Our self-propelled carriages are installed on rails above towing tanks, sea-keeping and manoeuvring basins, ocean basins, flumes or ice tanks. They are used to tow scaled, instrumented models through still water, waves or ice. We supply a wide range of sizes and configurations, from small educational carriages for university laboratories, through to high speed towing carriages for ship design evaluation and research. We also design and supply multi-axis motion carriages for sea-keeping and manoeuvring basins and ocean basins. These have an integrated sub-carriage for forced model manoeuvres using a towing system, as well as the ability to track free-sailing models.
We build carriages for tanks from 1.5 up to 50 metres wide. The carriage speed and rails are tailored to the type of tests, vessels and model scales that the facility is designed for. For example slow, carriages with speed accuracy for ice tests or high speed carriages for naval applications.
