1、<\/span>MG型<\/span>雙梁吊鉤門式起重機<\/span>由橋梁、大車運行機構、小車、電氣設備組成<\/span>，<\/span>大車運行機構采用分別驅(qū)動<\/span>，<\/span>全部機構均在操縱室內(nèi)操縱<\/span>；<\/span><\/span> <\/p>

2、<\/span>根據(jù)主梁結(jié)構不同，又可分為箱形梁和桁架兩種形式。一般多采用箱形結(jié)構<\/span>，<\/span>大小車運行機構采用三合一減速機，方便維護。<\/span><\/span> <\/p>

3、<\/span>雙主梁門式起重機<\/span>具<\/span>有<\/span>大風報警、防斷軸、防傾翻等各種安全措施<\/span>，承<\/span>載能力強，跨度大、整體穩(wěn)定性好，品種多，但自身質(zhì)量與相同起重量的單主梁門式起重機相比要大些，造價也較高<\/span> <\/span>；<\/span><\/span> <\/p>

3、<\/span>該<\/span>起重機是一種雙軌運行的起重機<\/span>，<\/span>工作環(huán)境溫度-25～40℃。適用于工廠企業(yè)、車站、碼頭、建筑工地、水電站、和造船等作業(yè)場所吊運貨物<\/span>；<\/span><\/span> <\/p>

4、<\/span>起重機導電形式分為電纜和滑觸線兩種，訂貨時任選一種。選用本起重機時須填寫訂貨規(guī)范表，須注明使用時工作環(huán)境的**溫度和**溫度以及電源等。<\/span><\/span> <\/p>
