起重机械钢结构是起重机重要组成部分,一旦损坏极易发生重特大人员伤亡和财产损失事故。钢结构损坏原因很多,只有掌握了钢结构的损坏原因,才能做好钢结构的预防措施.钢结构损坏的原因主要是以下原因:1.由于在腐蚀环境中作业造成的表面锈蚀;2.由于焊接工艺和使用条件造成的裂纹3.由于碰撞等原因造成的弯曲变形和长期超载或满载造成的永久变形;4.由于超载设计不合理和疲劳等造成的断裂.根据钢结构损坏的不同原因进行预防,保证钢结构使用的安全,严格执行检验制度和操作规程制度,确保起重机械安全运行.
Crane steel structure is an important part of the crane, once the damage is extremely vulnerable to serious personal injury and property damage accidents. Steel structure damage for many reasons, only to grasp the causes of damage to the steel structure, can do a good job in the prevention of steel structure.The main reasons for the steel structure damage are as follows: 1 due to corrosion in the environment caused by surface corrosion; 2 due to Welding process and conditions of use caused by the crack 3 due to collision and other causes of bending deformation and long-term overload or full load caused by permanent deformation; 4 due to overload design unreasonable and fatigue rupture, etc. According to the steel structure damage for different reasons Prevent and ensure the safety of the use of steel structure, strictly implement the inspection system and operating rules and systems, and ensure the safe operation of lifting appliances.
