Atlas Copco's generation of ROC surface crawlers raises the quality of rock drilling to a new level. The lowest cost per ton of rock produced comes from the higher productivity; straighter holes and better overall economy designed into the ROC series. These surface crawlers include several models that are ideally suited for bench drilling. Choose between hydraulic top-hammer, Atlas Copco's patented COPROD® system, or down-the-hole drilling methods. The ROC series of crawlers are setting new standards for stability, maneuverability and safety in quarries and contracting work.
