CD1、MD1型鋼絲繩電動(dòng)葫蘆是一種輕小型起重設(shè)備。它可以安裝在電動(dòng)單梁起重機(jī)、橋式起重機(jī)、門(mén)式起重機(jī)、懸臂起重機(jī)上。稍加改動(dòng)，還可作卷?yè)P(yáng)機(jī)用。因此，它是工廠、礦山、港口、貨場(chǎng)、商店等常用的起重設(shè)備之一，是提高勞動(dòng)效率，改善勞動(dòng)條件的必備機(jī)械。
　　CD1型電動(dòng)葫蘆的起升速度為常速，可以滿足一般使用要求；MD1型電動(dòng)葫蘆具有兩種起升速度—常速和慢速。慢速工作可以滿足精密裝卸，砂箱合模，機(jī)床檢修等精細(xì)作業(yè)的要求。所以，MD1型電動(dòng)葫蘆的適用范圍比CD1型電動(dòng)葫蘆更為廣泛。
　　A Brief Introduction
　　Model CD1 、MD1 Wirerope Electric Hoist is a small-sized lifting equipment,which can be mounted on single beam, bridge, gantry and cranes,with slight modificdtion,it can also be used as a winch, It is widely used in factories, mines,harbours,warehouses,cargo storage areas and shops,essential in raising  working efficiency and improving working conditions.
　　Model CD1 Electric Hoist has only one normal speed,which can satisfy normal appiication,Model MD1 Electrc Hoist provides two speed ,normal speeed and low speed .At a low speed, it can do precise loading and unlading, mounding of
　　Sand box ,mainntenace of machine tools, etc. This Model MD1 Electric Hoist is more widely than Modrl CD1.
