Rolling stairs drive assembling at the new underground station “Bukharestskaya”, Saint Petersburg

On September, 24th – 25th, 4 drives of rolling stairs E75T (weight of drives is 27tons each) had been moved in and assembled on the basement in entrance hall of the underground station “Bukharestskaya”, St. Petersburg, being under construction.
The works were executed for company SMU-9 MetroStroy. The gantry technology was used instead of standard crane lifting which allowed the construction workers start the ceiling assembling two months ahead of scheduled time.
