2、。它們相對(duì)獨(dú)立,是一種理想的工作崗位運(yùn)輸裝置,廣泛應(yīng)用于各種裝卸平臺(tái),所占空間也相對(duì)較小。BZD型立柱式懸臂起重機(jī)是在手動(dòng)基礎(chǔ)上加上電動(dòng)回轉(zhuǎn)驅(qū)動(dòng)裝置,與附著在懸臂梁上的電動(dòng)葫蘆,無論周旋轉(zhuǎn),水平運(yùn)行,還是升降運(yùn)動(dòng)完全實(shí)現(xiàn)電控,極大的降低了勞動(dòng)強(qiáng)度與工作效率。關(guān)鍵詞:立柱;懸臂;電動(dòng)葫蘆;回轉(zhuǎn)機(jī)構(gòu)畢業(yè)設(shè)計(jì)(論文)外文摘要DesignofBZD5ColumnRotaryBeamCraneAbstract:BZDtypefixedcolumncantilevercraneconsistsofanuprightpost,acantileverbeam,asu
