The maindraw back to using the Above Ground Weighbridges design is that it usually requires more available space than any other type of Weighbridges. The “total installed length” of a short 18 metre Weighbridge usually exceeds 30 metres and in some cases, much more, depending on site conditions where the weighbridge is being installed.
The Above Ground Weighbridges has its concrete foundations at ground level, then the Weighbridge deck is raised to allow fitting of the Weighbridge loadcells and loadcell mounting hardware. Level approaches and departures are required at both ends of the Weighbridge and then incline ramps are needed to allow vehicular access to the weighbridge deck.
The length and height of the Weighbridge ramps are largely governed by the physical dimensions of the Weighbridge loadcells being used. It is important to select a brand of Weighbridge loadcell that is as short as possible in order to minimise the construction costs of the Weighbridge ramps. Also take into account the height of the loadcell mounting hardware as the actual “installed height” for different brands of Weighbridge loadcells varies considerably.
For accurate weighings, the trucks/trailers should fit completely onto the Weighbridge deck, but if this isn’t possible, then Govenrment regulations stipulate the required length of level approaches and departures at each end of the Weighbridge deck.
This total installed length of the Weighbridge can further impact harshly on available space if the truck also needs to turn onto or off the Weighbridge as the truck must be in a straight line entering the Weighbridge and cannot begin turn off until it has fully cleared the Weighbridge’s departure ramp.
Before considering and budgeting for the Above Ground Weighbridges, carefully consider whether there is room for the “total installed length” of the Weighbridge plus turning space for trucks as required. The overall legal lengths of trucks has steadily increased over time and may continue to do so which could impact further on Weighbridges installed into limited spaces.
