履带式起重机与电驱动抓斗动力系统改造技术

Retrofit Technology of Crawler Crane and Electrically Driven Grab Power System

以履带式起重机与电驱动抓斗为研究对象,简述两者动力系统二合一改造技术,主要进行动力系统改造的可行性分析,阐述对抓斗开闭斗主油路、抓斗主油管揽轮油路、伺服油路和双卷扬同步油路等性能要求进行液压设计和改造技术。

Taking the crawler crane and electric drive grab as the research object, this paper briefly describes the two-in-one power system transformation technology, mainly carries out the feasibility analysis of power system transformation, and expounds the hydraulic requirements for the main oil circuit of grab opening and closing bucket, the main oil pipeline of grab, the pulley oil circuit of grab main oil pipeline, the servo oil circuit and the double hoisting synchronous oil circuit. Design and transformation technology.
