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