A complete set of Buildgram electronic truck scale consists of five standard core components plus customizable auxiliary modules, with fully modular design for easy transportation, assembly and maintenance worldwide.

2.1 Scale Body Bearing Platform

The weighing deck of Buildgram weighbridge is integrally welded with thickened U-shaped steel and channel steel, supplied in integral or split modular styles. The surface adopts thickened anti-slip steel plate, treated by sand blasting rust removal, epoxy anti-corrosion coating or hot-dip galvanizing to resist long-term vehicle impact, abrasion and outdoor rust. Multiple standard platform dimensions and non-custom sizes are supported to match different truck lengths.

2.2 High Precision Weighing Sensor

Buildgram equips each truck scale with high-precision strain load cells, divided into analog and digital versions. Digital load cells reach IP67 waterproof & dustproof grade, featuring strong anti-electromagnetic interference, real-time self-fault diagnosis and anti-manual tampering function, effectively eliminating weighing deviation caused by complex outdoor environments.

2.4 Waterproof Junction Box

Standard supporting sealed waterproof junction box for all Buildgram weighbridge models. It collects multi-channel sensor signals and balances signal differences to guarantee consistent weighing accuracy. Digital junction box can separately monitor the operation status of each single load cell, greatly simplifying daily inspection and fault troubleshooting.

2.5 Optional Auxiliary Supporting System

Customers can match multiple functional accessories for Buildgram electronic truck scale according to site demands: weighing approach slopes, limit buffer stoppers, lightning protection modules, license plate recognition cameras, automatic barrier gates, explosion-proof assemblies and full unattended weighing software packages for automated unmanned weighing yards.

3. Buildgram Weighbridge Classification

3.1 Classified by Installation Method

• Shallow Foundation Buildgram Truck Scale: Embedded ground mounting, deck flush with road surface, compact footprint, suitable for high-frequency weighing sites like logistics parks.
• Foundation-Free Build Weighbridge: Direct ground placement with matching approach slopes, low construction cost, easy drainage and convenient maintenance, the most popular choice for global small and medium factories.

3.2 Classified by Sensor Type

• Analog Buildgram Weighbridge: Mature stable technology, cost-effective for regular light-to-medium load industrial scenarios.
• Digital Buildgram Electronic Truck Scale: Superior anti-interference, anti-cheating and high precision, equipped with remote fault diagnosis, preferred for mining, chemical and high-standard trade settlement yards.

3.3 Classified by Load Range & Size

Standard weighing capacity of Buildgram weighbridge: 30t, 60t, 80t, 100t, 120t, 150t, 200 tons.Standard platform dimensions: 3m×6m, 3m×9m, 3m×12m, 3.4m×18m.Custom non-standard length, width and tonnage are acceptable. Special customized types include explosion-proof weighbridge, mobile portable truck scale and axle load scale.

4. Working Principle of Buildgram Electronic Truck Scale

When a loaded truck drives steadily onto the Buildgram weighbridge platform, the full vehicle and cargo weight transfers to each load cell and triggers tiny elastic deformation of the sensor elastomer. The built-in strain gauge changes resistance value, and the Wheatstone bridge converts physical deformation into standard electrical signals.

All signals converge to the waterproof junction box for unified calibration, then transmit to the intelligent weighing instrument. The instrument amplifies, calculates and completes analog-digital conversion to output accurate total weight, tare weight and net weight data, finishing automatic vehicle weighing and recording in one cycle.
