[0037] In use, first, the position of the mounting seat 1 provided with the arresting hook 2 is adjusted, so that the included angle of the arresting cable 3 reaches a specified degree, and then the driving device 4 drives the arresting cable 3 to reciprocate to wear the arresting hook 2.

[0038] It can be understood that in other embodiments, the test platform can also be the ground, a mounting rack and the like.

[0039] In some embodiments, the arresting hook wear resistance testing equipment provided by the embodiment of the utility model further comprises a first fixed pulley 6 and a second fixed pulley 7, and the first fixed pulley 6 and the second fixed pulley 7 are rotatably arranged on the test platform 5. Figure 1The mounting seat 1 is arranged between the first fixed pulley 6 and the second fixed pulley 7 along the first direction (e.g. the left-right direction shown in the figure) and is arranged on the side of the first fixed pulley 6 and the second fixed pulley 7 along the second direction (e.g. the front-rear direction shown in the figure), and the second direction is perpendicular to the first direction.
