Looking at any modern city from a bird's eye view, one can be surprised at the richness of its infrastructure. Practically wall to wall with residential buildings can be located buildings of various institutions, industrial enterprises, high-rise business centers, department stores and other facilities. Not to mention the numerous bridges and various towers. Indeed, the building density of modern cities is amazing. All this complicates the construction and repair work. The more landscaped the area, the more difficult it is to use special equipment.
For this, there are treetop activities that are often carried out by people with extreme training - climbers, climbers, cavers, who decided to make their dangerous hobby a major specialty. With success and high efficiency, they replace bulky mechanisms with a reliable rope, an assembly belt, and virtuoso techniques for working on the steep wall of the βstone jungleβ.
Although now more and more training centers for industrial climbers are being opened every day, to this day, treetop work is in most cases carried out by athletes who have more than once climbed the highest mountain peaks or descended into the abysses of the deepest caves. Of course, all of them previously receive special construction skills for high-altitude work.

Work at heights, in other words, treetop work, is various operations performed at least five meters above the surface of the earth, floor or working floor. That is, these are working conditions where a person and his insurance are left alone with the space extending below. Dangerous job! Therefore, labor protection when working at height puts forward special safety requirements. The main means of protection against falling, according to the rules for high-altitude work, are the safety belt and safety rope. To protect the head, a special helmet is provided, which must first be checked and for which there must be a quality certificate.

Climbing work has its own interesting history. So, even in severe blockade times, a group of Leningrad climbers (now they would be called industrial climbers) carried out the most difficult task of disguising the golden domes of the cathedrals, which deprived the Luftwaffe pilots of the opportunity to conduct targeted bombing in St. Petersburg churches. Now one can only guess what kind of appearance would now have in the cultural and spiritual capital of Russia, if not for the selfless and heroic work of the first domestic industrial climbers.
An interesting fact is that high-altitude climbing work was officially legalized in Russia in 2001, when this profession was entered in the corresponding register and thereby legalized. Although such a complex and dangerous specialty, of course, existed long before its official recognition.
Today, the services of industrial climbers are extremely sought after for installation, and facade, and restoration, and cleaning works. And also when lifting bulky goods in hard to reach places. Often, only a professional industrial climber with psychological training for working in unsupported space and special skills can install an advertising banner, clean the roof of a high-rise building from ice and snow, or wash the windows of a skyscraper.
