升降貨梯http://www.it616.com.cn/常見的故障有制動系統液壓站電動機故障、錯向運行、兩終端過卷揚或超速、主電動機失勵磁、直流主回路過電流或過電壓，以及保護回路失電等問題，一旦發生該類事故，則必須馬上斷開交、直流回路并進行制動停車。事故停車故障包括制動輪變形、兩終端之間超速、安全門打開、緊急停車后未調零或調零電機故障、操作限位開關失靈以及尾繩故障等，而信號預警類的故障不需停車，而應以光、聲等預警信號提示作業人員，該類故障主要包括直流操作電流接地、直流主回路接地、直流主電機軸承過熱、制動閘瓦磨損以及通風故障等。引發升降貨梯出現故障的因素主要包括操作人員誤操作或違反工藝規程，現有裝置的保護功能不夠完善，設備結構復雜對維修人員的技術經驗要求過高，成都升降機長時間、高強度工作而設備故障的早期預兆未被注意等。
Common faults cargo lifter hydraulic brake system of the motor failure, wrong to run over two terminal winch or speeding, lost the main motor excitation, DC main circuit overcurrent or overvoltage protection circuit as well as issues such as loss of power, in the event kind of accident, you must immediately disconnect the AC and DC circuits and parking brake. Parking fault accident, including brake wheel deformation between the two terminal speed, security door open, not adjusted after an emergency stop zero or zero motor failure, operation of the limit switch failure and tail rope failure, and the signal failure without warning like parking , but should be light, sound and other warning signals prompted workers, such failure include DC operating current grounding, DC main circuit grounding, DC main motor bearings overheating, brake pad wear and ventilation failure. Factors that lead to failure of the main cargo lifter include operator misuse or breach of technical rules, protection of existing installations is not perfect, the device structure of complex technical experience requirements for maintenance staff too, Chengdu lift a long, high-intensity work and equipment early harbinger of failure and so unnoticed.
升降貨梯出現故障時，應該及時對出現故障的原因進行分析，以便及時為檢修人員排除故障提供科學的依據。因此大家應該做好升降貨梯事故狀態的初期預測及應對措施，也是決定故障是否能夠有效排除的關鍵，必須對升降貨梯http://www.it616.com.cn/進行全方位的監測，對各類故障的位置和成因進行判別，并采取有針對性的措施進行處理。
When cargo lifter fails, should be timely to analyze the reasons for failure to timely maintenance personnel to troubleshoot and provide scientific basis. Therefore, we should do the initial state Huoti accident prediction and response measures, but also the key to whether the failure to effectively decide to exclude, you must carry out a full range of cargo lifter monitoring, fault location and causes all kinds of discriminate and adopt targeted measures to deal with.
