Apart from customer support in project planning GRABAND pays special attention to correct imple­men­ta­tion of required specif­ca­tions when designing new systems.

At the same time GRABAND can compre­hen­si­vely be integrated in indivi­dual project teams of indus­trial partners and is therefore able to meet demands of covering produc­tion peaks at any time.

This especi­ally accounts for assuring functional safety in the fields of interlo­cking over (rail) vehicles and up to robotics.

GRABAND offers competent and economic solutions as well as custo­mized hardware made for your special needs – we serve you in both: using new techno­logy as well as moder­ni­sing existing systems.

Our Services

Complex projects require swift and extensive systemic analyses. Our team independently creates solutions to technical and holistic questions.

Principle studies

If you wish to review your current strate­gies in order to deal more effec­tively with future tasks, you need sugges­tions for sustainable and economic overall solutions as well as funda­men­tals for invest­ment decisions. We ensure with our experi­ence that you as our customer can expect an overall systemic overview, a qualified survey of variants, as well as compre­hen­sible and indepen­dent evalua­tions of various concepts from us. The principle studies include among others the technical compa­rison of different systems, an evalua­tion of perfor­mance potential, feasi­bi­lity studies and market analyses. We focus on train protec­tion and signaling systems, opera­tions control and vehicle techno­logy.

Systems techno­logy

When complex systems are newly imple­mented or existing systems require adjus­t­ments we often face a tight deadline and a tough cost projec­tion going along with a scarcity of own resources. If you want to funda­men­tally analyze your tasks and first would have to specify GRABAND is the right partner. Thanks to numerous successfully accom­plished projects you can rely on our systems experts who know their systems inside out. Within this framework you can for instance expect an interface descrip­tion or speci­fi­ca­tions for detailed develo­p­ment. You are only right to expect that we will find all the locks and keys of your existing systems and compon­ents just as well as your develo­p­ment environ­ment. At the same time we guarantee saving your know-how as well as competent and flexible project manage­ment. Our portfolio among others includes basic evalua­tion, defini­tion of technical tasks as well as drafting perfor­mance and requi­re­ment speci­fi­ca­tions, concep­tion, analysis and speci­fi­ca­tions. We bring along the necessary experi­ence in main line and branch line rail, in metro and tram traffic just as well as in BOStrab (German Ordinance on the Construc­tion and Operation of Rail Systems for Light-Rail Transit) requi­re­ments.

Order develo­p­ment

If you are challenged by having to utilize new hardware in your systems or projects, seek to modernize existing hardware, or initiate new adaption hardware – then GRABAND should be your first choice. Get competent and economic solutions just as well as custo­mized hardware.

We will find innova­tive and sustainable solutions with plenty of know-how from a number of various develo­p­ments for you. Here being experi­enced is a good asset – this is thanks to our own products – which, are still in use today. Our portfolio covers every­thing from hardware speci­fi­ca­tions, circuit diagram design, choice of construc­tion elements, board layout to imple­men­ta­tion and testing. We can offer you entire small-scale series, if desired, including safety verifi­ca­tion. Our range of experi­ence goes from safety-related appli­ca­tions and process control enginee­ring all the way to power connec­tions. We are also delighted to develop analog techno­logy, relay techno­logy, digital techno­logy, computer techno­logy, bus techno­logy or trans­mis­sion techno­logy for you.


Also reliably developed and regularly maintained compon­ents and systems at some time are subject to the process of aging and wear and tear. GRABAND is always the right partner for you when it comes up to trouble­shoo­ting, fault analysis and mainten­ance work of your systems. We also enjoy tackling obsole­s­cence. We are also familiar with reverse enginee­ring. Repairs will be carried out swiftly and effici­ently and therefore econo­mic­ally. Certainly, we test your repaired systems and compon­ents before sending them.
