Wheel loader weighing

Fast and secure data transfer from the wheel loader to the end customer

A lot of walking back and forth, numerous supporting documents and entrenched organizational processes.

All that belongs to the past now at Rheinische Baustoffwerke. With the system solution now in use, a mountain of paperwork and superfluous analog data flow that were part of extraction are now eliminated. Thanks to the digital process, weighing data can no longer be lost or transferred to the wrong electronic data processing system.

Add to that increased convenience for customers and employees. The Erkelenz-based company now concentrates solely on an efficient extraction process without superfluous wait times while the PFREUNDT Web Portal takes care of the administrative overhead.

The advantages of the new wheel loader weighing system:

  • Very low risk of accident because the truck driver does not get onto the wheel loader
  • Faster data transmission with the latest technology
  • Headquarters has immediate access to all data
  • The MFT terminal prints the delivery slip in DIN A 4 format and with more data than on the weighing slips
  • Quality symbol can be printed, also visually appealing design thanks to modern laser printers
  • QR code is printed, which the end customer can use to read in complete data for viewing and further digital processing

Old and new process

Extraction: Weighing with the wheel loader scale

The old process on site:

  1. Check-in: Truck driver drives up to the material, where the wheel loader is ready for loading.
  2. Transmission of master data: The truck drivers leaves his cab if necessary and communicates his master data to the driver of the wheel loader.
  3. Loading: The wheel loader selects the data on the scale and loading is carried out.
  4. Weighing data acquisition: The driver of the wheel loader creates a weighing note, the truck driver gets out again and signs it. 
  5. Data transfer: The truck driver keeps the printouts for the unloading point. and the driver of the wheel loader receives a carbon copy.
  6. Data transmission I: The truck driver delivers the printouts to the unloading location. They are collected and archived as legal-for-trade records.
  7. Data transmission II: In the office the master data is transferred to a system and made available daily by the electronic data processing system.

The new, innovative process with PFREUNDT system solution:

  1. Check-in: The truck driver receives an RFID card one time for saving the weighing data.
  2. Loading/weighing data acquisition: A wheel loader with the PFREUNDT WK60 weighing system loads and records weighing data.
  3. Saving the weighing data: The weighing data is read by the RFID write / read device on the wheel loader and saved on the RFID card.
  4. SB terminal: After loading and before leaving, the RFID card is read at the SB terminal.
  5. Weighing data approval: The driver signs the weighing data and prints the delivery slip.


Vehicle scale weighing

More security and less overhead for employees

Cards instead of notebooks – all the necessary data at RBS is now saved on an RFID chip when loading by wheel loader. Thanks to this smart process, the truck driver does not need to leave the cab until after the loading process. All other processes are digital. This prevents wait times and optimizes processes.

With the new MFT terminal customers can view and approve the loading data. All recorded weighing data is sent as PDF files and raw data files to the office with a copy also going to headquarters, where data is automatically imported into the data processing system.

The advantages of the new process:

  • Headquarters has access to data, which is available quickly
  • Data is transferred to the SAP system where it is stored centrally
  • The truck driver does not leave his vehicle during loading and weighing, which reduces possible hazards
  • He only leaves his cab in the exit area, at the multifunction terminal (MFT) to generate the delivery slip
  • The delivery slip is generated fully automatically and does not require an employee
  • Delivery slip is generated in DIN A 4 format and contains more information
  • Quality seal and QR code are also available for this
  • Mixed operation is possible with silo loading, wheel loader loading and vehicle scale and can also be used for a limited time during peak times

Old and new process

Extraction: Weighing using vehicle scales with wheel loader and silo

The old process on site:

  1.  Check-in/loading: After the truck drives up it is filled by a wheel loader or silo loading, then it drives onto the vehicle scale.
  2. Weighing data acquisition: The RBS employee enters all the master data manually – customer, construction site, license plate, forwarding agent, article, supplier and other data may be needed. Then the truck is weighed. With the saved tare weight and the determined gross weight, the net weight of the load can now be determined. But the saved tare weight does not reflect the actual empty weight of the vehicle and therefore leads to a deviation in the net weight (the weight of the dispensed material). If the desired amount of material has not been loaded, the driver has to go back to the loading point.
  3. Saving the weighing data I: Now the driver signs on the signature pad and receives the printed delivery slip from the RBS employee.
  4. Saving the weighing data II: For the office, the scale PC exchanges its master data and weighing data at periodic intervals with the server in administration.

