Weighbridges - An Important Tool for Weight Measurement

A weighbridge is a large instrument that measures the weight of heavy vehicles such as trucks and freight. It comprises a platform or deck according to the vehicle’s position. Furthermore, engineers position load cells underneath the deck to measure the applied weight. However, technicians convert the load cell readings into mass units such as kilograms or pounds.

Weighbridges are heavy-duty weighing systems that can withstand rough usage and heavy loads. Additionally, they come in different sizes, capacities, and designs to suit various industry requirements. Weighbridges provide vital weight measurements for trade, transport, logistics, and other sectors.

Types of Weighbridges

You can find several types of weighbridges designed for different applications:

• Pit-type weighbridge - The platform is installed at ground level in a pit. And then, vehicles drive over the hole for weighing.

• Flatbed weighbridge - The entire system is installed above ground without a pit. Ramps additionally provide access to the weighbridge deck.

• Railway weighbridge - Used to weigh train wagons. In addition, the rails rest on load cells to determine the weight.

• On-board weighbridge - Compact weighing systems installed on trucks to measure axle weights.

Digital weighbridges

Digital weighbridges utilize electronic sensors, signal conditioning, and computerised weighing systems. Furthermore, they deliver superior accuracy compared to old-fashioned mechanical weighbridges.

Critical advantages of digital weighbridges:

• Highly accurate load cell technology

• Quick and easy weighing process

• Digital display of weight values

• Data integration options for computers

• Built-in calibration and diagnostic functions

• Minimal maintenance requirements

In addition, advanced digital weighbridges feature automation, data analysis, and cloud connectivity. They can also be controlled remotely via web and mobile apps.

Weighbridge manufacturers

Weighbridge manufacturers design, build, and install weighbridges. They offer complete weighing solutions to meet the needs of diverse industries.

When selecting a weighbridge manufacturer, some essential factors to consider are:

• Experience and reputation in building weighbridges

• Range of weighbridge models and capacities offered

• Use of high-precision load cells and electronics

• Custom engineering services are available

• Quality control and testing procedures

• Installation, calibration, and maintenance support

• Local presence and service capabilities

• Compliance with weighing regulations and standards

• Pricing and value for investment

Leading weighbridge manufacturers also utilize the latest technology to engineer robust systems with long service life and low maintenance needs.

Applications of Weighbridges

Significant applications of weighbridges include:

1. Logistics - Weighing trucks for shipping and delivery purposes. They are used at warehouses, distribution centres, and ports.

2. Mining - Measure payload weight at mining sites. In addition, this tracks the quantity of materials mined or transported.

3. Agriculture - Weigh harvests, livestock, and agricultural produce at farms and processing plants.

4. Manufacturing - Monitor assembly line input and output materials in factories.

5. Recycling - Determine weights for scrap, waste, and recycling streams at transfer stations.

6. Research - Used in laboratories to measure the mass of samples for R&D activities.

7. Trade - Accounting for goods exchanged by weight-based transactions.

Weighbridges play an indispensable role across many sectors of the economy. They also enable efficiency, standardization, and optimization in weighing processes.
