The invention discloses a hydraulic control operation crane main pump power control method and a hydraulic control operation crane. The control method comprises the following steps: acquiring a preset power control curve and an action signal sent by an orientation detection device; determining a load type according to the action signal; selecting a target power control curve from preset power control curves according to the load type; performing power matching of the hydraulic control operation crane according to the target power control curve; wherein the preset power control curve comprises a plurality of candidate power control curves, and the preset power control curve is a relation curve of the rotating speed of the engine and the current of the oil pump. Different load types are matched with the corresponding target power control curves, so that differential control of the power of the oil pump can be realized, power matching of different loads can be realized more simply and accurately, and the working efficiency of the hydraulic control operation crane can be improved.

    本申请公开了一种液控操作起重机主泵功率的控制方法及液控操作起重机。该控制方法包括:获取预设功率控制曲线以及方位检测装置发送的动作信号;根据动作信号确定负载类型;根据负载类型在预设功率控制曲线中选择目标功率控制曲线;根据目标功率控制曲线进行液控操作起重机的功率匹配;其中,预设功率控制曲线包括多条候选功率控制曲线,预设功率控制曲线为发动机转速与油泵电流的关系曲线。本申请通过将不同的负载类型与对应的目标功率控制曲线匹配,可以实现油泵功率差异化控制,更加简单且精确地实现不同负载的功率匹配,从而能够提升液控操作起重机的工作效率。
