Isyemini I. Increasing of effectiveness of protective systems of overhead type cranes by using of pneumohydraulic buffers

Object is a process of overhead type cranes running into an end stops. Research objective is an increasing of effectiveness of the protective systems of overhead type cranes. Methods: mathematical model approach, experimental method, method of mathematical statistics. Theoretical and practical results: the effectiveness of the protective systems of overhead type cranes at the expense of decreasing of the deceleration by using pheumohydraulic buffers is increased. Scientific novelty: The further development to the mathematical model of overhead type crane with load running into an end stops by using pneumohydraulic buffers is given.
