液壓(ya)千(qian)斤頂(ding)(ding)和螺旋(xuan)千(qian)斤頂(ding)(ding)是兩款比較常(chang)見的(de)千(qian)斤頂(ding)(ding)，它們同(tong)樣具備強悍的(de)起重負載能力，但是在使(shi)用(yong)(yong)姿勢的(de)選擇(ze)上卻(que)存(cun)在一些差異，螺旋(xuan)千(qian)斤頂(ding)(ding)橫用(yong)(yong)豎用(yong)(yong)都會沒有問題(ti)的(de)，而液壓(ya)千(qian)斤頂(ding)(ding)卻(que)只(zhi)能垂(chui)直使(shi)用(yong)(yong)，這又是為(wei)什么呢？

液壓千斤頂不能(neng)橫用的原(yuan)因是因為其設計原理是利用(yong)液(ye)(ye)(ye)體(ti)(ti)(ti)的壓力來產生(sheng)力量，液(ye)(ye)(ye)體(ti)(ti)(ti)在(zai)壓力作用(yong)下(xia)會(hui)產生(sheng)流動(dong)，而液(ye)(ye)(ye)壓千(qian)(qian)(qian)(qian)斤頂(ding)(ding)的液(ye)(ye)(ye)體(ti)(ti)(ti)流動(dong)方向(xiang)(xiang)(xiang)是垂(chui)直(zhi)于(yu)千(qian)(qian)(qian)(qian)斤頂(ding)(ding)的活塞方向(xiang)(xiang)(xiang)，如果橫向(xiang)(xiang)(xiang)使用(yong)液(ye)(ye)(ye)壓千(qian)(qian)(qian)(qian)斤頂(ding)(ding)，液(ye)(ye)(ye)體(ti)(ti)(ti)的流動(dong)方向(xiang)(xiang)(xiang)就會(hui)與活塞方向(xiang)(xiang)(xiang)不一致，會(hui)導致液(ye)(ye)(ye)體(ti)(ti)(ti)流動(dong)不暢，從而影響千(qian)(qian)(qian)(qian)斤頂(ding)(ding)的使用(yong)效果，甚至可能會(hui)損壞千(qian)(qian)(qian)(qian)斤頂(ding)(ding)。因此，液(ye)(ye)(ye)壓千(qian)(qian)(qian)(qian)斤頂(ding)(ding)只能垂(chui)直(zhi)使用(yong)。

螺(luo)(luo)(luo)旋(xuan)千斤(jin)頂就不(bu)(bu)一樣(yang)了(le)，螺(luo)(luo)(luo)旋(xuan)千斤(jin)頂的(de)采(cai)用(yong)的(de)是(shi)螺(luo)(luo)(luo)旋(xuan)副傳動的(de)方式，無(wu)論是(shi)橫用(yong)還是(shi)豎用(yong)，它的(de)內部結構(gou)始終不(bu)(bu)會發生改(gai)變，螺(luo)(luo)(luo)旋(xuan)傳動依(yi)然是(shi)圍繞螺(luo)(luo)(luo)桿展(zhan)開，不(bu)(bu)會受(shou)到角度改(gai)變的(de)影響，所以說螺(luo)(luo)(luo)旋(xuan)千斤(jin)頂無(wu)論是(shi)橫用(yong)還是(shi)豎用(yong)都是(shi)沒有太大區別的(de)。
