升降貨梯http://tel4008.com/進(jìn)入冬季后容易出現(xiàn)一些小問題和小故障，使用者對升降機進(jìn)行冬季保養(yǎng)和維護(hù)時要多加注意，更要講究一定的方法，下面濟(jì)南天銳升降機械的有關(guān)專家就給大家介紹一下升降貨梯冬季如何保養(yǎng)？

1、升降貨梯液壓油夏季與冬季是使用不同種類的，在低溫下，夏季用的液壓油會變得黏稠，甚至凍住。進(jìn)入冬季低溫后，一定要記得更換冬季使用含有防凍劑的液壓油，這種油適合低溫下作業(yè)。
Cargo lifter hydraulic oil summer and winter is to use different types of, at low temperature, hydraulic oil used in the summer to become sticky, even frozen. After entering the winter temperature, we must remember to replace the use of hydraulic oil contains antifreeze in winter, and this oil suitable for low temperature operation.

2、升降貨梯http://tel4008.com/鋼材在低溫下，會有明顯的熱脹冷縮效應(yīng)，雖然設(shè)計制造升降貨的時候都會將鋼材這種性質(zhì)考慮進(jìn)去，但是畢竟所處的環(huán)境不同，在極度低溫的條件下，鋼材會出現(xiàn)一些不穩(wěn)定的表現(xiàn)，如硬度增加，韌性下降等，這個時候就需要多注意維護(hù)設(shè)備，使關(guān)鍵部位保持潤滑，以免出現(xiàn)干磨的現(xiàn)象。
Cargo lifter steel at low temperatures, there will be significant expansion and contraction effect, although design and manufacture of lifting the goods when the steel of this nature will be taken into account, but are different from the environment, in extremely low temperatures, the steel will some unstable performance, such as increased hardness, toughness decline, this time on the need to pay more attention to maintenance of equipment, key parts maintain lubrication to avoid the phenomenon of dry grinding.
