Airport Express Station at Sanyuanqiao in Beijing

I will be staying at Hotel Ibis Peking Sanyuan. May I know if there are lifts or escalators from the road level down to the airport express station level at Sanyuanqiao? If there are no lifts or escalators, how steep are the stairs - are there many? I will be carrying a big suitcase and a cabin bag. Also, do my bags have to go through an xray security check before I board the train?

Thank you.
