殘疾人升降機(jī)進(jìn)行作業(yè)的時(shí)候，會(huì)出現(xiàn)螺栓出現(xiàn)松動(dòng)的現(xiàn)象，給機(jī)器設(shè)備帶來很大的安全的隱患，這到底是怎么回事呢？
1、殘疾人升降機(jī)的螺栓，它通常是會(huì)有一定的預(yù)緊力，但是在實(shí)際安裝過程中，不可能達(dá)到規(guī)定的預(yù)緊力要求，在這種情況下，只要有其他力的作用，螺栓就很容易松動(dòng)了。
Fixed lift bolts, it is usually there will be some preload, but in the actual installation process, it is impossible to achieve the requirements set preload, in this case, as long as there are other force, the bolt is very easy to loose.
2、殘疾人升降機(jī)在上升、旋轉(zhuǎn)過程中，螺栓的受力會(huì)因此而發(fā)生變化，一旦這種變化超過一定范圍時(shí)，就有可能使得螺栓松動(dòng)。
Fixed lift rise, during rotation, force the bolt will therefore change, once the change exceeds a certain range, it is possible so that bolts loose.
3、殘疾人升降機(jī)必須的要進(jìn)行定期的檢查，注以各個(gè)連接部位螺栓的緊固情況，為設(shè)備的安全運(yùn)行提供有力的保障。
Fixed lift must be regularly checked, note fastening bolts to various joints, to provide effective protection for the safe operation of the equipment.
