Abstract: A payload measurement system can be used to measure the payload added to a machine supported on a plurality of walking beams. A plurality of load cell sensors is mounted to the walking beams in locations where, when the walking beam bends, the sensors are placed under load. The load cell sensors include a symmetrical strain bar having first and second mounting ends connected by a connecting span, wherein the end thickness is greater than the span thickness of the connecting span. The connecting span is disposed between and spaced apart from an upper plane and a lower plane with which the surfaces of the mounting ends are aligned.

Abstract: According to some implementations, a magnetic sensor may include a communication device; a magnetic switch; and a controller configured to: determine whether the magnetic switch is actuated by a magnet associated with the bucket tooth; generate, based on determining whether the magnetic switch is actuated, a message concerning an attachment status of the bucket tooth; and cause the communication device to wirelessly transmit the message.

Abstract: A method for operating a machine adapted to transport a load during a work cycle is disclosed. The method includes determining a first stationary state of the machine, and causing sensors to start transmission of first signals. The first stationary state corresponds to a first segment of the work cycle, and the first signals indicate a weight of the load during the first segment. Further, the method includes determining a moving state of the machine corresponding to a second segment of the work cycle, and causing the sensors to terminate transmission of the first signals. Furthermore, the method includes determining a second stationary state of the machine, and causing the sensors to start transmission of second signals. The second stationary state corresponds to a third segment of the work cycle, and the second signals indicate a weight of the load during the third segment.
