A wheelchair lift (1) comprises a platform assembly (10) to receive a wheelchair and a power control assembly (20) to control a movement of the platform assembly (10) between an unfolded configuration and a folded configuration. The platform assembly (10) comprises an inner plate (11) and an outer plate (12), wherein the inner plate (11) is pivotably coupled to a holding arm (30) by a hinge element (110) and the outer plate (12) is pivotably coupled to the inner plate (11). The wheelchair lift (1) further comprises a linkage assembly (50) having a first end (51) coupled to the outer plate (12) and a second end (52), and a fixing element (60) being coupled to the inner plate (11) such that the fixing element (60) is moved with a rotational movement of the inner plate (11) around the hinge element (110), when the inner plate (11) is moved between the folded and the unfolded configuration, wherein the second end (52) of the linkage assembly (50) is coupled to the fixing element (60).
