A boom lift system comprising: a main conduit; a pump-motor arrangement having a motor operable to drive the pump to move fluid through the main conduit; first and second actuators in fluid communication with the main conduit and actuatable in response to first and second user inputs to perform a hydraulic function via fluid; a valve arrangement configured to control a flow of fluid from the main conduit to the first and second actuators; and a controller programmed to selectively actuate the valve arrangement in response to the first and second user inputs. When the controller receives both the inputs, the valve arrangement is actuated by the controller to change a fluid flow rate to each of the first and second actuators. When the controller receives only one of the first input or the second input, the controller changes the flow rate output of the pump.

    一种吊臂提升系统,包括:主导管;泵‑马达布置结构,该泵‑马达布置结构具有马达,该马达可操作以驱动泵移动流体通过主导管;第一和第二致动器,该第一和第二致动器与主导管流体连通,并且可响应于第一和第二用户输入而致动,以经由流体执行液压功能;阀布置结构,该阀布置结构被配置成控制流体从主导管到第一和第二致动器的流动;以及控制器,该控制器被编程为响应于第一和第二用户输入而选择性地致动阀布置结构。当控制器接收到所述输入两者时,阀布置结构由控制器致动,以改变到第一和第二致动器中的每一者的流体流率。当控制器接收到第一输入或第二输入中的仅一者时,控制器改变泵的流率输出。
