Our customer
Transdev Deutschland is part of the international Transdev Group. The mobility provider, headquartered in Paris, is active in many countries and has many years of experience in public transportation. Blaschke Umwelttechnik has been a partner of Transdev Deutschland for many years and has equipped numerous of the company's own workshops with individual extraction solutions. Since 2006, this has also included the Husum-based Transdev Instandhaltung GmbH (TDI), which provides a high-quality and individual maintenance and repair service for locomotives, passenger coaches and freight wagons in accordance with EBO, DIN 27200, VPI and the specifications of the vehicle owners.
Our task
From the construction of the new TDI workshop in 2006 until the changeover of railcar types in 2020, our tried-and-tested swivel arm systems at fixed workstations ensured clean air in the workshop. With the introduction of the new railcar types and various new vehicle generations, a more flexible yet easy-to-use exhaust extraction system was required. As many of the existing and, after more than 15 years, still functional parts as possible were to be used.
Blaschke Umwelttechnik was awarded the contract to manufacture and install an effective system for extracting harmful DME pollutants for the combined maintenance hall. The system had to meet the following requirements Extraction of different vehicle types - Ease of operation - Integration into the structural conditions without major architectural changes - Use of the built-in overhead cranes in alternating operation - Guarantee of a high safety standard in the combined operation of crane and extraction system. Together with the workshop management of Transdev, Blaschke Umwelttechnik designed an optimally adapted system variant taking these requirements into account.
Our solution
As the legal requirements for precise, effective extraction had to be met in addition to the customer-specific requirements, the so-called BRB system was the ideal starting model. This particularly flexible and space-saving system is characterized by two slotted ducts that are attached to the concrete or steel supports of the building parallel to the track, one above the other. They serve as suction and at the same time as guide rails for one or more collection units.
At the TDI workshop in Husum, 5 swivel arms with height-adjustable extraction hoods and 4 electric hose reels were used for the additional extraction of the underfloor heating systems. The system was equipped with a modern PLC control system and various sensors for height and distance control. This means that the various collection units, individually or together, can be conveniently moved to the desired extraction points using a remote control.
Incidentally, precise extraction is not only effective, it also ensures that pollutant deposits in the hall and false fire alarms from smoke detectors are avoided.
"As a modern maintenance workshop in the rail industry, we are constantly working on improving our services and the associated development of our workshop infrastructure. In order to meet the requirements of our customers and the market even better, it became necessary to improve the flexibility of our exhaust extraction system. In Blaschke, we were able to find a reliable partner who supported us with this challenge in a targeted and proven manner. The solution created and installation implemented by Blaschke has filled us with enthusiasm and far exceeded our expectations."
