The invention discloses a traction elevator structure. The traction elevator structure comprises a traction machine arranged in an elevator shaft, a lift car system, a counterweight system and a transmission rope, wherein the traction machine comprises a traction wheel, the lift car system involves a car framework, two lift car running guide rails and a lift car pulley block, the counterweight system involves a counterweight frame body, two counterweight running guide rails and a counterweight pulley block, the traction machine and the counterweight system are both arranged on the rear side ofthe lift car system, and the traction machine and the counterweight system are arranged on the inner side of the width direction of the lift shaft; the acute angle range of an included angle betweentwo lines formed by projections of an axial center extension line of the traction wheel and a center connecting line of the two lift car running guide rails on the same horizontal plane is 45 degrees- 90 degrees; and the traction elevator structure further comprises a first guide row wheel assembly and a second guide row wheel assembly. According to the traction elevator structure, the shaft utilization rate is high, the size required for a top layer is small, the positions of the lift car pulley block and the lift car framework can be flexibly designed according to needs, and the adaptability is high.
