Therein lay the reason: the tower, which was to house radio transmitters, was being built without the use of cranes. The sections were assembled on the ground, then hoisted up by cables and secured to the section below. While the fourth section was being installed, one of the cables snapped and it fell, sustaining damage. But without Shukhov, it was impossible to complete the tower. Vladimir Shukhov's design ensured that a signal could be transmitted 10,000 kilometers!
