Abstract
En lyftdörrs lyftmekanism omfattar en första axel (20a), som har första spolar (22a) för upphängningsorgan som rullas upp på de första spolarna, och åtminstone en första motor (28a) för roterande av den första axeln. Lyftmekanismen omfattar därtill åtminstone en andra axel (20b), som ligger bredvid den första axeln, på ett avstånd från den första axeln. Den andra axeln har andra spolar (22b) för upphängningsorgan som rullas upp på de andra spolarna. Upphängningsorganen är fördelaktigt lyftkablar (24). Fördelaktigt är den första axeln och den andra axeln kopplade till varandra med åtminstone en taktgivare (30) som synkroniserar axlarnas rotationshastighet.
