Abstract: A stairlift for moving along a staircase having: a curved rail having a centre line, a load bearing surface, and a carriage including a first and a second guiding unit connected to each other by a connecting unit. The second guiding unit is connected to the connecting unit via a third rotation joint about a third axis and a fourth joint about a fourth axis, the connection unit includes a fifth rotation joint about a fifth axis. The fifth axis extending from outside the rail to an area close to or on the centre line of the rail in a first plane close to or on the third and the fourth axis.

Abstract: Transport unit 1 for climbing or descending a slope or stairs along a rail provided with a strip, the transport unit comprises a main frame 3 and a guide mechanism 5. The guide mechanism 5 may have at least two guides 13 which guide the transport unit along the rail and a drive mechanism with a drive wheel for driving the transport unit along the rail by engaging the strip at an engagement point. The main frame 3 may be suspended from the guide mechanism 5 in a position around, substantially equal and/or lower than the engagement point.
