1, good stability. Adopt rectangular square tube rafter structure with strong rigidity, so the natural escalator has high strength and stability.
2, high security. In order to ensure the running safety of the escalator to the greatest extent, when installing the elevator, the bolt jacking method is adopted to avoid the displacement of the main engine caused by the fracture of the bolts and other fixing devices due to excessive stress, thus avoiding the occurrence of potential safety hazards.
