Embodiment Construction
[0013] Examples see figure 1 As shown, the sliding device of this double tower mast giant self-elevating lifting equipment is composed of a PTFE plate 1, an elastic backing plate 2 and a steel bottom plate 3 bonded from top to bottom. The PTFE plate The upper surface is uniformly covered with granular micro-protrusions 5, the gaps between the micro-protrusions are oil injection holes 4, and a circle of guards 6 is formed around the tetrafluoro plate, and the height of the guards is the same as that of the micro-protrusions 5 . The above-mentioned elastic backing plate 2 can be rubber or plastic.
[0014] The invention can be processed into a square shape, and the use is not limited by the direction, as long as the direction of the force is changed, it will walk in the opposite direction of the force, which is very convenient to use.
