按照鏟斗來分，挖掘機(jī)又可以分為正鏟挖掘機(jī)、反鏟挖掘機(jī)、拉鏟挖掘機(jī)和抓鏟挖掘機(jī)。正鏟挖掘機(jī)多用于挖掘地表以上的物料，反鏟挖掘機(jī)多用于挖掘地表以下的物料。1.反鏟挖掘機(jī)反鏟式是我們見過最常見的，向后向下，強(qiáng)制切土?？梢杂糜谕C(jī)作業(yè)面以下的挖掘，基本作業(yè)方式有：溝端挖掘、溝側(cè)挖掘、直線挖掘、曲線挖掘、保持一定角度挖掘、超深溝挖掘和溝坡挖掘等。2.正鏟挖掘機(jī)正鏟挖掘機(jī)的鏟土動(dòng)作形式。其特點(diǎn)是“前進(jìn)向上，強(qiáng)制切土”。正鏟挖掘力大，能開挖停機(jī)面以上的土，宜用于開挖高度大于2m的干燥基坑，但須設(shè)置上下坡道。正鏟的挖斗比同當(dāng)量的反鏟的挖掘機(jī)的斗要大一些，可開挖含水量不大于27%的一至三類土，且與自卸汽車配合完成整個(gè)挖掘運(yùn)輸作業(yè)，甘肅反鏟挖機(jī)，還可以挖掘大型干燥基坑和土丘等，甘肅反鏟挖機(jī)。正鏟挖土機(jī)的開挖方式根據(jù)開挖路線與運(yùn)輸車輛的相對(duì)位置的不同，甘肅反鏟挖機(jī)，挖土和卸土的方式有以下兩種：正向挖土，側(cè)向卸土；正向挖土，反向卸土。

style="text-indent:25px">更新設(shè)計(jì)理論，提高可靠性，延長(zhǎng)使用壽命。美、英、日等國(guó)家推廣采用有限壽命設(shè)計(jì)理論，以替代傳統(tǒng)的無限壽命設(shè)計(jì)理論和方法，并將疲勞損傷累積理論、斷裂力學(xué)、有限元法、優(yōu)化設(shè)計(jì)、電子計(jì)算機(jī)控制的電液伺服疲勞試驗(yàn)技術(shù)、疲勞強(qiáng)度分析方法等先進(jìn)技術(shù)應(yīng)用于液壓挖掘機(jī)的強(qiáng)度研究方面，促進(jìn)了產(chǎn)品的質(zhì)量高效率和競(jìng)爭(zhēng)力。美國(guó)提出了考核動(dòng)強(qiáng)度的動(dòng)態(tài)設(shè)計(jì)分析方法，并創(chuàng)立了預(yù)測(cè)產(chǎn)品失效和更新的理論。日本制定l了液壓挖掘機(jī)構(gòu)件的強(qiáng)度評(píng)定程序，研制了可靠性信息處理系統(tǒng)。在上述基礎(chǔ)理論的指導(dǎo)下，借助于大量試驗(yàn)，縮短了新產(chǎn)品的研究周期，加速了液壓挖掘機(jī)更新?lián)Q代的進(jìn)程，并提高其可靠性和耐久性。例如，液壓挖掘機(jī)的運(yùn)轉(zhuǎn)率達(dá)到85%～95%，使用壽命超過1萬小時(shí)。</p><div

3.拉鏟挖掘機(jī)拉鏟挖土機(jī)也叫索鏟挖土機(jī)。其挖土特點(diǎn)是：“向后向下，自重切土”。宜用于開挖停機(jī)面以下的Ⅰ、Ⅱ類土。工作時(shí)，利用慣性力將鏟斗甩出去，挖得比較遠(yuǎn)，挖土半徑和挖土深度較大，但不如反鏟靈活準(zhǔn)確。尤其適用于開挖大而深的基坑或水下挖土。4.抓鏟挖土機(jī)抓鏟挖土機(jī)也叫抓斗挖土機(jī)。其挖土特點(diǎn)是：“直上直下，自重切土”。宜用于開挖停機(jī)面以下的Ⅰ、Ⅱ類土，在軟土地區(qū)常用于開挖基坑、沉井等。尤其適用于挖深而窄的基坑，疏通舊有渠道以及挖取水中淤泥等，或用于裝載碎石、礦渣等松散料等。開挖方式有溝側(cè)開挖和定位開挖兩種。如將抓斗做成柵條狀，還可用于儲(chǔ)木場(chǎng)裝載礦石塊、木片、木材等?，F(xiàn)今的挖掘機(jī)占絕大部分的是全液壓全回轉(zhuǎn)挖掘機(jī)。液壓挖掘機(jī)主要由發(fā)動(dòng)機(jī)、液壓系統(tǒng)、工作裝置、行走裝置和電氣控制等部分組成。液壓系統(tǒng)由液壓泵、控制閥、液壓缸、液壓馬達(dá)、管路、油箱等組成。電氣控制系統(tǒng)包括監(jiān)控盤、發(fā)動(dòng)機(jī)控制系統(tǒng)、泵控制系統(tǒng)、各類傳感器、電磁閥等。
