重庆升降平台是一种用来运送货物和器材到指定高度进行作业的特种设备，升降平台的安全开关都是根据安全需要设计的，有围栏门限位、吊笼门限位、顶门限位、极限位开关、上下限位开关、对重防断绳保护开关等，避免了用脚手架和梯子的不方便及危险因素。

1、防坠安全器是施工升降平台上重要的一个部件，要依靠它来消除吊笼坠落事故的发生，保证乘员的生命安全。因此防坠安全器出厂试验非常严格的，出厂前由法定的检验单位对它进行转矩的测量，临界转速时测量，弹簧压缩量的测量，每台都附有测试报告，组装到施工升降机上后进行额定载荷下的坠落试验。
Safety device is a component of the construction lifting platform is important to rely on it to eliminate the cage fall accident occurred, to ensure the safety of the occupants. So safety device factory test very strict inspection before delivery by the legal unit of measurement of its torque, the critical speed measurement, measurement of the amount of compression springs, each is accompanied by a test report, assembled to the construction elevator after falling under the rated load test.
2、施工升降平台上的缓冲器是施工升降平台安全的最后一道防线，它必须有一定的强度，能承受升降机额定载荷的冲击，且起到缓冲的作用。
Buffer construction is construction on the lifting platform lifting platform security last line of defense, it must have a certain strength, can withstand the impact of a lift rated load, and play a buffer role.
3、设有防止液压管路破裂的安全保护阀，液压管路破裂容易发生，一旦发生危险性大，防止液压管路破裂的安全保护阀可以避免这种危险的发生。
Security features to prevent hydraulic line rupture valve, hydraulic line rupture prone, in the event of dangerous, safety protection valve to prevent hydraulic line rupture occurred avoid this danger.
4、设有停电情况下的应急下降装置。升降机突然停电，可致正在作业的升降机直速下降，危险性很大，设有停电情况下的应急下降装置，就方便可靠了许多。
Provided emergency lowering device in case of power failure. Lifts sudden power outage, can cause are jobs lifts straight steepest descent, a great danger with an emergency lowering device in case of a power outage, it is convenient and reliable a lot.
5、工地上的施工，作业环境条件恶劣，水泥、砂浆、尘土不可能消除干净，齿轮与齿条的相互研磨，齿都磨尖了仍然还在使用，应当引起重视。
Construction, operation harsh environmental conditions on the site, cement, mortar, impossible to eliminate dust and clean, each grinding gear and rack teeth are sharpened still in use, should pay attention to.
