Methods and systems for detecting unbalanced payload condition in machines

Abstract:

A method for detecting an unbalanced payload condition in a machine is disclosed. The method includes detecting, by a first sensor, a pressure exerted on each of one or more struts in the machine by a payload. The method further includes detecting, by a second sensor, one or more operational parameters associated with machine. Furthermore, method includes determining, by a controller, a center of gravity of the payload based on detected pressure, the one or more operational parameters, and one or more dimensions of the machine. Additionally, the method includes determining, by the controller, a force being exerted, by the payload, on each traction member of the machine based on the center of gravity of the payload. The method further includes detecting, by the controller, the unbalanced payload condition when the force, being exerted on at least one traction member of the plurality of traction members, exceeds a threshold value.
