　　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
