objects. While the world watched, NYPD training & the planning by ESU, HNT + more resulted in a safe resolution.

And in May, professional climber Sierra Blair-Coyle ascended a 33-story building in South Korea using LG vacuum cleaners with suction pads attached. The 55-pound unit sends pressurized air from tanks strapped to the climber's back to pads attached his or her hands and feet, creating a vacuum effect.
In the late 1990s, German designers unveiled the Gekkomat, named for the lizard that can traverse smooth surfaces. In the 1980s, Dan Goodwin used suction cups to scale buildings in cities including Chicago, Dallas and Tokyo. Rogata wasn't the first to climb a tower this way. The higher the elevation, the less pressure exists outside, making a suction cup less reliable, so it's a good thing Rogata made it only about a third of the way up Donald Trump's 68-story skyscraper. Removing the air inside can help reduce the pressure, which can be done with a pump or, for a smaller suction cup, like the kind that sticks to shower tiles, by pushing down on it. Here's how it works: Suction cups stick to a surface when the pressure inside the cup is less than the pressure outside it. Stunt's like Rogata's may sound like something out of Mission: Impossible ( or Looney Tunes), but as the television show MythBusters once demonstrated, it's actually just science. The incident lasted hours, until police yanked him inside. It wasn't Superman it was Virginia teen Stephen Rogata, scaling Trump Tower with four suction cups. The scene was fit for a superhero movie: On August 10, a crowd of New Yorkers stood in the street, transfixed by the spectacle above.
