The conveyor in Asa (Kjerraten i Åsa), dating from the period 1807-1850, was a system to transport timber up a hillside. The conveyor consisted of 12 water wheel with a chain between. It had a vertical drop of 389 meters over a total length of 3900 meters. It took 3 hours to carry a timber through the conveyor, which had a capacity of approximately a log every sixth minute. The conveyor was originally filed by Norwegian businessman and politician.Peder Anker from Bogstad, who owned large areas of forest in the area. He needed a solution to transport timber from Steinsfjorden in Åsa up to lake Damtjern and Storflåtan before floating it down to Sørkedalsvassdraget.
