Safe operation of automated guided vehicle systems

We'll make your automated guided vehicle systems safe. In every way possible!

Where a human shares a workspace with an automated guided vehicle, i.e. a machine, there are particular requirements for safety concepts. Human and machine must be able to operate smoothly and safely within the same environment.

We take a holistic look at your automated guided vehicle system. We get on board as early as the design phase, when the system concept is developed, and provide support for your projects right through to commissioning. That way we ensure that safety and productivity are guaranteed when your automated guided vehicle systems are operated.

Your requirements

Your requirements for automated guided vehicles or vehicle systems

As an operator or manufacturer of automated guided vehicles or vehicle systems (multiple automated guided vehicles), you must comply with the specifications of ISO 3691-4. It defines the requirements of the safety functions and specifies how to validate the vehicles' automated functions.

ISO 3691-4 also specifies the required performance level for the vehicle monitoring functions, various operating modes and the brake controller.

Standard ISO 3691-4 for automated guided vehicle systems and autonomous mobile robots

The standard ISO 3691-4 specifies a clear procedure for achieving safety on an automated guided vehicle system, for both manufacturers and operators. It defines an automated guided vehicle system as a combination of one or more automated guided vehicles or autonomous mobile robots and the plant environment.

The 2020 publication of the standard ISO 3691-4 for automated guided vehicle systems and autonomous mobile robots was a reaction to the rapid development of new technologies in the field of automated vehicles. The ISO standard was long overdue, as its predecessor (EN 1525:1997) had been published 23 years previously. It can now be regarded as the most important international standard for automated guided vehicle systems. In Europe, ISO 3691-4 is supplemented by the standard EN 1175:2020, which refers to specific electrical aspects of self-propelled industrial trucks (including automated guided vehicle systems).

In addition to the international launch of ISO 3691-4, the USA also updated the relevant standards in 2019 and 2020: ANSI/ITSF B56.5:2019 (automated guided vehicle systems) and ANSI/RIA R15.08-1:2020 (autonomous mobile robots).

Automated guided vehicles or vehicle systems in the production hall

Do you use automated guided vehicles or vehicle systems in your production hall or in intralogistics applications? Then you need to ensure that your system is not only designed safely, but is also applied safely and above all productively, taking into account all the spatial and infrastructural conditions.

Our "Safe operation of automated guided vehicle systems" service offers a complete package, right through to the international conformity assessment.

Safe traffic and order management for all participants in intralogistics

For automated guided vehicle systems (AGVS), in cooperation with the expert for material flow automation, NAiSE GmbH, we offer the world's first traffic and order management software, for all participants in intralogistics. Thanks to intelligent sensor infrastructure and integrated, manufacturer-independent communication, the order management software "NAiSE Traffic" analyses the flow of traffic and goods in real-time. The software coordinates and controls traffic involving all parties – whether freely navigating or track-bound, as well as with forklifts.

Benefit from a complete, material flow automation solution: Congestion, bottlenecks, shortages or accidents are avoided. This increases safety and optimises traffic control – for greater transparency, efficiency and productivity.
