| Abstract: | According to design requirements and application characteristics of NS020 type 20 t railway crane, advanced hydraulic control technologies, such as power control technology of SR total power variable hydraulic pump, high precision control technology of electric proportion and energy saving control technology of load sensing, are adopted in hydraulic system of NS020 type 20 t railway engineering crane. The advantages of these advanced hydraulic control technologies are compared by their principle analyses, which is good for exploration and practice for medium and small tonnage railway engineering cranes and railway engineering machinery adopting the advanced hydraulic control technologies, such as power control technology of SR total power variable hydraulic pump, high precision control technology of electric proportion and energy saving control technology of load sensing. |
