  五一牌手拉葫芦的某些错误操作早已是屡见不鲜，但是总还有一些用户为了所谓的省时，而不惜违规操作，直到危险发生时，才追悔莫及，小编在此再次为大家总结这些错误操作及后果，为保安全，希望大家能加以注意。
May the player hoist some of the wrong operation is already but there are some users It is often seen., for a time, at the expense of illegal operations, just too late to regret until the danger occurs, in this small series, again we summarize these errors and consequences for the security of all, hope everybody can pay attention to.
 曾经我们也有过如海子一般“面朝大海，春暖花开”的美好愿景，曾经我们也为“那一年”的往事刻骨铭心，曾经我们也不知道忙碌夜夜狂欢，曾经我们也有过假装欺骗自己……在我们过去的时光里，一件件悲伤的、快乐的往事像一粒粒珍珠般串联在一起，构成了我们如花似玉的年华。


       第一点、超载：超载是最长出现也是最为严重的错误操作之一，某些用户可能会说手拉葫芦链条断裂所需负重要远大于其额定载荷，因此只要超载不达到这个限度不就不发生危险了吗？其实不然，只要超过其额定载荷，其组件变形系数就会发生轻微的改变，长此以往，组件就会出现不可逆转的变形，最终达到报废程度。
The first point: overload overload is the most long is one of the most serious errors, some users may say manual hoist required to fracture the negative important is far greater than the rated load, overload does not reach this limit so long as not dangerous? In fact, as long as more than its rated load, its component deformation coefficient will change slightly, and over time, the component will appear irreversible deformation, and eventually reached the level of scrap.
