SETTING EVERYTHING IN MOTION.
JUST IN SEQUENCE. The supply and disposal of equipment, products and personnel for tunnel jobsites is decisive for smooth operations. With innovative rolling stock transport systems, we provide support for efficient jobsite logistics. MSD adapts rail-bound transport systems exactly to the specific requirements of your tunnel project.
We develop tailor-made solutions wherever huge forces are at play. For example: hydraulic shield cradles for sloping shaft launches, sliding platforms for heavy railway technology, mechanized back-up systems for posterior profiling and the final completion of tunnels.
