In this paper, the advanced electro-hydraulic control plan of mechanical transmission system for construction machinery abroad is introduced. The electro-hydraulic proportion technology is discussed. Based on mechanical transmission system for construction machinery in China, an electro-hydraulic control plan is studied and analyzed, and an electro-hydraulic proportion technology is applied in transmission system of construction machinery. The transmission case of construction machinery is controlled by applying electro-hydraulic proportion technology, and an optimal fitting for pressure-time curve of transmission case is made.
