1,、重慶升降平臺傳動軸的軸承連接緊固件松動,，造成抖顫，應(yīng)檢查傳動軸連接件的緊固情況,，若發(fā)現(xiàn)松動,，應(yīng)擰緊。
Hangzhou freight elevator shaft bearing connection fasteners loose, causing tremors, check fastening driveshaft connection, if found loose, should be tightened.

2,、升降平臺傳動軸的軸承損壞,，引起抖顫，應(yīng)檢查曲臂式高空作業(yè)車傳動軸的平衡塊是否脫落,，或脫落,，應(yīng)重新加平衡塊并進行平衡試驗，檢查液壓升降平臺傳動軸十字軸的軸承是否損壞,，若十字軸軸承損壞,，不僅導(dǎo)致抖顫而且還會產(chǎn)生異響，應(yīng)更換十字軸軸承,。
Hangzhou freight elevator shaft bearing damage, causing tremors, check crank shaft mounted aerial platforms block is off balance or off, should be re-added to the balance weight and balance test,check the hydraulic lifting platform cross shaft drive shaft bearings damage, if cross shaft bearing damage, not only to produce but also lead to tremors abnormal sound, replace the cross shaft bearings.

3,、傳動軸平衡塊脫落,，運轉(zhuǎn)不平穩(wěn)引起的抖顫，應(yīng)檢查中間支承情況,，如支架是否松動,，軸承是否損壞，必要時予以修復(fù)或更換,。
Hangzhou freight elevator balance weight off the shaft, causing the tremors running smoothly, you should check the intermediate support cases, such as a stent is loose, if the bearing is damaged,be repaired or replaced if necessary.
