The History of HANNING & KAHL

With our GripMaster® sanding system we guarantee safe braking and acceleration. Pneumatic pumping of coarse-grained quartz sand in wheel-rail-contact ensures best possible friction ratio even in adverse weather conditions.

The distinguishing features of our point machines of the 61/61.1 series are maximum reliability, functionality and economic efficiency. That’s why they are in service all over the world. These point machines can be easily aligned to every operational requirement. In the performance range of the series we offer a version for depots certified SIL 2 in compliance with EN 50129 and a version for line use with maximum safety up to SIL 4 in compliance with EN 50129.

HANNING & KAHL’s point machine H715 has qualified at Austrian Federal Railways (ÖBB) as our trailable point machine has been granted ÖBB approval for service all across the Austrian Federal Railway network. We are also delighted to report that we have gained type approval for our point machine H715 from the Swiss Federal Office for Transport (BAV).

TÜV-Nord has successfully certified HANNING & KAHL GmbH & Co. KG for compliance with the new ISO/TS 22163:2017 standard which has been specially developed for the railway industry. To attain this new standard which sets a new benchmark for the highest quality in the development and production of safety systems for rail transportation worldwide, the East-Westphalian company overhauled its operating processes in the product development, production and life-cycle management of safety systems for rail technology. All these processes were externally audited by TÜV-Nord.

The HZM-IIS measuring device, used to test force on point setting systems, has been approved for use by DB Netz AG. The setting and holding forces of point machines and the setting resistance and holding force of points can be measured accurately, easily and quickly and electronically documented. With the help of the HZM-IIS coupling module, data is exchanged between the HZM and the integrated inspection system (IIS) database system used by DB. With the certificate of quality, the HZM can now be used everywhere in the Deutsche Bahn network.

Today’s complex requirements of Vital Processor Systems as core components in control and safety technology, such as automatic train control, level crossing technology and electronic interlocking, call for safety integrity level (SIL) 4. To fulfil this task we have developed the new HANNING & KAHL Vital Interlocking Processor - HVIP.

Following years of successful supply of brake systems, point machines and controllers to the rapidly growing Chinese market, we set up our own subsidiary in China, the HANNING & KAHL.

Transportation Systems and Braking Technology (Suzhou) Co. Ltd. Major expansion plans for inner-city rail transportation and the speed at which they advance also hold further growth potential for HANNING & KAHL. 

We introduced a totally new intelligent guidance system “GuideLight®”. The LED-based guiding system enables reliable and safe dynamic direction of people flow for better and faster orientation and intelligent evacuation from danger zones. It can be used in buildings, tunnels, workplaces, etc.  

The creative ingenuity of our staff, their ideas and their proactive thinking take us forward. We have received several awards for our culture of trust and an employee suggestion scheme which encourages empowered employees, and we were ranked in first place in the engineering sector for our idea management by the German Institute for Business Management (Deutsche Institut für Betriebswirtschaft DIB).

Well-educated and highly trained staff are the backbone of our company. Our organisation and corporate culture are geared to conveying skills and information and promoting exchange of know-how, all of which are vital for HANNING & KAHL. We have been presented many awards for our achievements including the “Excellent Knowledge Management“ prize from the Society for Knowledge Management e.V. (gfwm).

Only 5 years after product launch, the 5,000 ^th electro-mechanical brake for wind turbines was supplied.

This year, too, VAB introduced the equipment management software TuneQ, making it possible to reduce the costs of the management and upkeep of infrastructure equipment, and rapidly detect and remedy malfunctions. TuneQ is vital for set-up of an “Infrastructure Control Centre“. 

On the occasion of the World Cup in Germany, the Federal President launched an initiative called “Germany – Land of Ideas”. Throughout the country, 365 locations were sought with outstanding creative imaginativeness, a cosmopolitan outlook and social commitment. Applications were open to companies, research institutes, universities, and other corporate / social institutions. HANNING & KAHL was one of the 365 locations in Germany and one of the winners.

UNIFE (Union des Industries Ferroviaires Européennes) and the rail vehicle industry created a new quality standard IRIS (International Railway Industry Standard). IRIS goes beyond the ISO norms and takes account of the high quality requirements in the rail industry. HANNING & KAHL, as manufacturer of safety products for rail applications, was the first company in the world to be successfully certified for compliance with the new IRIS standard. 

HANNING & KAHL brought the world‘s first electro-mechanical braking system for wind turbines and other industrial applications onto the market. Today, modern and environmentally-friendly wind turbines are equipped with our electro-mechanical braking system which provides greater safety and are much more economically efficient over their life cycle than hydraulic brakes.

We founded our own subsidiary in the USA, the HANNING & KAHL L.P. The step was the logical conclusion of the huge success of our products on the North American market – prompt service and maximum proximity to customers have enabled us to strengthen our position there.

In this year, HANNING & KAHL also took over the majority holding in Verkehrsautomatisierung Berlin GmbH. The company develops typical traffic-software solutions e.g. depot and infrastructure management as well as control and information systems.

The first, in-house developed, railway-suitable, fail-safe microprocessor controller which complied with AK 6/SIL 3 was launched. This vital processor system replaced the relay technology and the industrial PLC controllers common in the railway sector at that time. Today, this microprocessor controller is available in SIL 4, and is used to construct controllers, signalling installations and interlocking controllers. This in-house, rail-specific controller is a vital tool when it comes to mastering the crucial issue of obsolescence management. 

HANNING & KAHL moved to new and modern premises in Oerlinghausen when the buildings in in Bielefeld could no longer accommodate the company's rapid growth despite repeated extensions.  

HANNING & KAHL was the first company in the world to launch a hydraulic braking system for rail vehicles … decades ahead of other suppliers. Today, our hydraulic brake systems are in operation in trams and LRVs and also in metro vehicles and people movers all over the world. 

Saw the market entry of the electro-magnetic point machine, the legendary “HW 200“, and of the first point controller. Both products have been continually advanced over the decades. Today, electric and mechanical point machines and controllers are available for virtually all point types and rail transportations systems up to safety integrity class SIL 4, and are in service worldwide. 

Saw the market launch of the electro-magnetic track brake, the first safety product for rail-based public transport. Today, electro-magnetic track brakes are still a key component of our braking systems. 

The company which constructed motors and generators was founded by the Hanning family and the Kahl family in Bielefeld. Over the decades, HANNING & KAHL developed into the Hanning Group - a global corporate group with several independent companies which today is still 100 % owned by the Hanning family now in the third generation.
