A motor-driven open-ended spanner 1 has an open spanner wheel 5 which has a friction surface or toothing receiving rotational drive, characterised in that the spanner wheel is driven from at least two points 9, 10, in particular via two friction or gear wheels 11, 12, the distance A between which is greater than the width W of the jaw opening 7. The width W of the jaw opening 7 corresponds approximately to the width across the flats of the spanner wheel 5. <IMAGE> |
