成都升降機 http://m.heyuanwai.cn/的安全開關都是根據安全需要設計得，有圍欄門限位、吊籠門限位、頂門限位、極限位開關、上下限位開關、對重防斷繩保護開關等。Chengdu elevator safety switch is designed according to the requirement of safety, there is a fence, cage threshold limit, the limit, the limit switch, limit switch, anti broken rope protection switch.

一些工地上為了省事將一些成都升降平臺限位開關人為取消和短接或損壞后不及時修復，就等于取消了這幾道安全防線，種下了事故隱患。例：吊籠要裝載長東西，吊籠內放不下需伸出吊籠外，而人為取消門限位或頂門限位，在上述安全設施不完善或不完好得情況下，照樣載人載物，這種違章作業是拿人生命開玩笑得。Some sites in order to save some of the lifting platform Chengdu limit switch for cancellation and shorting or damage after not timely repair, is cancelled this line of defense, planted the hidden dangers of accidents. Example: the cage to load long things, the cage is not put out to the cage, and cancel the threshold or the human limit, the safety facilities are not perfect or not good situation, still manned loading, the illegal operations take life joking.

為了避免事故隱患得發生，希望使用單位領導加強管理，嚴格要求成都升降貨梯維護和操作人員定期檢查各種安全開關得安全可靠性，杜絕事故得發生。In order to avoid the hidden dangers of accidents have occurred, want to use the unit leaders to strengthen management, strict Chengdu lifting elevator maintenance and operations personnel to regular inspection of various safety switch safety reliability, prevent accidents have occurred.
