        宇雕手扳葫蘆省力原理

          宇雕手扳葫蘆省力原理

          手扳葫蘆是通過人力扳動手柄借助杠桿原理獲得與負(fù)載相匹配的直線牽引力,輪換地作用于機芯內(nèi)負(fù)載的一個鉗體,帶動負(fù)載運行。手扳葫蘆一種輕小型理想的手動起重工具,自重輕,工作級別高,安全性能好,工作噪音低,制動力矩大等特點。河北宇雕詳細(xì)講解;手扳葫蘆的省力原理,用動滑輪拉物體,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。其實也就是力矩平衡的一個方法,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:

          1獨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)計的鍛打式吊鉤,吊鉤頂端更為安全,且具有緩慢彎曲性能
