Llauts, traditional wooden boats about 20 or 25 meters long, were essential to transport up to 30 tons of [[lignite]] on each trip. Constructed of local hardwood, the Llauts used the current of the river to make the journey south, and when they had to return to Mequinenza they could use wind extending the square sails that the skipper maneuvered. When the wind was not blowing enough or it was contrary, the Llauts had to climb the [[towpath]], that is, pulling them from the shore upstream This was known as "Camí de Sirga" (or [[towpath]] in English). Until 1914 the towpath was made by three men for each Llaut that were relieved every hour and a half or two hours. Carbonífera del Ebro made an attempt to incorporate steamships to transport lignite, but the Ebro's drainage and its complicated orography made its use too difficult. Flix Electrochemical Society (SEQF), which had mining concessions in Mequinenza, decided in 1920 to suppress the human force and change it for [[Working animal|animal traction]]. This was a unique transport system in the world, in which the coal that was extracted from the mines, led to different landings at the foot of the river and transported by river route to [[Tortosa]] or [[Fayón]].
