Product Brief of Pit-Mounted Truck Scale

The pit-mounted truck scale, also known as pit scale or flush weighbridge, is a type of weighing equipment installed below ground level, with its scale surface perfectly flush with the ground.
Here is the detailed introduction:
•Structure and Working Principle
The pit-mounted truck scale is mainly composed of three key components: scale platform, load cells, and weighing indicator. The scale platform bears the weight of goods and transmits the force to the load cells. The load cells convert the received force into electrical signals, which are then processed by the weighing indicator to display the weight value. When goods or vehicles drive onto the scale platform, the elastomer of the load cells deforms under the action of gravity, generating corresponding electrical signals. These signals are further converted into digital signals and the weight of the goods is finally displayed on the weighing indicator.

•Features and Advantages 
It boasts a neat and aesthetic appearance as it does not occupy extra above-ground space, keeping the overall site look tidy. It is an ideal space-saving solution for venues with limited area. Meanwhile, vehicles can drive directly onto and off the scale without the need for approach ramps, which significantly improves weighing efficiency. In addition, the underground installation design endows it with excellent waterproof and corrosion-resistant performance, making it suitable for use in humid, waterlogged environments, as well as occasions requiring explosion-proof and anti-corrosion properties.
•Application Scenarios 
It is applicable to scenarios with limited space that pursue neat appearance and require long-term stable operation, such as fixed weighing stations, logistics centers, commercial hubs, etc.
•Maintenance and Upkeep 
Since the scale body is located underground, the ventilation condition is relatively poor, which increases the difficulty of maintenance and upkeep. Special attention should be paid to drainage and moisture-proofing work. Regular inspection and cleaning are required, and periodic calibration and maintenance should be carried out in accordance with the manufacturer's recommendations to ensure the accuracy and stability of weighing results.

FAQ

How is the accuracy of the truck scale ensured?

Based on years of project delivery experience, WTWS has summarized 33 factors that affect the accuracy of truck scales. You can contact the staff on the page to obtain this information.

Is the use of the truck scale greatly affected by the environment?

Generally, the installation location of the truck scale should avoid areas with strong winds and strong magnetic fields. It works well in normal outdoor operating environments.

Can the truck scale be connected to software systems?

Absolutely. WTWS has its own R&D team, and the weighing software can seamlessly integrate with various order management software, warehouse software, financial software, and quality inspection software, facilitating the integrated management of enterprises.

Can the truck scale weigh different types of vehicles?

Yes. WTWS can provide weighbridge sizes according to the specific on-site usage conditions, which can weigh various container trucks, semi-trailers, trucks, mining trucks, light trucks, etc.

Is a concrete foundation mandatory for the truck scale?

A good concrete foundation can ensure the long-term use and accuracy of the truck scale. However, if the on-site conditions are good, a concrete foundation is not required—you can use a weighbridge with a built-in steel foundation and approach ramps.
