The article describes reason of traumatism at the building site, discusses negative influence of load swing, in construction and hoisting work. Also there are some series of events to prevent the load swing presented. One of those ways in development of modern construction equipment is a device development, that helps increase safety and reliability and improve productivity. In the article there are results of researching the influence of construction shown. The author shows the mechanical damper like light weight added, which decrease period of oscillation flexible pendant to the amount, depends on the place of damper through the length of pendant. In the article the problem of holding comparison between inventions, describing ways, they works, pointing their distinctions and noticing their limitations. Much attention is given to invention, in which the operation principle is the gyroscopic inertia. Also is given a comparison of ways to prevent the load swing on flexible pendant by influence at controls of crane and by using the computer systems, which predict the value of horizontal displacement of joint pendent to the jib in consequence of jib deformations under the influence of the load weight and gives a signals to controls. The main goal of research is analysis and finding the most effective ways to damp load vibrations, the most effective inventions, created to stop the load and also to provide reliability, safety and efficiency construction works at the building site.
