color: rgb(64, 64, 64); font-size: 14px;">（1）通過式拋丸機負荷試驗對于新投入使用的吊鉤及使用一段時間的吊鉤應做負荷試驗，以額定載荷的1.5倍作為試驗載荷，通過式拋丸機載荷懸掛時間不少于10min，卸載后不應有永久變形。吊鉤使用一段時間后，由于鋼絲繩的作用，往往使吊鉤表面硬化。為防止這種表面硬化，可每半年到一年作一次退火處理，但必須根據材質控制溫度，否則反而會使吊鉤金屬晶粒變粗，影響使用壽命。<br /> （2）安全檢驗吊鉤每年至少應進行次全面檢驗，對于頻繁使用的吊鉤每季度至少進行次檢驗。檢驗前應用煤油洗凈鉤體，用20倍放大鏡檢查危險斷面，不得有裂紋、通過式拋丸機塑性變形、鉚釘松動等現象。<br /> （3）安全檢查應根據工作繁重、環境惡劣的程度確定檢查周期。主要檢查吊鉤有無裂紋、變形及吊鉤螺母和防松裝置有無松動，檢查襯套、心軸、小孔、耳孔以及其緊固件的磨損情況。報廢標準不準使用鑄造吊鉤；鉤體表面光潔，無裂紋，剝裂及任何有損傷鋼絲繩的缺陷；鉤體上的缺陷不得焊補；吊鉤上應設置防止意外脫鉤的安全裝置。<img title=" 通過式拋丸機 "
