Old metro stations
Many major cities of the world are faced with transport problems of old subway systems. Some of these systems were built more than a hundred years ago and require immediate modernization to meet modern requirements and standards. In many metro station systems, only elevators are equipped with elevators. These are usually wide lifts, slowly moving between the levels of the station. Passengers are forced to wait for a long time, and the total throughput of the station is very limited because of this. The use of spiral escalators at such stations will increase their throughput and safety. They will not require additional costs, since it will be possible to leave existing elevators of elevators and not touch the architecture of the station.
New metro stations
During the construction of new metro stations, it is extremely important to reduce the volume of the extracted soil. Stations are usually built in a lively center of the city, where each cubic meter of soil creates a problem in terms of logistics and the cost of transport from the construction site and to it. The amount of concrete going to the construction of tunnels directly affects the cost of the station in connection with the costs of delivery and laying.
It is important to note that the standards require: in each new metro station, at least one elevator shaft for disabled passengers should be provided for at least one metro station. In this case, the use of spiral escalators only requires expanding the elevator shaft so that escalators and elevators are located in it.
