The load limiting control for enginehydraulic systems is a kind of intelligent electrohydraulic control technology that automatically adjusting the variablepump hydraulic system according to load. The principle of load limiting control system was introduced. The conventional loadsensing system and LUDV loadsensing system were analyzed on the principle and characteristics. The crane hoisting system was taken as the experimental subject. The experimental results are thought to be in accordance with the analysis of the flow characteristics of the traditional loadsensing system, thus providing reference for optimizing the control strategy of the load limiting control system.
