Abstract：In order find out the causes of fracture in the service process of wire rope for aerial work, the fracture surface and microstructure of the defective part were analyzed by means of stereo microscope, optical microscope and scanning electron microscope. Meanwhile, the mechanical properties of the normal samples were analyzed using tensile testing machine. The results showed that the white layer microstructure and friction extrusion trace were formed due to the repetitive extrusion and friction between steel wire rope and reserved hole of fixed pully during use. The shear fracture of steel wire rope with damaged surface occurred in repetitive lifting of diagonal tension. The integrity of remaining steel wire rope was destroyed. The fracture of whole steel wire rope was caused when the load-bearing capacity was greater than the ultimate load.
