弓形卸扣通過極限拉力試驗，安全性能獲認(rèn)證 Bow shackle passed the ultimate tensile test and its safety

本次試驗嚴(yán)格遵循ISO2415標(biāo)準(zhǔn)及國內(nèi)特種設(shè)備安全技術(shù)規(guī)范，模擬了極端工況下的受力場景。試驗中，弓形卸扣被固定在液壓拉力試驗機上，通過逐步增加載荷至額定工作負(fù)荷的4倍以上，檢測其變形、斷裂臨界點及材料穩(wěn)定性。  

This test strictly follows the ISO2415 international standard and the national special equipment safety technical specifications, simulating the stress scenarios under extreme working conditions. During the test, the bow shackle was fixed on a hydraulic tensile testing machine, and its deformation, critical breaking point and material stability were tested by gradually increasing the load to more than 4 times the rated working load.

 測試數(shù)據(jù)顯示，該卸扣在達(dá)到25噸極限拉力時仍保持結(jié)構(gòu)完整，卸扣本體無裂紋、螺紋無滑絲，卸扣銷軸未發(fā)生塑性變形，完全符合“破斷負(fù)荷不低于額定負(fù)荷4倍”的行業(yè)安全要求

Test data shows that the shackle remains structurally intact when reaching the ultimate tensile force of 25 tons, the shackle body has no cracks, the thread has no slipping, and the shackle pin has no plastic deformation, which fully meets the industry safety requirements of "breaking load is not less than 4 times the rated load".

作為起重吊裝、船舶錨固等領(lǐng)域的關(guān)鍵連接件，弓形卸扣的安全性能直接關(guān)系作業(yè)人員生命及設(shè)備安全。此次試驗通過后，該產(chǎn)品已獲得國內(nèi)船級社（CCS）、歐盟CE等多國認(rèn)證，預(yù)計將廣泛應(yīng)用于海上風(fēng)電安裝、橋梁建設(shè)等重大項目。  

As a key connector in the fields of lifting, hoisting, ship anchoring, etc., the safety performance of the bow shackle is directly related to the life of operators and the safety of equipment. After passing this test, the product has obtained certifications from China Classification Society (CCS), EU CE and other countries, and is expected to be widely used in major projects such as offshore wind power installation and bridge construction.
