With the increase of high-rise construction the volumes of high-rise services on maintenance and monitoring of high-rise buildings also grow. Construction and lifting-transport machines are being produced, which require maintenance on height. New types of work at height appear, which can only be done only by steeple jacks or industrial climbers. Analysis of accidents during high-rise services shows that often the use of unreliable means of protection against falls from a height or misuse of these means leads to emergency situations, as well as errors in the organization and technology of works performance at height. In this regard during the development of safe technologies for high-rise works, creation of new designs and types of personal protective equipment (PPE) against falls from heights and during their production, particular attention should be paid to reliability of these means, as well as the correctness of their use. In order to determine the reliability of personal protective equipment against falls from a height, as well as for certification of these means by the scientific and production methodological center “Industrial alpinism” of MGSU special stands were created for dynamic studies of these means. Dynamic characteristics are investigated by a falling cargo or dummy.

Today the technologies of trenchless reconstruction of pipelines are becoming
more and more widely used in Russia and abroad. One of the most perspective is methods is shock-free destruction of the old pipeline being replaced with the help of hydraulic installations with working mechanism representing a cutting unit with knife disks and a conic expander. A construction of a working mechanism, which allows making trenchless reconstruction of pipelines of different diameters, is optimized and patented and its developmental prototype is manufactured. The dependence of pipeline cutting force from knifes obtusion of the working mechanisms. The cutting force of old steel pipelines with obtuse knife increases proportional to the value of its obtusion. Two stands for endurance tests of the knifes in laboratory environment are offered and patented.
