World War II
Proyshlenny climbing or "promalp" – a technology implementation work at height in industrial and other facilities in which the workplace is achieved by raising or lowering a rope, or using other climbing methods for insurance and travel. This technology allows the employee to gain access to the most inaccessible places without scaffolding, cradles or lifting equipment. Scope industrial mountaineering is very broad, but mostly service industry climbers use in construction and cleaning and maintenance. The main types of work: washing windows, cleaning and washing of facades, facade work, painting and repairing the facades, cleaning and snow removal of icicles from the roofs. In addition, industrial climbers come for help if you need to install or dismantle the air conditioner, lift oversized furniture through a window sealed seams and more. History of industrial alpinism has more than one hundred years.
Back in the sailing navy sailors carried out various works in a suspended state on the ropes. It is here in industrial alpinism came many nodes. In our country the first industrial alpinism used during World War II. In the harsh conditions of blockade of Leningrad mountaineers to carry out complex masking work on such projects as the spire of Peter and Paul fortress and the dome of St. Isaac's Cathedral. On the upper levels of these structures was not possible to use the internal building structures – too closely there for people. It took an outside, almost vertical surface of the roof. Unique technical event necessitated the development of entirely new ways of insurance and the movement of people on top.
It turned out that the climbing experience can not simply defer to the construction site. And yet, it is the first mountaineers and climbers have developed the technology of work rope way. These developments were more life than similar efforts made by the professional builders who have no experience in the sports pitch.
