<p>The Darda WIDA AB C20-T4 combines a Wimmer AB2300 T4 rotary hammer drill with a machine-guided Darda C20 splitting cylinder on one carrier-mounted rig, so a single machine drills the hole and splits the rock without repositioning or swapping attachments. Every drilling function – feed, rotation, percussion – is proportionally controlled and infinitely adjustable from a radio remote, with PLC drilling automation, depth measurement, and anti-jamming and adjustable-cavity automation built in. A dedicated alternator powers the control electronics independently of the excavator’s own hydraulics, and the remote displays live angle measurement on both the X and Y axis so the operator can hold true alignment through the whole cycle. Built for compact and tunnel excavators above 15 t lifting capacity, with cross-sections from 11 ft 6 in (3.5 m).</p><ul><li>2-in-1 rig: drills and splits without repositioning</li><li>Wimmer AB2300 T4 rotary hammer drill, WHL300 hammer, 76 mm max drillhole</li><li>Machine-guided Darda C20 splitting cylinder, up to 1,800 t splitting force</li><li>Radio remote control – proportional, infinitely adjustable, with X/Y angle display</li><li>PLC drilling automation with depth measurement, anti-jamming and adjustable-cavity control</li><li>Dedicated alternator powers control functions independent of carrier hydraulics</li></ul>
