  宇雕手扳葫蘆省力原理

  手扳葫蘆是通過人力扳動(dòng)手柄借助杠桿原理獲得與負(fù)載相匹配的直線牽引力,輪換地作用于機(jī)芯內(nèi)負(fù)載的一個(gè)鉗體,帶動(dòng)負(fù)載運(yùn)行。手扳葫蘆一種輕小型理想的手動(dòng)起重工具,自重輕,工作級(jí)別高,安全性能好,工作噪音低,制動(dòng)力矩大等特點(diǎn)。河北宇雕詳細(xì)講解;手扳葫蘆的省力原理,用動(dòng)滑輪拉物體,繩子的兩邊受力是相等的,且均為所牽引物理重力的一半,而人只需要拉其中的一邊,故人只需承受物體一半的重力,而另一半的重力則由繩的另一端所固定的物體所承受。其實(shí)也就是力矩平衡的一個(gè)方法,增大力矩就可以減少力,也就是經(jīng)常所說的杠桿原理。

  宇雕手扳葫蘆特點(diǎn):

  1獨(dú)特的彈性離合器技術(shù),可在任意高度吊起貨物

  2輕盈的手拉裝置、起升率高

  3新型設(shè)計(jì)的鍛打式吊鉤,吊鉤頂端更為安全,且具有緩慢彎曲性能
