升降貨梯基本上都是采用鋼材，長時間不使用有些關節部位都會生銹，升降貨梯生銹之后使用起來很不方便，升降速度嚴重變慢，再次使用時肯定沒有以前靈活，而且放在室外的，接觸過雨水腐蝕，表面的防銹漆也會掉，生銹的表面會很丑，但是內部都不壞，要是就這樣不用扔掉難免會浪費，面對這樣的問題我們應該如何處理呢？
  
首先在升降貨梯的關節部位加上潤滑液，液壓油選擇上好的進行更換，外觀在掉漆的地方先去銹然后補上防銹漆，漆的顏色要和本身原來顏色相同。這些都只是針對銹的不嚴重的，如果生銹實在太嚴重了，內部零件都基本受損那就沒有再次補救的意思了，只能重新更換了，所以升降貨梯不要長時間放著不使用，每年也要注意保養。
First add the joints in cargo lifter lubricating fluid, hydraulic oil and replace good choice, look at where to go to rust and paint chips fill the rust, paint colors and itself to be the same as the original color. These are just against rust is not serious, if rust is too serious, it would damage the internal parts are basically meant no remedy again, only to be replaced, so the cargo lifter not long stood not in use, Note also that the annual maintenance.  

升降貨梯的整個防護措施也要由專門人士來進行保養，生銹之后很多人都是自己再關節部位加油之類的，但是內部零件都無法更換了，所以還是要專業的人來才能更好的整修。
Cargo lifter entire protective measures should be carried out by a professional maintenance, rusty after a lot of people are their own and then filling the joints and the like, but the internal parts can not be replaced, so we should be professional people in order to better renovations.
