Quarry & concrete
Quarries, Concrete and Cement plants

Quarries often work with other companies, such as concrete and cement plants, which order their production. To manage the ordering process in one place, on-site Scale Expert programs are used to to carry out the weighing process at the local weighing points and the online Scale Expert Cloud system is used as the main data center.

Arriving vehicle’s registration plate can be registered by client/contractor? in advance online in order to speed up the production or material acquiring process. When the vehicle arrives, the driver types in his vehicle’s registration plate in the driver terminal and the system uses registration data to fill-in weighing data, print loading sheet and assist the driver.

In such cases, where the driver does not have the advance registration, the system can be configured to request all the required information (name, registration plate, company, product e.t.c.) to be entered manually via the driver terminal.

The quarry loaders are equipped with tablet PCs which communicate to the weighing system via GSM Internet and show the incoming vehicle’s registration number and cargo type that has to be loaded.

If there is no weighbridge in the quarry or it is not cost-effective, the loader can be equipped with onboard scales. The loader driver can receive orders from Scale Expert Cloud directly to the tablet PC. All weighing results are synchronized online and can be used to generate reports, analyze and export to accounting systems. Clients/contractors? can also view their order execution status and fixed weights.


Grain acquisition process can be started from the vehicle’s arrival at the elevator:

At first, the driver passes through the registration point and gets an RFID card for unloading, then a logistic’s operator calls the next vehicle using scoreboard where a vehicle registration plate is displayed. Afterwards, the grain sample is taken from the vehicle for a laboratory inspection. When the sampling is done, the vehicle goes to the waiting area and after the laboratory approval, it is called via the next scoreboard.

The vehicle arrives on the weight bridge to fix bruto weight. When the driver puts his RFID card to the card reader at the registration point, the vehicle weighing process is carried out and the driver sees his vehicle’s fixed weight. A green arrow appears on the scoreboard, which indicates that a vehicle can now drive off the weight bridge.

After the weighing process, the vehicle moves to the waiting area. At the same time, the logistic’s operator can view laboratory tested vehicle’s grain class and unloading storage number, where the grain have to be placed. When the discharging pit is prepared, the vehicle is called to the designated grain storage via the scoreboard.

When the vehicle’s number appear on the scoreboard, the driver moves for the unloading. After the unloading, the vehicle goes to the next weight bridge and driver repeats the weighing process.

Finally, the driver returns the RFID card to the operator and receives an invoice or other documents at the logistics department which has the full information of the vehicle’s cargo. The data is then exported to a local accounting system.


Most biofuel companies have more than one energy plant where biofuel is used. Usually, the received biofuel must be analyzed in the laboratory to define its physical parameters like humidity and efficiency.

Each energy plant equipped with a weight bridge and Scale Expert program can be connected to the Scale Expert Cloud system in order to synchronize data between local programs and main logistic department. Logistic department fills in the purchasing information in the Scale Expert Cloud system and sets agreement defined  Boiler House to receive the biofuel. All Boiler Houses‘ weighbridge programs (ScaleExpert) receive information from the Logistic department. In such situations where all arriving car number plates are known, the logistic department or local operators can register them and set agreement in the system.

On the arrival of the vehicle to the Boiler House weighbridge, cameras recognize numberplate and make weighing automatically. The driver gets a ticket with vehicle weight and agreement information from the ticket printer on the weighbridge.

After weighing the full vehicle, the operator gets a barcode label and sticks it on a biofuel sample. Next, this sample goes to the laboratory for quality analysis.

Our laboratory module organizes laboratory assistant work with the received samples. The assistant uses a barcode reader and scales only to fix all of the measurement methodic steps. The codes are scanned from the samples, laboratory plates, scales and ovens in the order shown on the PC terminal. Our module shows step by step commands what has to be done or scanned next. The module can recognize user mistakes and inform the assistant. After all methodic steps are done, measurement results are synchronized with the ScaleExpert Cloud system where cargo measurement values are set. Logistic, laboratory or other department can get reports of each cargo with laboratory measurements and other needed calculations like price correction.
