      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載相匹配的直線牽引力,輪換地作用于機芯內負載的一個鉗體,帶動負載運行。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,可在任意高度吊起貨物

        2輕盈的手拉裝置、起升率高

        3新型設計的鍛打式吊鉤,吊鉤頂端更為安全,且具有緩慢彎曲性能
