Abstract
A work machine includes a mechanical arm. A work implement is coupled to the mechanical arm to receive a load. A hydraulic actuator moves the arm between a lower position and an upper position, wherein a distance between the lower position and the upper position is a travel distance of the mechanical arm. A sensor unit is configured to sense 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 valve 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. The controller is also configured to adjust the upper position to reduce the travel distance in response to the load being at or above a threshold value.
