1、 電刷： 應根據移動用電設備使用情況每1—3個月檢查一次。重點檢查集電器電刷的磨損情況，若磨損量≥5mm時，必須更換。檢查時若發現電刷松動或發生磨損偏斜時，應查明原因，及時處理。
1, brush: electric equipment should be based on the use of every 1 - 3 months check once a. Focus on examination of the collector brush wear, if wear is greater than or equal to 5mm, must be replaced. If found loose or worn oblique brush examination, should identify the reasons, timely treatment.
2、 集電器：至少每季度檢查一次。重點檢查緊固件有無松動、移位及塑料件和活動件磨損情況，檢查彈簧拉力（集電器電刷與導軌的接觸壓力應保持一定壓力（見下表）。發現問題及時處理。
2, the collector: at least quarterly check once a. Focus on examination of the fastener without loosening, displacement and plastic parts and moving parts wear, check the spring tension (contact pressure collector brush and guide should maintain certain pressure (see table below). Found problems in a timely manner.
3、 連接件：至少每年檢查一次。重點檢查緊固螺栓、焊縫及支撐件是否松動、銹蝕、移位等，發現問題，及時處理。
3, connection: at least once a year to check. Focus on examination of the fastening bolts, welds and support is loose, corrosion, shift, found the problem, timely treatment.
4、 日常檢查：重點檢查軌道的平直度有無明顯偏差（大于20mm）、錯位，絕緣保護件有無脫落、斷裂、破損，不銹鋼“v"型槽有無翹起；軌道上有無異物及導電粉塵等。必要時應檢測其絕緣電阻是否符合要求（相間絕緣電阻應≥5MΩ）。 特別對行車軌道重合度、軌距、傾斜度等偏差較大，使用頻繁、車間粉塵過大、溫度較高及有水、酸、堿、霧和室外使用的環境，必須加強日常檢查與維護。
4, the daily inspection: inspection of key rail straightness has no significant deviation (more than 20mm), dislocation, insulation protection piece off, fracture, damage, stainless steel "V" type groove is not tilted orbit; there is no foreign body and conductive dust etc.. When necessary, to detect the insulation resistance is required (interphase insulation resistance should be greater than or equal to 5M.). Especially on large track gauge, coincidence degree, gradient error, use frequently, workshop dust is too large, high temperature and water, acid, alkali, fog and outdoor environment, must strengthen the routine inspection and maintenance.
