PFREUNDT GmbH (Germany) - Rheinische Baustoffwerke (RBS) has chosen an automated weighing solution designed by PFREUNDT and equipped with smart SysTec weighing indicators.

Rheinische Baustoffwerke (RBS) is a large producer of sand, gravel and building materials with disposal capacities.

In Hürth Ville, Germany, RBS operates a modern landfi ll for mineral waste. To unlock effi ciency gains in truck scales at the disposal site, RBS has chosen an automated weighing solution designed by PFREUNDT and equipped with smart SysTec weighing indicators.

PFREUNDT considered especially RBS‘ operating requirements during development.

The key facts

• Fully automated weighing process
• 2 truck scales at the entrance with driver self-service terminals and 2 vehicle scales at the exit
• Weighing data recording on RFID cards
• Logging of the unloading position (storage of GPS data)
• Legally compliant material sampling processes

Customer benefits:

• Automated PFREUNDT system solution saves time and resources - high productivity, lower operating costs
• More throughput: No more queues at the entrance, as trucks can be quickly dispatched by means of digital truck scales with self-service terminal
• Precise accounting of weighed and delivered materials
• Robust SysTec weighing indicators for outdoor use
• Complete digital documentation of the disposal process on RFID cards
• Fast processing of the data by ERP connection
• High reliability due to self-suffi cient system: the solution is designed in such a way that power supply is suffi cient in case of temporary failures of the online connection

Weighing 4.0 - PFREUNDT´s system solution:

Automation is a key lever at RBS to become faster and more efficient. For this reason, RBS relies on digital weighing processes. When it comes to designing and implementing the weighing technology solution for the landfill in Hürth Ville, RBS opts for a PFREUNDT system solution and the smart SysTec weighing indicators.

“We developed the system solution specifically for RBS‘s operational requirements. It covers all processes from the completely automated weighing process, including initial and secondary weighing of the trucks, to material sample documentation during the
dumping processes and commercial procedures at the exit,“ says Mark Terbrack, application consultant and specialist for system solutions at PFREUNDT.  “PFREUNDT has always had a high demand for innovation and quality - this is also appreciated by our customer RBS. The weighing electronics must meet this demand. That‘s why we rely on SysTec weighing indicators and terminals: robust, digital, W&M approved and the systems have a convincing operating concept.“

Check-in scales:

Both truck scales operate with an automatic check-in. The truck drivers, who already possess RFID cards from RBS with recorded master data for the loaded material, can simply hold the card up to the reader at the self-service terminal. There is no need to get out of the vehicle, the processes run quickly.

The self-service terminal displays the unloading point, all order-relevant data, and also the material to be dumped. The truck driver actively confirms the data at the terminal. At check-in, an RBS employee can use a camera to carry out a visual inspection of the loaded material and, if there is any suspicion, arrange for unscheduled sampling of the load. For new customers not yet registered, an RBS employee issues a new card. The truck scales are equipped with a traffic light system. If the system is not ready for use, this is signaled by the flashing red light. When the scale is zeroed, the traffic light is green and the truck can drive onto the scale. After weighing, the truck starts to the designated unloading point.

Dumping and material samples:

The self-service terminal displays the unloading point, all order-relevant data, and also the material to be dumped. The truck driver actively confirms the data at the terminal. At check-in, an RBS employee can use a camera to carry out a visual inspection of the loaded material and, if there is any suspicion, arrange for unscheduled sampling of the load. For new customers not yet registered, an RBS employee issues a new card. The truck scales are equipped with a traffic light system. If the system is not ready for use, this is signaled by the flashing red light. When the scale is zeroed, the traffic light is green and the truck can drive onto the scale. After weighing, the truck starts to the designated unloading point.

Check-out and weighing data approval:

Finally, the weight of the unloaded truck is recorded at the outgoing scales. The driver signs the weighing data approval and receives the delivery note.
