Decrepit and bumpy Soviet elevator @ Yerevan, Armenia

Something is wrong with this elevator! It shakes a lot when above floor 3, one of the guide rollers must be broken (you can hear a squeaking noise). What's scarier is the very strong bump when stopping on the higher floors. It made me jumpscare many times! The cab walls are not original. There are 4 entrances in the building, 2 elevators have been replaced, 2 are original. Check out the other original elevator here (it is in much better shape) :    • 1970s Soviet elevator in good shape! Yerev...   ========= Technical information ========= Manufacturer: unknown (ShLZ ?
