Don't look down! Two of the Russian daredevils perform their vertigo-inducing exercise routine on the beam of a crane hundreds of feet high
Fearless: Two Russians balance precariously on a railing despite having absolutely no safety equipment
Long drop: Clinging to sides of the beam using only the strength of his finger tips one of the climbers spins round to take in the gravity of his position
Look one hand! One of the two men grins up as he gives the thumbs-up while still dangling from the beam
Gymnast: A man performs a hand stand at the very top of the structure
Are you quite sure about this? He rubs his chin as he performs what appears top be a yoga pose - standing on one leg in high wind
