The trailer ended up in a field with the tractor unit upside down on the road after the collision on the A713 near Parton, in the Stewartry, at about 10.45 pm on Monday.
And heavy lifting gear had to be brought in to remove it on Tuesday.
The Daf lorry which was towing a trailer with the bottom section of a turbine trailer on it left the roadway completely blocking the main road.
The vehicle was part of a convoy being escorted to the Brockloch Windfarm site at Carsphairn.
