An incline lift unit (2) comprises a conveying unit (5), a load unit (4) which is rotatably connected to the latter, a positioning device (20), and a locking device (100). The positioning device is designed to turn the load unit with respect to the conveying unit in such a manner that, in use, the load unit assumes a desired load orientation relative to the force of gravity. The locking device comprises a locking means (133). The locking means locks the rotatable connection between the load unit and the positioning device if the load unit has assumed an undesirable load orientation. The locking device comprises a reference element (131) which is movable with respect to the load unit and the conveying unit, its position with respect to the load unit being determined by the direction of the force of gravity. The load unit is able to assume at least a neutral position and a locking position at the desired and undesired load orientation, respectively, with respect to the reference element. The reference element is mechanically connected to the locking means. The reference element activates the locking means in the locking position. |
