Embodiments of a scissor lifting platform comprising at least two crossing lower scissor bars, at least two crossing upper scissor bars articulatedly connected to the lower scissor bars, and a lower joint connecting the two lower scissor bars with each other and an upper joint connecting the two upper scissor bars with each other. Furthermore, the scissor lifting platform comprises at least one lifting aggregate connected to the lower scissor bar or the upper scissor bar and at least one rail having at least one contact area and being supported on the upper scissor bars. The upper scissor bar is articulatedly connected to the at least one rail and the other one of the upper scissor bars is guided by the at least one rail so as to be movable in a longitudinal direction when the scissor lifting platform moves. The lifting aggregate has at least one operating rod which works together with an elevating mechanism for lifting and reinforcing the vertical force up to a predetermined lifting height of the scissor lifting platform. |
