Abstract
A work machine includes a mechanical arm and a work implement coupled to the mechanical arm. The work implement is configured to receive a load. A hydraulic actuator is coupled to the mechanical arm to move the arm between a first position and a second position. A sensor unit is configured to detect the load in the work implement. A valve is in fluid communication with the hydraulic actuator for supplying a fluid output to the hydraulic actuator. A controller is in communication with the value and the sensor unit. The controller is configured to transmit a control signal to the valve to adjust the fluid output to the hydraulic actuator, and wherein the controller is configured to derate the fluid output in response to a signal from the sensor unit that a load is at or above a threshold value.
