Design and construction of special-purpose machinery
Custom machinery.
Perfectly tailored.
Where standard solutions reach their limits, tailor-made machines are required. As a specialist in rail-bound transport routes, we develop and build special-purpose machinery that is precisely tailored to the requirements of modern track systems and construction processes.
Our approach combines technical expertise, years of experience, and a well-thought-out project process: from the initial analysis through design and manufacturing to on-site commissioning. This results in robust, high-performance machine solutions that ensure efficiency, process reliability, and consistently high quality on the construction site.
Flexible machines, precise mixing and pouring
Special-purpose machinery for automated rail casting
In rail casting, uniform material distribution, exact dosing, and controlled installation determine the quality of the entire system. Our specially designed mixing and pouring machines enable continuous and reproducible rail casting – regardless of track length or installation situation.
Through the precise coordination of conveyor technology, mixing systems, and application, various mixing and pouring materials can be processed efficiently. The result is a homogeneous rail support with high durability, reduced installation times, and minimized personnel requirements – a clear advantage, especially during tight track closures and on high-load routes.
VDP mixing and pouring machines are true all-rounders for processing epoxy, polyurethane, polysulfide, and hybrid materials – such as Corkelast ERS. Before a machine is built, we conduct extensive material tests and experimental setups to ensure optimal results for later use.
Material is supplied via 200-liter steel drums, while a dynamic mixing head pours the material precisely. The material mixture is produced under airtight conditions via a flexible hose package connected to the machine – for consistently high quality.
VDP mixing and pouring machines are built modularly and can be transported on various carrier systems – whether by truck, van, or rail chassis. Steel construction, control cabinet construction, electrical control, and programming are carried out entirely in-house in Hagen im Bremischen, so that every machine is perfectly tailored to customer requirements.
Thus, VDP mixing and pouring machines combine flexibility, precision, and performance in a compact, portable system.
Best practices from development
Precise joint processing with specialized technology
Rail joints place special demands on material processing and installation accuracy. Our special-purpose machines for automated rail joint pouring are designed specifically for these sensitive areas and enable defined material quality across the entire joint area.
Automated processes and precisely controlled parameters create permanently resilient connections that reliably absorb movements and extend the service life of the track system. The machines can be flexibly integrated into a wide variety of construction sequences – and ensure consistent results, regardless of external influences.
Flexible, compact, powerful
Crawler undercarriages for mixing and pouring machines
We also offer the matching crawler undercarriages for our VDP mixing and pouring machines.
The system is based on a robust crawler track and is designed for our machines with a total weight of up to 8.0 tons. It ensures reliable traction and high stability even under demanding operating conditions. Depending on the area of application, the undercarriage can be equipped with either white or black rubber tracks, allowing the machine to be optimally adapted to different surfaces and requirements.
A special feature of the system is its extremely compact design: the diesel engine, generator, and hydraulic unit are combined in a very small space and are optimally coordinated. This results in a powerful, space-saving unit that is particularly suitable for applications where efficiency and compact dimensions are required.
Technology from in-house development
Flexible rail blasting machines
We build rail blasting machines that were originally developed for our own use – and are now also available to our customers. Whether stationary container blasting systems, mobile diesel or electric models, or compact small systems – we have the right machine for every task. With our blasting technology, rails, turnouts, or rail joints can be cleaned quickly, thoroughly, and reliably. Efficient, flexible, and ready for any challenge – making blasting a pleasure!
