Q:How much should the verticality of a tower crane be controlled? Thank you
No, the wind speed is not more than 3m/s, the independent state tower (or attached state highest attachment point above the tower axis) lateral verticality tolerance is 4/1000, the highest tower axis perpendicularity allowed attachment line below the point of difference is 2/1000.

Q:1000 paper cranes question?
Consider what you would like your 100 cranes to mean. Attach strings to your 100 cranes and then hang them in a tree etc so that the wind may carry your prayers where they need to go. Then start again to create the 1000 paper cranes you want for your wedding. PS: The making of the paper cranes involves an act of faith, not the right colour to match your wedding plans. In Japan, the crane represents peace and healing. When we consider the famous Japanese art-form of paper folding (origami) the crane comes to mind before all else. Sadako and the Thousand Paper Cranes (1977), a non-fiction children’s book written by American author Eleanor Coerr, tells the story of young Sadako Sasaki who lived in Hiroshima at the time of the atomic bombing. Sadako developed leukaemia as a consequence, and lived out the remainder of her short life in a nursing home desperately trying to create one thousand paper cranes. Supposedly, if someone could make a thousand paper cranes his/her wish would come true. Sadako wanted to live. Sadly, she only managed to fold 644 cranes. After her death, friends and family folded the remainder, and buried her with the one thousand paper birds. Today, a statue of Sadako holding an enormous golden origami crane stands in the Hiroshima Peace Park. People regularly leave paper cranes. The plaque on the statue reads “This is our cry. This is our prayer. Peace on Earth.”

Q:What makes a crane so strong?
Cranes are built using a structural technique called a truss which is characterized by looking like a series of triangles connected together. That structure prevents the members from having to resist any bending loads. All of the truss members experience only tension and compression, no bending. That is an extremely efficient structure which is why they can be so strong without being monstrously heavy. Or if you prefer the short answer, engineers make the crane so strong.
