PDF file (Download)МРНТИ 55.51.31, 73.41.39 №2 (2020г.) Shamey E., Smirnov V.M., Ishchenko A.P. The article is an analysis of information from open sources on accidents of self-propelled boom cranes, as a result of which the relationship between the rollover and the deviation of the cargo ropes from the vertical was revealed. A review of modern safety device systems has shown that as part of their functions, they do not have the function of limiting the force in the cargo ropes when they deviate from the vertical. Performed research discovered that if certain provisions of cargo ropes from the vertical, even with constant effort into them, accompanied by the growth of overturning moment, which is essentially outruns the exertion in the hydraulic cylinder of the boom, which leads to a lack of timely control and commands system safety devices. A method for solving this problem is proposed, which provides for the installation of an additional sensor that detects the deviation of cargo ropes from the vertical, with the appropriate calibration and operation algorithm. Keywords: self-propelled boom crane, cargo ropes, rollover, safety device system. Eventually
