A door maneuvering arrangement for opening and closing a door. The arrangement includes a line loop connected to a part of the door, a drive wheel, a motor for reversibly rotating the drive wheel and a plurality of guide pulleys for guiding the line loop. First guide pulleys are mounted in the vicinity of the drive wheel and cause a first line section of the line loop to bear on and extend in an omega-shape path around a first portion of the circumference of the drive wheel. Second guide pulleys are mounted in the vicinity of the drive wheel and caused a second line section of the line loop to bear on and extend in an omega-shape path around a second portion of the circumference of the drive wheel. |
