  • Publication number: 20080271953
    Abstract: An incline lift unit (2) is designed for conveying a load along a guide (3) with a varying angle of inclination. The incline lift unit (2) comprises a conveying unit (5), which is designed to be carried by the guide (3) and to move along the guide (3). The incline lift unit (2) comprises a load carrier (4), which is rotatably connected to the conveying unit (5). The incline lift unit (2) comprises rotation means (31) and a control unit (37) for driving the rotation means (31) in such a manner that the load carrier (4) assumes a desired orientation relative to the vertical. The conveying unit (5) comprises a conveying frame (29) and two-gear mechanisms (41). The gear mechanisms (41) are rotatably connected to the conveying frame (29) and comprise a gearwheel (49). The gearwheel (49) is intended for engagement with a gear rack (22) of the guide. The incline lift unit (2) furthermore comprises detection means (55) for detecting a difference in rotation of the gearwheels (49).
