升降货梯基本上都是采用钢材，长时间不使用有些关节部位都会生锈，升降货梯生锈之后使用起来很不方便，升降速度严重变慢，再次使用时肯定没有以前灵活，而且放在室外的，接触过雨水腐蚀，表面的防锈漆也会掉，生锈的表面会很丑，但是内部都不坏，要是就这样不用扔掉难免会浪费，面对这样的问题我们应该如何处理呢？
  
首先在升降货梯的关节部位加上润滑液，液压油选择上好的进行更换，外观在掉漆的地方先去锈然后补上防锈漆，漆的颜色要和本身原来颜色相同。这些都只是针对锈的不严重的，如果生锈实在太严重了，内部零件都基本受损那就没有再次补救的意思了，只能重新更换了，所以升降货梯不要长时间放着不使用，每年也要注意保养。
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.  

升降货梯的整个防护措施也要由专门人士来进行保养，生锈之后很多人都是自己再关节部位加油之类的，但是内部零件都无法更换了，所以还是要专业的人来才能更好的整修。
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.
