Schindler is the world's second largest elevator manufacturer after Otis and the "Forbes Global 100 Most Innovators", with an average of more than 1 billion people taking Schindler's elevators and escalators every day, and has become an escalator supplier for the Beijing Olympic venues and the Shanghai World Expo in 2008 and 2010. Schindler 3300 series villa elevator is a global synchronous model, and 70% of the core components are imported from Switzerland. The steel belt traction method makes it less noisy and consumes less energy than traditional wire rope traction elevators, making the 3300 AP the first elevator to receive the A-level certification of the VDI4707 energy efficiency assessment. The use of touch screens also makes this elevator quite avant-garde. In addition to 3300, Schindler Villa Ladder also has two series, Villa and VIGO, both of which use 220V household power supply, which is more flexible in the choice of load capacity. However, Schindler's main business is still commercial elevators, and the orders and after-sales maintenance for individual users are not perfect.
