Three time self-locking detection of differential gearbox with small details

The self-locking ability of the differential directly determines the safety of high-altitude workers, so the differential will undergo at least three self-locking tests before use to ensure that there are no problems before use. There is a small detail to note about the three self-locking tests of the differential, which will be briefly explained by Crown Airlines.

As we all know, the self-locking detection method of the differential is carried out by quickly pulling the steel wire rope. When the steel wire rope completes the braking within a very short stretching range, it means that the self inspection is passed. Then, it is repeated more than twice. If all tests pass, it is qualified and can be used with confidence. But strictly speaking, there is a standard operating method for the three time self-locking detection.

After the first self-locking of the wire rope, we should try not to return the wire rope to its initial position again during the second inspection. Instead, we should perform the second self-locking inspection after retracting a small section, and then perform the third and fourth inspections in the same way. The purpose is to prevent the differential from forming self-locking at the same point, thereby ignoring more ratchet and pawl self-locking points.

Guanhang hopes that everyone can pay attention to this small detail when testing the self-locking of the differential, and learn to perform this testing method with inertia, so as to better ensure the safety of the differential's use.
