Payload overload control system
First Claim
Patent Images
1. A machine payload overload control system comprising:
- a payload carrier;
a lift mechanism configured to raise and lower the payload carrier;
a payload monitor configured to determine a payload in the payload carrier; and
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 by imposing a lift limit on the lift mechanism based on the comparison between the determined payload and the predetermined maximum payload.

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.

13. A method of controlling work machine payload overload comprising:
-
determining a payload carried by a machine in a payload carrier; comparing the determined payload to a predetermined maximum payload; selectively controlling lift of the payload carrier by imposing a lift limit on a lift mechanism configured to lift the payload carrier based on the comparison. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A machine having a payload overload control system comprising:
-
a power source; a traction system; a payload carrier; a lift mechanism configured to raise and lower the payload carrier; a payload monitor configured to determine a payload in the payload carrier; and a controller configured to compare the determined payload with a predetermined maximum payload and to impose a lift limit on the lift mechanism when the following conditions are met a) the determined payload exceeds the predetermined maximum payload; b) a selected travel direction of the machine is selected from the group consisting essentially of neutral and reverse or the determined ground speed in a forward direction is no higher than zero; and c) the lift mechanism is raised above a predetermined limit; the controller being further configured to remove the imposed lift limit when the lift mechanism is lowered below a predetermined reset height. - View Dependent Claims (26, 27, 28)
