The invention discloses a dragging belt of composite materials. The dragging belt is light in weight and good bending performance. The dragging belt comprises a plurality of inner bearing body layers and abrasion-resisting elastic bodies wrapped outside the inner bearing body layers. The inner bearing bodies are in a sheet shape which is continuous in the single length direction of the dragging belt. Each inner bearing body comprises a base body. A plurality of nonmetal non-twist continuous fiber monofilaments are arranged in the base bodies, the nonmetal non-twist continuous fiber monofilaments are not in contact, the base bodies of inner bearing body layers are made of thermosetting resin materials or thermoplastic resin materials, the abrasion-resisting elastic bodies are thermoplastic polyurethane or rubber elastic bodies. At least two inner bearing body layers are arranged in the thickness direction of the dragging belt. The thickness of the inner bearing body layers of the sheet-shaped structure of the dragging belt is small, under the premise that good bearing is achieved, bending curvature radius is greatly lowered, the obtained dragging belt is light in weight, high in intensity and easy to bend, abrasion resistance and whether resistance are achieved, anti-fatigue performance is achieved, service life is long, maintaining cost is low, and the dragging belt can be used for lifting of long-distance heavy objects.
