Since it was set up in 2011, the Takuvik mixed international unit has been trying to gain a better understanding of the impact of current environmental disruption (climate, human, etc.) on Arctic marine ecosystems and terrestrial geosystems. The unit is carrying out a research programme called Green Edge, led jointly by French and Canadian scientists, in Nunavut, a territory in northern Canada.
To help them to carry out this study successfully, sampling is regularly carried out from a base camp on the sea ice. A winch with a tripod as an anchorage point overhanging a hole made in the ice is used by the scientists to lower and lift various oceanographic instruments (sampling probes, etc.) as part of their research.
It is a tailor-made solution that has been designed and produced in France by the HUCHEZ Engineering Department: a winch both achieving the desired improvements (speed, precise winding/unwinding of the rope) and meeting the specific constraints of this kind of project (considerable rope capacity and use in extreme conditions on a site that is difficult to access).
The specific lifting winch of a capacity of 150 kg on the last layer includes protection to ensure a long life (marine paint, stainless steel rope and hook). It is also equipped with a cross-threaded screw. This device makes it possible to guide and wind the rope quickly and effectively on to the drum.
Installed on site several weeks ago, the winch is now operating in research missions every day.
