重慶升降平臺是一種用來(lái)運送貨物和器材到指定高度進(jìn)行作業(yè)的特種設備，升降平臺的安全開(kāi)關(guān)都是根據安全需要設計的，有圍欄門(mén)限位、吊籠門(mén)限位、頂門(mén)限位、極限位開(kāi)關(guān)、上下限位開(kāi)關(guān)、對重防斷繩保護開(kāi)關(guān)等，避免了用腳手架和梯子的不方便及危險因素。

1、防墜安全器是施工升降平臺上重要的一個(gè)部件，要依靠它來(lái)消除吊籠墜落事故的發(fā)生，保證乘員的生命安全。因此防墜安全器出廠(chǎng)試驗非常嚴格的，出廠(chǎng)前由法定的檢驗單位對它進(jìn)行轉矩的測量，臨界轉速時(shí)測量，彈簧壓縮量的測量，每臺都附有測試報告，組裝到施工升降機上后進(jìn)行額定載荷下的墜落試驗。
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、施工升降平臺上的緩沖器是施工升降平臺安全的最后一道防線(xiàn)，它必須有一定的強度，能承受升降機額定載荷的沖擊，且起到緩沖的作用。
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、設有防止液壓管路破裂的安全保護閥，液壓管路破裂容易發(fā)生，一旦發(fā)生危險性大，防止液壓管路破裂的安全保護閥可以避免這種危險的發(fā)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、設有停電情況下的應急下降裝置。升降機突然停電，可致正在作業(yè)的升降機直速下降，危險性很大，設有停電情況下的應急下降裝置，就方便可靠了許多。
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，作業(yè)環(huán)境條件惡劣，水泥、砂漿、塵土不可能消除干凈，齒輪與齒條的相互研磨，齒都磨尖了仍然還在使用，應當引起重視。
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.
