Weight Scale Pioneers in Pakistan. We Weigh The Pakistan.

Weighing Bridge

Truck scales (US) or weigh bridges (non-US) are large scales, usually mounted permanently on a concrete foundation, that are used to weigh entire vehicles and their contents. By weighing the vehicle both empty and when loaded, the load carried by the vehicle can be calculated. The key component that uses a weighbridge in order to make the weigh measurement is load cells.

The weight bridge model offered to clients comes with high internal resolution and bright seven segment LED display, which makes it easy to operate. They are designed for rugged outdoor applications under extreme weather conditions. The system's user-friendly software is compatible with WINDOWS operating system and the load indicator and associated electronics can be conveniently located within a distance of 20 meters from the platform.

It is completely maintenance free, more economical & trouble free as compared steel weighbridge. Save transport cost as it is constructed at the site.

Types of Weigh Bridges

  1. Electronic (deep pit type)
  2. Electronic (shallow pit)
  3. Electronic (pitless type)
  4. Digital (deep pit type)
  5. Digital (shallow pit)
  6. Digital (pitless type)
  7. Mechanical weighbridge
  8. Mechanical (digital type)
  9. Electro-mechanical
  10. Portable weigh bridge
  11. Axle scales
  12. Portable ramp end scales

Truck scales can be surface mounted with a ramp leading up a short distance and the weighing equipment underneath or they can be pit mounted with the weighing equipment and platform in a pit so that the weighing surface is level with the road. They are typically built from steel or concrete and by nature are extremely robust.
In earlier versions the bridge is installed over a rectangular pit that contains levers that ultimately connect to a balance mechanism. The most complex portion of this type is the arrangement of levers underneath the weigh bridge since the response of the scale must be independent of the distribution of the load. Modern devices use multiple load cells that connect to an electronic equipment to totalize the sensor inputs. In either type of semi-permanent scale the weight readings are typically recorded in a nearby hut or office.
Many weighbridges are now linked to a personal computer which runs truck scale software capable of printing tickets and providing reporting features.
