[0044] In this embodiment, two second support assemblies 7 are provided to further provide more stable support, ensuring that the track elements 2 at both ends are supported by components when they are lowered. More specifically, the second support assembly 7 is a heavy-duty hydraulic cylinder that can carry track elements 2 with a larger mass.

[0045] In an embodiment of the lifting track, there are two guide groups, which are respectively arranged on both sides of the transmission member 41 , and the two guide rails 52 guide and limit the rotation of one transmission member 41 .

[0057] In combination with the previous embodiment, the extending direction of the transmission member 41 is perpendicular to the first cover plate 42 connected thereto, and / or the guide rail 52 is guided parallel to the vertical direction.
