In the strength test, the test is completed by simply obtaining the force applied by the hydraulic machine 32 to the fork and then observing whether the fork is damaged. Accordingly, the hydraulic machine 32 should be equipped with a force detection module, for example, a pressure sensor or the like may be used to detect the force applied by the hydraulic machine 32. The principle of strength detection by the hydraulic machine 32 is conventional in the art, with specific reference to the prior art.
