Best Practice : Weigh-in-Motion System
Total weight and weight distribution are two critical factors associated with the logistics of moving personnel and equipment. Oak Ridge’s Weigh-in-Motion system uses portable weighing pads. The technology combines fiber optics and electronics, located within these pads, with weighing algorithms and calibration data. By driving aircraft and ground transportation vehicles over the weighing pads, the system determines the total weight (accurate from 1% to 2%) and the weight distribution by axle or wheel (Figure 2-4).
The Weigh-in-Motion system is available through the Oak Ridge Centers for Manufacturing Technology (ORCMT). Advantages include immediate determination of weight upon passing over the sensors; accurate and reliable technology; lightweight and portable system; modification of established technology; and minimal training for operation.
Weigh-in-motion technology has led to numerous applications such as self-weighing shelves, forklifts, and scrap buckets. In addition, tests currently under way in Knoxville, Tennessee predict the elimination of truck scales on highways. The technology could measure the weight of loads on forklift trucks and eliminate the need for stationary weighing. Fiber optics embedded in strands may enable this technology to weigh materials which are being loaded by crane or other lifting devices. Businesses would become more efficient at handling materials and realize significant cost savings.
