Kone, with operations in Moline and Coal Valley, announced today it has been awarded a contract to modernize 29 escalators and moving walkways at the world’s busiest airport — Hartsfield-Jackson Atlanta International Airport.

The project features 15 Kone EcoMod escalators and 14 moving sidewalks, all of which will be manufactured at Kone’s Coal Valley plant.

Kone said its relationship with the Atlanta airport spans more than 30 years. It has served as the airport’s maintenance provider since the airport was built in 1979.

“We are looking forward to continuing our strong relationship with Hartsfield-Jackson,” said Larry Wash, Kone’s executive vice president and area director for the Americas. “Our award-winning escalator modernization solution will help the airport increase capacity, save energy and improve reliability without interrupting passenger traffic.”

Hartsfield-Jackson has been the world’s busiest airport for passenger traffic since 1998 and by number of landings and take-offs since 2005. It accommodates more than 250,000 passengers and 2,500 arrivals and departures daily.

Kone said work on the project will begin in May and is expected to be completed in February 2016. The value of the contract was not disclosed.
