Life in China 2016: A Picture A Day, July 11 – Since the stores in China are built “up” instead of “out” you must be able to navigate between floors with your shopping cart or “trolley”. In order to do this, there are flat escalators where the shopping cart wheels somehow catch and lock to keep it from moving. Many times, especially when the store is busy, they have employees at the bottom of an escalator to make sure you get off and moving smoothly, although I have never had a problem. They look similar to the moving walkways at airports only on inclines. I looked to see if there is a specific name for these, and it seems to just be “inclined moving walkway”, and it seems that the USA may be one of the few areas in the world that doesn’t have them??? So, now I’m curious, has anyone seen these in the USA, maybe in big cities? And, where have you seen them outside of the USA or China? They seem quite safe, although there was an accident in Shanghai in 2013 when a woman was killed by a runaway cart that was loaded with over 300 pounds of drinks! Other safety concerns are using other wheeled things like strollers where the wheels don’t catch and lock like the shopping carts do.
