QL-K液压扩张器是根据石材开采的特点设计的一种新型矿山**机械，主要用于大块石料的移动，翻倒作业，大大简化了原有的作业方式。

    岩石的抗压强度大，搞拉强度小，充分利用这两种之间的差异，大大提高了岩石开采的效率和降低了成本，从而达到事半功倍的效果。

  QL-K hydraulic expansion is based on the characteristics of stone mining, a new design for mine machinery, large stone used mainly for the mobile, overturned operations, greatly simplified the original practices. the compressive strength of rock, Tensile Strength engage in small, fully utilize the difference between the two is a much more rock mining efficiency and reduce costs. in order to achieve effective and efficient.
