Safety ensuring of the rail lift and transport facilities at the track ends

Abstract

The dead-end stops that prevent the descent and destruction of rail lift and transport facilities are used to ensure their safety. They are shock type, shockless type and combined. The most promising are the dead-end stops of unstressed type, since the main task of the dead-end stop is to stop the rail type device at the minimum distance. The probability of the crane overturning in the longitudinal or transverse planes of the track will depend on the "smoothness", "softness" of the braking. To improve the "smoothness" and consequently the braking safety, the dead-end stop design with the self-reinforcement effect of the resistance forces work is proposed and that can be used both for lifting and transport, and for main rail systems. Analytical dependence for the design calculation of the dead-end stop according to its main functional characteristic was obtained. The calculated dependency includes all the basic parameters allowing to determine its dimensions and configurations of the power elements and is the basis for the development of a diagrammatic layout, a general view drawing and a subsequent refined calculation of the dead-end stop design.
