Axle pressure scales are special types of scales that are used to measure the pressure that occurs on individual vehicle axles. They are particularly important in the heavy-duty industry, such as trucks, buses, trailers, etc., as they allow the vehicle to be accurately weighed to ensure that the maximum permissible axle weight is not exceeded. In addition, axle pressure scales can also be used to test and measure the safety of roads and bridges, to determine how much load they can withstand without damage or deterioration.
