Efficiency of handling equipment reduces the service time of vehicles arriving at the container terminal. A simulation model of the operation of handling equipment allows reducing the time for diagnosis handling technique with its failure. The model constructed by means of apparatus of Petri Nets the formalism of Petri Nets provides the precision of definitions and reflects the structural and logical connection of the simulated events. The visualization and simplicity of Petri Nets allows the technician has no special training to use these models. This paper examines the reach stacker model, these types of machines that used in container terminals. A Petri Net simulating the operation of the reach stacker – hierarchical, has a built-in network positions. Hierarchy of networks identified position to ensure secure operation techniques, conflict situation, and analyzed solutions. Position having the chips are nodes, which can cause failures.
