施工升降機是建筑中經常使用的載人載貨施工機械，主要用于高層建筑的內外裝修、橋梁、煙囪等建筑的施工。由于其獨特的箱體結構讓施工人員乘坐起來既舒適又安全，已被公認為高層建筑施工不可缺少的關鍵設備之一。施工升降機主要組成部分如下：導軌架、吊籠、傳動系統、附墻架、底架護欄、電氣系統、安全保護裝置、電纜供電裝置等。

1、施工升降機的安全開關都是根據安全需要設計的，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。為了避免事故隱患的發生，使用單位領導應該加強管理，嚴格要求升降機維護和操作人員定期檢查各種安全開關的安全可靠性，杜絕事故的發生。
Construction elevator safety switches are designed according to the security needs, fenced door stopper, hanging kennel limit, Dingmen limit, limit switches, upper and lower limit switches, heavy anti-broken rope protection switch. In order to avoid the occurrence of accidents, the use of unit leaders should strengthen management and strict requirements lift maintenance and operations personnel regularly check the safety and reliability of various safety switches, to prevent accidents.   

2、施工升降機各?？繉討O置?？堪踩雷o門。如果不按要求設置，在高處等候的施工人員很容易發生意外墜落事故。在設置?？堪踩雷o門時，應保證安全防護門的高度不小于1.8m，且層門應有聯鎖裝置，在吊籠未到停層位置，防護門無法打開，保證作業人員安全。
Each stop layer construction elevator safety door stop should be set. If you do not follow the requirements set in the height of construction workers are prone to accidents waiting to fall accident. When setting docked security doors, security doors should ensure a high degree of not less than 1.8m, and the landing door interlock device should be in the position of the cage yet reached the stop layer, protective door can not be opened, to ensure worker safety.

3、施工升降機采用變頻調速對制動器無磨損，任意低的就位速度，平層精度高；速度的平滑過渡，對機構和結構件無沖擊，提高了升降機的安全性；幾乎任意寬的調速范圍，提高了升降機的工作效率；節能的調速方式，減少了系統運行的能耗等，正是因為這些明顯的特點和優勢，使變升降機的安全運行和減少運行能耗有重要的意義。
Frequency control of construction hoist brake wear, place arbitrarily low speed, high precision leveling; smooth transition speed of institutional and structural parts without impact, improving the safety of lifts; almost any wide speed range improve the efficiency of lift; energy-saving speed, reducing the energy consumption of the system is running, etc., precisely because of these distinctive features and advantages, so that becomes the safe operation of lifts and reducing energy consumption has important significance.
