Abstract
A work machine may have a payload overload control system. The system may include a payload carrier and a lift mechanism configured to raise and lower the payload carrier. The system may further include a payload monitor configured to determine a payload in the payload carrier. The system may also include a controller configured to compare the determined payload with a predetermined maximum payload and to selectively control lift of the payload carrier by the lift mechanism based on the comparison between the determined payload and the predetermined maximum payload.
