CALAF TRENCHING continues to invest in R&D and has received funding from the CDTI. This funding is co-financed by the European Regional Development Fund (ERDF) through the Pluri-regional Intelligent Growth Operational Program for the realization of the " TDC TRENCHER R&D PROJECT ", a very versatile urban trencher model for trench widths to be excavated from 3 cm (fiber optic installations) to 45 cm (gas, water, urban collectors, etc.), which incorporates in a single equipment a higher functionality and versatility with respect to the equipment that exists in the market.
