1、導軌升降機纜盤落到了儲存筒外；電纜絕緣外皮破損；電纜與防護設施干涉，吊籠在升降過程中檢查電纜絕緣外皮有無破損，電纜與腳手架等設施是否有干涉，下降過程中經常檢查電纜有無盤落在電纜儲存筒之外的現象。
The elevator cable plate fell on the storage cylinder outer skin damage; cable insulation; cable interference and protection facilities, cage check in process of lifting cable insulation sheath is damaged, cable and scaffolding and other facilities are there is interference, the process of decline often check the cable without falling outside the disk storage cylinder in the phenomenon of cable.
2、導軌升降機導架變形，移位；導架膠皮缺損；導架安裝位置不規范，吊籠升降過程中檢查電纜導架有無變形移位，導架膠皮有無缺損，在地面檢查電纜導架是否按規定安裝。
The elevator guide frame deformation, displacement; guide rubber defect; guide the installation position is not standard, the frame has no displacement guide check cable cage lifting process, the guide frame rubber has no defect, whether in accordance with the provisions in the ground check cable installation guide.
