1、升降貨梯http://www.it616.com.cn/機構上、下臺面的滾輪磨損變形嚴重或表面平滑度差，導致滾輪在導向槽里移動時產生噪音大或液壓升降平臺晃動。主要原因有滾輪加工精度不夠，表面光滑度差；滾輪沒有經過熱處理，硬度不夠；導向槽表面粗糙，光滑度差，加劇了滾輪磨損。出現這種情況，應更換合格的滾輪，如果導向槽表面粗糙，也應多導向槽的表面進行處理。
Cargo lifter mechanism on the wheel under the table wear severely deformed or surface smoothness is poor, resulting in a large wheel noise or hydraulic lifting platform shaking moves in the guide slot. The main reason there is not enough precision rollers, smooth surface is poor; the wheel has not been heat-treated, hardness is not enough; a guide groove surface roughness, smoothness is poor, exacerbated wheel wear. This happens, replace qualified wheel, if the guide groove surface roughness, the surface should be treated more groove-oriented.
2、升降貨梯由于長時間缺乏潤滑油運行，滾輪軸承損壞，導致滾輪在移動式產生振動或較大的噪音。處理方法很簡單，更換滾輪軸承即可。
Cargo lifter run due to lack of lubricant, wheel bearing damage long time, resulting in a larger wheel vibration or noise in a moving ceremony. Processing method is very simple, you can replace the wheel bearings.
3、升降貨梯各支臂或支桿連接的軸套或軸由于長時間缺乏潤滑油導致液壓升降平臺升降時噪音變大，在這種情況下，可以加注潤滑油，如果加潤滑油仍不起作用，則要檢查各個軸套或軸的磨損狀況，如果磨損嚴重，則需要更換軸套或軸。
Each cargo lifter arm or strut connecting sleeve or shaft due to prolonged lack of lubrication is causing the noise becomes large when the hydraulic lift platform lift, in this case, you can add oil, add oil if still does not work will have to check the wear condition of each sleeve or shaft, if badly worn, replace the bushings or shaft.
4、升降高度較高的升降貨梯http://www.it616.com.cn/含有導軌時，如果導向輪或側向輪的軸承損壞，在升降過程中，導向輪與導軌摩擦時也會產生刺耳的噪音。出現這種情況，可以更換磨損嚴重的導向輪軸承。
When the height of the higher cargo lifter contain rails, or if the guide wheel side wheel bearing damage in the lifting process, will produce harsh noise when the guide wheel and rail friction. This happens, you can replace badly worn guide wheel bearings.
