The invention relates to the technical field of fluid working systems, in particular to a hydraulic control system for engineering machinery, which comprises a first hydraulic module arranged between a first cargo boom and a lifting platform and used for connecting the first cargo boom and the lifting platform and providing power for the first cargo boom; the second hydraulic module is used for providing power for the second cargo boom; the first triggering module is used for controlling the first hydraulic module to perform first preset action; the second triggering module is used for controlling the second hydraulic module to perform a second preset action; the supporting module is used for fixing the relative posture of the first lifting arm and the lifting platform; the central control module is used for controlling the operation of the crane; by means of the modules, the dumping direction of the damaged crane is guided, the controllability of the damaged crane is effectively improved, meanwhile, the loss of hoisting equipment is reduced, and therefore the safety of a hydraulic control system is effectively improved.

    本发明涉及流体工作系统技术领域,尤其涉及一种工程机械用液压控制系统,包括:第一液压模块,其设置在第一起重臂和起重平台之间,用以连接第一起重臂以及起重平台,并为第一起重臂提供动力;第二液压模块,用以为第二起重臂提供动力;第一触发模块,用以控制第一液压模块进行第一预设动作;第二触发模块,用以控制第二液压模块进行第二预设动作;支撑模块,用以将第一起重臂与起重平台的相对姿态固定;中控模块,用以控制起重机的工作;利用上述模块,对损坏的起重机的倾倒方向进行引导,在有效提升了起重器损坏时的可控性的同时,降低了起重设备外的损失,从而有效提升了液压控制系统的安全性。
