EN The joint model of the system operation process and the system multi-state reliability is applied to the reliability and risk evaluation of the container gantry crane. The container gantry crane is described and its operation process unknown parameters are identified on the basis of real statistical data. The mean values of the container gantry crane operation process unconditional sojourn times in particular operation states are found and applied to determining this process transient probabilities in these states. The container gantry crane different reliability structures in various its operation states are fixed and their conditional reliability functions on the basis of data coming from experts are approximately determined. Finally, after applying earlier estimated transient probabilities and system conditional reliability functions in particular operation states the unconditional reliability function, the mean values and standard deviations of the container gantry crane lifetimes in particular reliability states, risk function and the moment when the risk exceeds a critical value are found. he joint model of the system operation process and the system multi-state reliability is applied to the reliability and risk evaluation of the container gantry crane.
