Uptime hydraulic drive and therefore its reliability is a necessary aspect of the study, as the main mechanism for lifting devices is precisely hydraulic. Accordingly, this article focuses on the study of the reliability of the hydraulic drive lifts. To do this, consider some common connection between the laws of distribution of time to failure and the failure of a physical entity, namely, the failure rate is considered a schedule depending on time of use of hydraulic drive and explained the physical meaning of the failure rate. Also shows a diagram of the hydraulic drive lift and described the principle of operation of the hydraulic drive. Particular attention is paid to assessing the reliability of the hydraulic drive on the basis of the exponential law of reliability. Then compares the probability of failure-free operation of the mechanism for the different number of hours of operation of hydraulic drive. This theme is complemented by the modern method of examination and analysis of the causes of failures on the basis of the scheme of causality. In the first stage of the method is carried out calculation of the total index of the functional elements of the hydraulic drive reliability and assesses performance hydraulic drive, while refusing all elements of the system. The second step assesses the reliability of the hydraulic drive on the level of gravity of the manifest failure taking account of the refusal on the basis of calculations of indicators of elements of critical failures of hydraulic drive. In conclusion, given the results of the analyzes and conclusions of the calculations. It is a question how the reliability of the hydraulic drive with the passage of time and the reasons for this change, as well as notes which elements of the hydraulic drive have the largest and smallest functional reliability.
