Abstract
In a wheel cleaner for the cleaning of truck wheels solely by centrifugal action, a weigh beam is incorporated whereby the individual axle loadings and the total weight of the truck can be determined. At the center of a wheel cleaner frame that is set into the ground, pairs of transverse horizontal rollers are provided on which the truck wheels can be spun to throw off mud, stones etc. At the end of the frame a transverse weigh beam, having its top surface substantially at the same level as the tops of the rollers and the frame members, is carried for limited downward travel on end suspension mountings each incorporating a load cell. The load cells give analogue electrical signals that are converted to digital form and processed to derive individual axle loadings and vehicle payload.
