貨梯一般都是高空作業，危險性極高，每臺浙江貨梯都設置手動泄壓閥，原因其實是為了預防貨梯如果在升起的狀態出現意外情況，比如意外的停電了，或者升降按鈕失靈了，導致貨梯不能下降。
Zhejiang freight elevators are generally high-altitude operations, the risk is very high, each Zhejiang freight elevators are set manual pressure relief valve, the fact that, in order to prevent Zhejiang freight elevators in the event of unforeseen circumstances raised state, such as an unexpected power outage, or lift button failure, resulting in Zhejiang freight elevators can not fall.

我們在貨梯的控制系統上設計了手動泄壓閥，一旦出現意外情況，可以擰一下這個泄壓閥，貨梯就會下降，然后把泄壓閥再擰緊，或者會導致貨梯不能升起。為了保證升降平臺不發生意外，在使用貨梯進行加工的時候，確保設置手動泄壓閥，且無任何故障。
We designed the Zhejiang freight elevator control system manual pressure relief valve, in the event of unforeseen circumstances, you can squeeze about this pressure relief valve, Zhejiang freight elevator will drop, and then re-tighten the pressure relief valve, or may not lead to rising freight elevators Zhejiang . In order to ensure the lifting platform is not an accident, in the use of the freight elevator Zhejiang processing time, be sure to set a manual pressure relief valve, and without any fault.
