Weighbridges are the main vehicle weighing equipment in the weighing industry. Out of the other kinds of vehicle weighing equipment, the weighbridge is the largest of them all. A weighbridge, alternately called a truck scale, is a type of vehicle weighing equipment that is used to determine the total weight of a truck or vehicle. Unlike other vehicles weighing equipment like the weighing pads and axle weigh scales which both measure the loads on each wheel axle of a vehicle, the weighbridge measure the vehicle as a whole.
Camaweigh offers weighbridges that consist of five important components; a steel platform, load cells, concrete foundations, scale indicator, and connecting cables. The steel platform is where the vehicle or truck will be stationed for weighing.
Camaweigh has portable and fixed weighbridges. Portable weighbridges, also called pitless truck scales, don't need to be level with the ground. Since it is portable, it can be used almost anywhere it is needed. Setup and movement are easy. Portable weighbridges have ramps on each end to help load and unload vehicles. Without ramps, loading the truck onto the portable weighbridge would be difficult. The concrete foundations of the portable weighbridge are responsible for supporting the load cells which are sandwiched in between it and the steel platform. The concrete foundations should be strong enough to support 40 tons. Load cells are essential for portable weighbridges and vehicle weighing equipment. They read the vehicle's weight.
A portable weighbridge with a defective load cell is useless. Each load cell’s output line is A portable weighbridge with a defective load cell is useless. Each load cell's output line is connected to a junction box or summing box, which adds the results. A scale indicator receives the junction box's output. Camaweigh's load cells are made of alloy steel to withstand heavy loads. The maximum capacity load cell that Camaweigh offers reach up to 40 tons. Load cells convert shear, strain, and compression forces into electrical current. Scale indicators collect and display data.
The weight of the vehicle or truck’s load is determined by first weighing it empty. This will be established as the reference point. When the truck or vehicle is loaded then it will be weighed again on the portable weighbridge. The reference point will then be subtracted from this new weight reading. The difference between the two weights will be the weight of the payload. Calibration tests are very important to conduct on portable weighbridges to ensure that you will get the most accurate reading possible and to find out if you need to adjust anything on the setup. When there is nothing on the portable weighbridge, the reading on the scale indicator should exactly be reading a zero. A repeatability test is a good calibration test to conduct on newly installed weighbridges, portable or not. This calibration test ensures that you will get the same weight result from every single time when the same truck is used under the same kind of condition. If the result of the tests differs each time, then it is best to check the setup and the weighing equipment. It may be that a load cell might be functioning or that maybe the steel platform of the portable weighbridge is not properly in contact with the load cells.
