The invention discloses a truss structure of a large-hoisting-height intermediate-support-free escalator. The truss structure comprises a left single piece and a right single piece. An upper left chord member and a lower left chord member are arranged at the upper end and the lower end of the left single piece respectively. An upper right chord member and a lower right chord member are arranged at the upper end and the lower end of the right single piece respectively. The left single piece and the right single piece are fixedly connected through an upper connecting beam and a lower connecting beam. An intermediate connecting plate is further arranged between the left single piece and the right single piece. According to an escalator truss adopting the structure, the truss can also meet the requirement for the mechanical property stipulated by the national standard under the conditions that the span is large and the truss is free of intermediate support by reasonably selecting the installation structure of the truss and the shapes of the cross sections of the lower chord members.
