1958年底在总路线的光辉照耀下,为了精简自驱式动力头用的进给液压控制板的结构,减少零件数量,我所在y424进给液压控制板的基础上改进设计出了ly4241进给液压控制板。从液压原理上看,它能实现y424的一切动作。基本性能和y424相同。 设计通用的液压控制板工作,对当时的我所液压组来说还是陌生的。在所部有关负责同志的指导下,液压组同志经过努力和反复修改才设计出来。
At the end of 1958 in the brightest shine of the general route, in order to streamline the structure of the feed hydraulic control panel for self-propelled power head, reduce the number of parts, I have improved the basis of the hydraulic control board y424 designed the ly4241 feed hydraulic control board. From the hydraulic principle point of view, it can achieve all the actions y424. The same basic performance and y424. The design of a common hydraulic control panel work, at the time of my hydraulic group is still unfamiliar. Under the guidance of the relevant responsible comrades, the comrades of the hydraulic group have only designed them with hard work and repeated modifications.
