An Electric Hydraulic Driving System of Lifting Platform for Composite Roller Casting

To solve the engineering problem that the present driving system of lifting platform for composite roller casting works with high failure rate, this paper has analyzed the cause of the failure, summarized all kinds of popular driving system of lifting platform, designed a set of proportional valve controlled electric hydraulic driving system, and tested its performance in hydraulic modeling and simulating software AMESim. Results show that the performance of the designed system is good enough to meet the present technical requirements. The design of the driving system is also a reference for other lifting platform with long stroke, heavy load and high accuracy.
