One of the 4 2009 custom Schindler HT 400A Lifts got modded by Hissgruppen and it's noisy that i'm riding that, the 2nd one hasn't custom floor pass chime and crappy, the 3rd one and the 4th one are modding by Hissgruppen. The 1st one used to have the high pitch chimes but now silent, the 2nd, 3rd and 4th ones which have normal pitch chimes. There are 4 Heads Towers, one is red, one is green, one is blue and the one is yellow. In the green one have the custom 4 2009 Schindler HT 330A Main Lifts (2 are modding and 1 modded), and there's a 2 Hissgruppen Service Lifts. In the yellow one have the 2 2009 Schindler Eurolift Main Lifts, and there's a 2 Schindler HT 500A Service Lifts. In the red one have the 4 2019 OTIS Gen2 Main Lifts, and there's a 2 Schindler M-Series Service Lifts. In the blue one have the 4 2007 OTIS Series 5 Main Lifts, and there's a 2 Hissgruppen Service Lifts.
