Gebr. Arweiler: Transforming Multi-Site Maintenance with one Digital System

Gebr. Arweiler, a family-owned company with multiple locations across Saarland and France, has long been known for combining tradition with forward-looking action. With eight plants, a fleet of 26 trucks - including 5 electric vehicles - and a strong commitment to sustainability, the company needed a digital solution to optimize maintenance, asset management, and compliance.

Since implementing CheckProof in July 2024, Gebr. Arweiler has modernized its processes, improved cross-site transparency, and strengthened its long-term vision of operational efficiency, sustainability, and knowledge sharing.

We spoke with the team led by Managing Director Stefan Altmeyer to learn how CheckProof has transformed operations, reduced downtime, and supported employees across multiple locations.

Can you describe how operations were managed before CheckProof was introduced? What challenges did your team face?

Before CheckProof, operations relied heavily on paper-based manuals, printed Excel sheets, and verbal communication.

Altmeyer explains:
“The flow of information was delayed until it reached the Head of Maintenance. Production logs were printed, signed, and redistributed at each quarry. It could take several days for a task or problem to be properly recorded.”

Tracking compliance and production was laborious, and transparency between locations was limited. Coordination between the plants needed improvement, and data was often duplicated or hidden in email inboxes.

“Before CheckProof, tracking maintenance tasks was cumbersome and paper-based before they were entered into a maintenance planner. Now, everything updates in real time and is accessible anytime for everyone.”

How has CheckProof changed the planning and tracking of maintenance tasks at your sites?

All information is now centralized in one system. Excel sheets and printed reports have been replaced with a shared platform where every case can be viewed in real time. This ensures full transparency across the entire team — from machine operators and plant managers to senior management.

CheckProof now serves as a central hub for service tracking, compliance inspections, and asset management. Tasks such as annual fire extinguisher checks, first-aid kit inspections, and lifting gear monitoring are automatically scheduled, managed, and tracked. This ensures both legal compliance and operational safety.

How do the unit cards help in managing parts, replacements, and equipment upkeep?

Unit cards are highly customizable and can include customer-specific details, offering a clear and structured overview of each machine’s key parameters. Depending on the setup, the cards now contain detailed technical specifications for supplier inquiries or new procurement.

“We now even have the option to trigger ordering processes directly through CheckProof,” explains Altmeyer.

How has the CheckProof Planning Tool helped you maintain transparency and control across multiple locations?

The Planning Tool provides a clear overview of all activities and allows central coordination across all sites in Germany and France. Each user can set their preferred language - German or French - ensuring smooth and straightforward collaboration.

Filters allow plant management to view upcoming checks, services, missed inspections, and deviations. Color coding helps maintain an overview. From these, action items and maintenance task lists are automatically created. The system ensures cross-site coordination, streamlines workflows, and improves accountability.

Since implementing CheckProof, can you share KPIs related to time savings, efficiency gains, or reduced downtime?

Digitizing the production log alone has improved both the speed and accuracy of reporting. Instead of entering data multiple times and sending emails back and forth, information is recorded once in CheckProof and is instantly visible to management and administration teams.

Maintenance planning features have helped prevent unexpected breakdowns, as alerts prompt teams to take action before failures occur. This has ensured on-time deliveries and avoided costly downtime.

How does the system support fleet management?

“All documents - including service contracts, intervals, TÜV inspections, and driver checklists - are stored in CheckProof,” Altmeyer explains.

Daily departure checks are not only operationally necessary but also legally required. CheckProof ensures that these checks are completed, logged, and archived automatically.

“This creates real value for us as a company. Our employees can also be confident that everything is properly documented. In case of an accident or damage, we can access all centrally stored data,” adds Altmeyer.

How do digital workflows support sustainability, especially for electric trucks?

The company has been operating electric vehicles for around two years - a key part of its broader strategy to reduce emissions. Through CheckProof’s flexible checklist setup, custom EV checklists can be stored directly with the corresponding vehicle file.

CheckProof also enables the recording of energy consumption in the form of electricity. Beyond manual entries, it can integrate with fuel management software to track consumption and progress toward sustainability KPIs.

“We are currently working with CheckProof on this step,” the team notes.

How has CheckProof changed daily workflows for maintenance teams and logistics coordinators?

Deviations are recorded digitally and become immediately visible. Photos and comments help describe issues clearly, allowing corrective actions to be initiated right away. These deviations automatically generate tasks which, once resolved, are marked as completed.

All records are stored indefinitely, supporting long-term knowledge retention. New employees quickly adapt thanks to the system’s intuitive interface, while digitalized knowledge ensures continuity even as experienced staff retire.

What motivated your company to introduce CheckProof?

Digitalization is clearly the direction the industry is heading towards, and Gebr. Arweiler wanted to prepare for the future. Managing Director Michael Arweiler explains:

“We chose CheckProof because it was developed by industry experts who understand our challenges. The CheckProof team supported us in developing checklists and implementing workflows across our sites.”

How does digitizing maintenance align with your long-term vision?

The company combines tradition with innovation.

“We want to honor our roots as a family-owned business while preparing for the future. Digitization and sustainability are not just trends - they are essential for growth, reliability, and long-term success,” says Michael Arweiler.

What digital or operational goals do you aim to achieve with CheckProof in the next 12–24 months?

The team plans to further optimize maintenance processes, expand predictive maintenance, and integrate additional sustainability metrics. The focus remains on operational efficiency, knowledge retention, and long-term reliability across all sites.

For Gebr. Arweiler, CheckProof helps bridge the company’s long family history and its vision for a modern, sustainable, and efficient future. From coordinating multiple sites and maintaining asset visibility to predictive maintenance and knowledge preservation, CheckProof has become an essential part of their operational success.
