When choosing a weighbridge there are a number of important considerations to make to ensure all of your needs are met. Initially, these are the two most important:
There are two types of weighing methods that can be performed using a weighbridge. These are direct and end-and-end. Direct weighing is performed by driving the truck completely onto the scale and taking a measurement. This is the most accurate type of weighing and should be used whenever possible. End-to-end weighing can be performed if a truck does not fit on the weighbridge. However, this type of weighing must be approved by the National Measurement Institute (NMI) and should not be used as the main form of weight gathering.
A weighbridge can cost between $9,000 - $100,000. The price of a weighbridge depends on a range of contributing factors. These include the material, the weight capacity, the size, the accuracy, the add ons and the warranty provided by the manufacturer. A top of the line weighbridge may be made of galvanised steel that is rust proof, has a maximum capacity of 200 tonnes, an accuracy of 10kgs, with boom gates, a security camera and a 5 year warranty.
As a weighbridge is used for transacting goods and transporting commercial material it must be approved by a servicing licensee appointed by the National Measurement Institute (NMI). It is important to note that a servicing licensee must also verify the weighbridge after each repair or adjustment to ensure it meets industry standards.
A weighbridge is designed to provide accurate weight measurements and requires regular upkeep and maintenance to function properly. The operator should perform daily checks to ensure adequate weighing conditions that do not affect the zero balance of the scale. This includes a visual inspection for loose, rusted or broken components and that there is no foreign matter such as water or debris under the platform. The surface of the platform should also be free of debris and may require regular cleaning to remove rocks, sand and mud.
Weighbridges come in a range of specifications and are designed to meet the needs of commercial vehicles. Here is a variety of capacities, dimensions and accuracy range metrics from some available models.
|Maximum capacity (kg)||Dimensions (m)||Accuracy (+/-kg)|
|1,000||2.5m x 4m||5|
