do you have escalators for wheelchairs?

the elevator was under repair so someone accompanied us to the service elevator. as in, that area at the back where the delivery trucks go. when we came out at the correct floor, we were told to just follow the exit signs. however, this long narrow corridor turned left, right several times it felt like we were in a maze. then there was one corner where it was so narrow the wheelchair just couldn't pass through. thankfully, a female employee happened to be there with an empty grocery cart. we decided mother would stand up and hold on to the grocery cart while we lifted the wheelchair over the concrete curb/bump curb at the base of the walls. you could see so many scratches and chips on both walls, while the paint on the concrete at the bottom has worn off, evidence that that part of the passageway is just too narrow for the many things that have passed through there "behind the scenes" that most people don't see. i wish we had wheelchair-accessible escalators here, so the general public don't have to use the service elevators and go through the "winding secret alleys" inside buildings. do you have escalators for wheelchairs when the elevator is out of service?
