Abstract

A boom lift system includes a primary conduit, a pump-motor arrangement having a motor operable to drive a pump to move a fluid through the primary conduit, first and second actuators in fluid communication with the primary conduit and actuatable in response to first and second user input to perform hydraulic function via the fluid, a valve arrangement configured to control flow of the fluid from the primary 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 of the inputs, the valve arrangement is actuated by the controller to vary the flow rate of fluid to each of the first and second actuators. When the controller receives only one of the first input or the second input, the controller varies a flow rate output of the pump.
