This invention relates to traction and drive rolling-sliding contact fatigue wear-test machine of elevators, in which, the steel wire rope in the structure of double-groove double-rope semi-circle complement is fixed on a rope groove of a down turnplate, namely, two grooves are opened on the turnplate, a steel wire rope, a bit longer than semi-circle, is winded in each groove, the upper and lower semi-circle ropes are complemented, after that, the rope is fixed in the down turnplate with a clamp, this structure can reduce and avoid the contact vibration between the traction wheel and the rope, the weight amplifies the force by a loaded lever to press the traction wheel to contact with the rope on the down turnplate, the action line of the pressure passes through the center of the two wheels.
