A compact servo drive for doors has two drive wheels (2, 3), at least one of which is powered, linked by an endless track, or chain, (4) with an outer profile. The drive is positioned between two tracks (8, 9) fitted to the doors, with inward facing profiles which mesh with the endless belt. A simple design of endless belt has a doubled sided track profile. The drive can be applied equally to straight drives as well as curved drives. |
