Systems, methods, and apparatuses can determine weight of a machine using rolling resistance. The machine may be electrified, either all-electrically powered or partially electrically powered. The rolling resistance can be determined based on motor signaling from one or more motor sensors that sense motor characteristics (e.g., drawn current) from one or more electric motors that drive the machine. The weight of the machine can be determined using the determined rolling resistance. Weight information can be output for display on a display and/or for storing in computer-readable storage onboard and/or offboard the machine.

Embodiments of the present invention are directed to a new and improved system and method for determining a weight rating for a surface road transporter by using a computing system and digital camera to identify various attributes of the transporter and then, based on those attributes, to determine a maximum allowable load limit for that transporter in a given jurisdiction. In addition, embodiments of the present invention may include a digital optical device and related software configured to scan and decipher a QR code printed on an “overweight” permit issued by a local jurisdiction, where the overweight permit authorizes a specific transporter to carry a load that exceeds its normal gross allowable weight by a specified amount or percentage. Embodiments of the present invention may incorporate the specified overage amount or percentage in its determination of the gross allowable weight rating for that transporter.

An article transport facility includes a transport conveyor (34) and a weighing device (24), which includes a support portion (28) for supporting a container (C1) and a measuring portion (30) configured to measure a weight of the container (C1) supported by the support portion (28). The article transport facility is configured to perform a state change between a withdrawn state in which the support portion (28) is withdrawn downward relative to a transport surface (34A) and a protruding state in which the support portion (28) protrudes upward relative to the transport surface (34A) by moving the support portion (28) and the transport conveyor (34) relative to each other in a vertical direction (Z). A support surface (28A) of the support portion (28) is inclined such that one corner portion (8A) of multiple corner portions (8) located at corners of the container (C1) is lower than the other corner portions (8).
