The invention discloses an escalator structure. The escalator structure comprises a stair, a traction system, an escalator way guiding rail system, a driving device, a tensioning device, a metal structure and a safe device. The stair comprises a stair body with two sets of wheels, one set of wheels are main wheels connected to the traction system, the other set of wheels are auxiliary wheels directly installed on short shafts of stair supports, and the base distance between the main wheels and the auxiliary wheels ranges from 310 mm to 350 mm. Grooves are formed in the surface of the stair body, and in this way, when passing through an upper exit and a lower entrance of an escalator, the stair can be embedded into comb plate teeth so as to guarantee that passengers can enter the escalator or exit from the escalator safely. The riser surface of the stair body is a circular arc surface, a skeleton of the stair body is composed of supports on the two sides and a transverse connection part composed of sheet material or angle steel, and aluminum alloy branched parts are adopted for forming the stair body in a die-casting and splicing mode. The escalator structure is light in weight, good in technology performance and convenient to assemble, disassemble and maintain.
