1、軸承過熱，產生的原因是缺油，油中含雜質，油孔堵塞；接觸不良或軸線不同心；間隙過??；油圈轉動不靈或卡住。這時應該清洗、加油或換油，通油孔；調整；加墊或刮研；調整或更換油圈。
Bearing overheating causes are lack of oil, oil containing impurities, hole blockage; bad or different from the central axis; gap is too small; Oil circle rotation not working or stuck. At this point should be cleaned, fuel or oil change, through hole; adjustment; padded or scraping; adjust or replace the oil ring.
2、升降平臺滾筒輪毅松動，產生的原因是局部受力過大，連接件松動或斷裂，處理的方法是緊固或更換連接件。
Yi loose roller wheel lifting platform, causes localized force is too large, loose connections or broken. Treatment methods are tightening or replacing connectors.
3、升降平臺滾筒有異聲，產生的原因是連接桿件松動或斷裂，產生相對位移和振動；焊縫開裂；筒殼強度不夠，產生變形；襯套與軸徑磨損，間隙過大；聯軸器松動。處理的方法是緊固或更換、補焊、筒內補焊加強筋；換襯套，加強筋潤滑；緊固或更換損壞零件。
Lifting platform drum has a different sound, the cause is loose or broken connecting rod, the relative displacement and vibration; weld cracking; tube shell strong enough to produce distortion;bushing and shaft wear, the gap is too large; couplings loose. Treatment methods are tightened or replaced, welding, tube welding ribs; changing bushings, ribs lubrication; tighten or replace damaged parts.
