System and method for estimating a payload of an industrial machine
A method of determining payload data of a mining machine having a bucket and a handle. Wherein, the bucket and handle are rotatably coupled via a pin and an actuator. The method includes sensing, via a first sensor, a first force associated with the actuator and sensing, via a second sensor, a second force associated with the bucket. The method further includes determining, via a controller, a rotational angle of the bucket and determining, via the controller, payload data based on the first force, the second force, and the rotational angle.
