1、升降货梯http://www.jntr168.com/机构上、下台面的滚轮磨损变形严重或表面平滑度差，导致滚轮在导向槽里移动时产生噪音大或液压升降平台晃动。主要原因有滚轮加工精度不够，表面光滑度差；滚轮没有经过热处理，硬度不够；导向槽表面粗糙，光滑度差，加剧了滚轮磨损。出现这种情况，应更换合格的滚轮，如果导向槽表面粗糙，也应多导向槽的表面进行处理。
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、升降货梯由于长时间缺乏润滑油运行，滚轮轴承损坏，导致滚轮在移动式产生振动或较大的噪音。处理方法很简单，更换滚轮轴承即可。
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、升降货梯各支臂或支杆连接的轴套或轴由于长时间缺乏润滑油导致液压升降平台升降时噪音变大，在这种情况下，可以加注润滑油，如果加润滑油仍不起作用，则要检查各个轴套或轴的磨损状况，如果磨损严重，则需要更换轴套或轴。
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、升降高度较高的升降货梯http://www.jntr168.com/含有导轨时，如果导向轮或侧向轮的轴承损坏，在升降过程中，导向轮与导轨摩擦时也会产生刺耳的噪音。出现这种情况，可以更换磨损严重的导向轮轴承。
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.
