The invention concerns a cassette lift (40) for a vehicle (31), that has a doorway (33) and a stair (34) inside thereof, said stair in several steps (36) leading up from an entrance landing (35) to a vehicle floor (37). The cassette lift (40) comprises a horizontal platform (41), which in a resting position is inserted in one of the lower steps (36) of the stair (34) in order to be advanced from there for use with the aid of a slide (42) and thereafter with the aid of a linkage system, which is flexibly connected with both the slide (42) and the platform (41), to be moved vertically between a ground level (N) on the outside of the vehicle (31) and a level in level with the vehicle floor (37). The link system is divided into a first (43) and a second (44) parallel linkage system, which systems are flexibly connected to each other. The first parallel linkage system (43) has arms (45, 46) which in order to enable substantially vertical movement of the platform (41) are arranged to pivot within a first angular area including horizontal level. The second parallel linkage system (44) has arms (49, 50) which for a mixed vertical and horizontal movement of the platform (41) are arranged to pivot within a second angular area substantially from horizontal level and upwards. |
