High-quality steel rectangular pipe is adopted to manufacture the truss of escalator with higher rigidity than conventional steel angle truss and better loading capacity, making the running of escalator more stable and better adapting the actual conditions of China that the passenger flow volume is large; the running track system adopts high-intensity cold-drawn flat steel and high rigidity section steel with high dimensional precision and good wear-resisting property; automatic lubricating device largely reduces the maintenance work; the equipment is real-time monitored through multiple safety protection devices, which guarantees the safety of equipment and personnel to the maximum.
