7 Reviving the Old Escalator

Reviving the Old Escalator

Posted on January 31, 2013 by team


The whole subway station “Polytechnic Institute” in Kiev was reported to be closed soon only due to the malfunction of the escalator. It does not seem too reasonable, right? But why is repair of an escalator so difficult to do? Let us check this out.

The process may take one month or two. The tunnel escalator is a complex machine with a huge number of moving parts. There are more than 600 stairs and about ten thousand of bearings. Many parts are subjected to heavy wear: if the escalator works no-nstop, it will overcome twenty eight thosand of kilometers. Overhaul must be done every 170 thousand of kilometers. If it suddenly breaks the consequences can be rather bad.

During the overhaul it is almost fully disassembled in the strict order: stairs, pulling chains, guide rails, etc.

The orther day they finished the dismantling of the parts of the escalator under repair. Almost all of them were brought to shops of the escalator service: each detail must be disassembled, cleaned, examined and repaired, if necessary.

The most interesting place is hidden under the feet of passengers – the turbine hall.

The disassembled escalator looks like this now.

    But yet my wife tells me russia is so advanced and modern compared to america. That thing is awful looking 50’s technology if not earlier right there. Government really likes to contently upgrade there facilities to help the people it seems

    When they have the room they use it. Makes access and maintenance easier. Besides, Kone are hardly known for reliability.

    The “assistants” need to have their water changed. Red-Ear Sliders are native to the southern US but are popular all over the world.
