An excerpt of our hotel tour with Beth Carman along with JP (from Daly Seven Hotels) at the Hilton Garden Inn in Greensboro, NC (I-40 Wendover Ave exit) which is right next door to the Holiday Inn Express that we also got to tour and see the Dover Elevator machine room there as well. (You can check out the video of Dover Machine Room at this link https://youtu.be/RagqxWF4AlE ) This video at HGI actually has an excellent view of exactly what happens with the hydraulic oil in the elevator tank when the Otis Series 5 elevators are in motion. Hope you enjoy this and stay tuned for a full hotel tour of HGI coming soon to my YT Channel. Special thanks to JP and all the fine folks at Daly Seven for making us so welcome and giving us a couple of great tours including the opportunity to see hydraulic pumps in action.
