Kiev Metro. Escalators.

We plunge into the depths of the oldest and most interesting machine halls Kiev subway escalators - "Khreshchatyk" and "Arsenal". Indeed, the devices impress with their size and power metal, as well as sophisticated design, which, even after 50 years, provides high availability and reliability.





We descended into the turbine building. Usually, a relatively small room semicircular shape where the engine control system and actuators. All functions in the automatic mode using a single remote control and centralization.



The engine is mated with a gear via the hydraulic brake. The gearbox is connected with the main gear shafts and gears handrails. The size of these systems on old machines are very impressive, which is why they are staggered.



Depending on the type of escalator diameter gears may vary, ranging from 2 to 3 meters. It is situated in a powerful frame.

For that - technological mine lifting.



Currently, management escalators osuschestvalyaetsya using a computer system BPCS, but part of the control circuits and the power is still displayed in the old cabinets since the discovery of the first stage.



It looks fascinating.

Near the entrance to the tension of the upper chamber of the march. This is - a small dark room where there are lower gears and prigruza. The tension is low and narrow walker.



From here such doors.
