卸扣 一般都是两倍安全拉力系数作为负载实验的。 The wire rope shackle is generally used as a load test for twice the safety pull factor. During the test, it should be ensured that the shackle product is under normal operating conditions, and avoids stress on the side or other parts. 卸扣 的轴销不能发生变形,更不允许永久性的形变,并且可以轻松地拆卸下来。 After the test, it is required that the shackle pin cannot be deformed, and permanent deformation is not allowed, and it can be easily removed.


Shackle size and pin should not be too long and should not exceed the standard 0.25%. Shackle products with a load of more than 300 tons should be tested with a working safety load of about 1.4 to 1.5 times, and other special-shaped products should be subjected to load tests according to the use conditions.


In addition, the wire rope shackle should also be checked for appearance and surface treatment. The first is that the surface should be flat and smooth, and neither light nor dark lines should be present. The obvious body cracks in the body can be directly seen. The internal dark lines or small dark lines can be detected with a magnifying glass or a professional infrared detector. The safety load of the factory wire rope shackle is generally approved according to the M4 standard.


In addition, related products must be typed in the body. The typed content generally includes the product's strength level, safety load, breaking factor, and factory standard or product Peugeot. In the use of wire rope shackles and other hardware products, often involved in valuables and construction life and property safety, so only qualified and safe products can be distributed to the market. Therefore, higher and stricter requirements are imposed on the inspection of products.
