An IoT-platform for processing weighing data from construction and loading vehicles


We have created an IoT customer portal in cooperation with PFREUNDT, a leading provider of mobile weighing systems in the world market of the mining, waste-disposal and recycling industries. The platform synchronizes data from construction and loading vehicles in a client-capable web portal that offers a wide range of processing and reporting features.


  • Successful operation since 2013
  • Modern interfaces
  • Complex offline synchronization with conflict resolution
  • Integration of old weighing instruments
  • Client-specific on-premise installations

A central hub for weighing data

PFREUNDT scales can be retrofitted in excavators, wheel loaders, dump trucks, etc., for example, to generate a digital delivery note from the driver's cab when loading bulk material in a gravel pit. The drivers and the scales can generate order data which is synchronized with the cloud platform that we've developed.

PFREUNDT's business customers can use the multi-client capable web platform to analyze the weighing data, process it further and then, for example, export it to accounting.

The complete overview

Software as a Service: As an online platform, the PFREUNDT Web Portal offers maximum data availability from anywhere and for all user devices.

Graphical analysis with customized reports: A graphical analysis of the data is carried out by individualized reports, which are created ad hoc or at regular intervals.

Personalization: All views can be adapted to the specific requirements of individual users and clients.

Data export: In addition to modern automatic interfaces, PDF and Excel exports allow manual processing of the resulting data.

Extreme flexibility: The application provides a common basis for the heterogeneous requirements of different clients - both at the business process level and at the technical level.

Security: High data security is ensured by encrypted data exchange and modern server technology in certified data centers.

An agile project and sustainable cooperation

The initial version of the PFREUNDT Web Portal was developed in an agile process in four two-week iterations. PFREUNDT has worked closely with our team to launch an viable end-to-end solution in minimum time.

With the help of our pilot customers, we were able to expand the platform in a targeted manner through short feedback cycles

Continuous development

The PFREUNDT Web Portal has now been continuously developed and maintained since 2013. Through the everyday use of data, PFREUNDT has created a customer portal which serves as a central hub for customers.

Individual interfaces for scales and ERP systems

We have designed tailor-made interfaces to ensure efficient communication between weighing data and the web portal.

We have also created customizable interfaces for client-specific integration into existing customer ERP landscapes.

A particular challenge during the implementation was preventing conflicts when manipulating data on distributed systems.

Modern machine-to-machine communication

From a technical point of view, we have primarily relied on modern REST-APIs with JSON as the exchange format for the interfaces. But we also overcame the hurdle of fixed legacy interfaces (such as CSV over FTP)) with deviating data models.


PFREUNDT GmbH is one of the world's leading suppliers of mobile weighing systems and is headquartered in Südlohn, in the Münsterland region of Germany. The globally operating company has sold more than 40,000 weighing systems over the last 40 years.
