<p class="p">
<b><span>防爆挖掘机</span></b><b><span>的用途</span></b><b></b>
</p>
<p class="p">
<span>适用于煤矿、金属矿、非金属矿、竖井、斜井及平巷掘进中的装岩、清底以及冻土层的挖掘作业。</span>
</p>
<p class="p">
<b><span>防爆挖掘机的特点</span></b><b><span>：</span></b><b></b>
</p>
<p class="p">
<span>  与传统的人工清底相比，使用该机在大大节约人工成本的同时提高了作业效率，改善了工作环境。</span>
</p>
<p class="p">
<span>  与传统的柴油动力小型挖掘机相比，由于采用电动液压系统，因而具有节约能源、噪音低、无尾气污染、效率高的特点，更适用于井下使用。</span>
</p>
<p class="p">
<span>  操作者处于驾驶室保护下作业，有利于安全生产。</span>
</p>
<p class="p">
<span>  该机结构紧凑、外型尺寸小，分装部件小，便于垂直下井使用。</span>
</p>
<p class="p">
<span>采用最小回转结构，当机体上车回转时其尾部也不会超出车宽，因此更适用与井下狭小空间作业。</span>
</p>
<p class="p">
<span>电动液压挖掘机</span>SKD系统具有以下特点SKD-55型电动挖掘机液压系统采用了CLSS系统，即闭式中心负载感应系统。它是通过斜盘试变量柱塞泵斜盘倾角的方式，以减小电动机负载节能系统。作业时，由于