The new, innovative process with PFREUNDT system solution:

  1. Check-in/weighing data acquisition: The truck is weighed by the PFREUNDT vehicle scale. The truck driver receives an RFID card with the saved weighing data.
  2. Loading: Depending on the requirement, a wheel loader or a silo system loads the truck.
  3. Weighing data acquisition: Before leaving, the loaded truck is weighed again and the weighing data is saved on the RFID card.
  4. Weighing data approval: The RFID card is read at the SB terminal. The driver signs the weighing data and prints the delivery slip.
  5. PFREUNDT Web Portal: Transfer of weighing data in real time to the SAP system for additional processing. No manual recording is necessary.


Weighing during tipping

Correct processes at maximum speed

Development processes frequently involve extensive administrative overhead.

No more for Rheinische Baustoffwerke in Hürth: Thanks to smart allocation of initial deliveries and an express line for regular customers, long wait times are prevented. All necessary documents such as approvals are submitted, data is saved on the RBS card and is accessed when the truck arrives by a reader. The system determines the weights and after they have been confirmed by the driver they are automatically written to the RBS card.

The truck driver confirms his delivery on a display positioned at the height of the cab. The dumping location appears directly on the display and is written to the RBS loading card. The delivery point is saved digitally by GPS coordinates so it can be tracked permanently. After unloading, the truck drives onto the ground scale and parks close to the new MFT terminal. The driver inserts his card and is able to view all the recorded data on a touchscreen and confirm the data at the end with his signature.

The data recorded in the process is sent to the office by a service. PDF files and raw data files, including copies of all generated weighing data, are sent to headquarters, where they are automatically loaded into the data processing system.

Overview of the advantages of the new system solution:

  • Quickly available data
  • Reduces workload for employees at the scale because typical work processes are eliminated
  • Visually appealing delivery slips with more information and in practical DIN A 4 format (8.3" x 11.7")
  • Sampling cannot be forgotten because the system requests it
  • Shorter wait times thanks to express line
  • More throughput
  • GPS data of dumping locations allows for extremely accurate documentation
  • The most modern weighing system anywhere in Europe thanks to innovative technology with a view towards sustainability and optimum processes


Old and new process

Disposal: Weighing with vehicle scales

The old process on site:

  1. Check-in: Previously a truck driver arriving at the RBS area for receiving excavated soil and foundry sand on the Hürth plant grounds first went to the office container.
  2. Weighing data and recording material: After he has parked his truck on the scale, the driver hands in his documents in the container for the initial delivery. For follow-up deliveries, RBS personnel checks the already existing documents and determines the gross weight by weighing with a fixed tare value.
  3. Sampling: Samples are taken sporadically for all deliveries. The driver leaves a digital signature and receives the delivery slip in return.
  4. Unloading: Then the truck driver is informed of the dumping location and he drives up for unloading.
  5. Transmission of data: The master data and weighing data arrives in the office with the next cyclic exchange.

The new, innovative process with PFREUNDT system solution:

  1. Check-in/weighing data acquisition: When the loaded truck enters it is weighed and the load is checked. The data is saved on an RFID card.
  2. Processing on site: The data on the RFID card is accessed by a mobile app and viewed, then the unloading place is logged by GPS data.
  3. Unloading: The load is unloaded at the assigned position on site.
  4. Weighing data acquisition: After unloading the empty vehicle is weighed and the weighing data is saved on the RFID card.
  5. Weighing data approval: Before leaving the RFID card is read in the SB terminal, then the driver signs the weighing data and prints the delivery slip.
