瑞典Atlas Copco公司的潜孔钻车开发较早,品种也较多。所谓潜孔钻车就是在钻车上配用潜孔冲击器和回转器,进行潜孔凿岩作业。它的突出特点是;钻凿炮孔的方位可以进行多方面调节,以适应各种施工工程的要求。该公司的潜孔钻车有:ROC301、ROC304、ROC306、ROC601、ROC604、ROC606、ROC403A、ROC404A、ROC405A等。这些产品都是气动潜孔钻车,它们均配用气动回转器。还有一些属于气动液压潜孔钻车,如ROC433H、ROC434H、ROC435H等。它们都是配用液压回转器和气动潜孔冲击器。另外,ROC306型潜孔钻车是用于井下高梯段采矿。与潜孔钻车相适应的用于驱动钻具回转的回转器,该公司不仅已经形成了气动和液压的两个系列产品,而 Sweden Atlas Copco’s DTH drilling development earlier, more varieties. The so-called DTH hole drilling rig is equipped with a drill hole in the hole impactor and gyrator, hole drilling operations. Its salient features are: Drilling hole orientation can be adjusted in many ways to meet the requirements of a variety of construction projects. The company’s deep hole drilling vehicles are: ROC301, ROC304, ROC306, ROC601, ROC604, ROC606, ROC403A, ROC404A, ROC405A and so on. These products are all Pneumatic DTH rigs, all equipped with pneumatic gyroscopes. There are also some belonging to the pneumatic hydraulic hole drills, such as ROC433H, ROC434H, ROC435H and so on. They are equipped with hydraulic rotary and pneumatic down hole impactor. In addition, ROC306 DTH drilling rig is used for downhole mining. In contrast to the downhole drill used to drive the rotary drill rotary, the company has not only formed a series of pneumatic and hydraulic products, and
