This article reviews the options for avoiding axle overloads on lorries; the problem is harder to solve than is often supposed. The greater the load tolerance of a vehicle (the difference between the sum of its plated axle weights and its gross weight), the less the risk of an individual axle overload, but tolerance on some configurations and specifications is tiny. Some operations are more liable to axle overload than others; for example, bulk cargoes can vary in weight according to whether they are wet or dry. Many systems have audible alarms that sound when the payload is within 500kg of its legal limit. The introduction of electronic load cells has made on-board weighing more accurate, but such weighing is sometimes the most costly option. The UK Government's Authorised Weights Regulation, to be published soon, will again focus attention on axle and gross weights. On-board systems using Class 3 weigh cells, which meet the criteria of the new regulations, are used on the latest bin-weighing systems made by PM On-Board and Red Forge, which use dynamic weighing of trade waste bins as they are tipped into the waste body. Both systems use sophisticated on-board computing and communication equipment. Maywood's Tiploader combines load cells at the body hinge and hydraulic pressure sensing in the ram.
