New four-boom rig hits targets

摘要

A NEW FOUR-BOOM DRILL RIG developed by Atlas Copco, in co-operation with Nordic tunnelling contractor Veidekke, was put to work on a major railway project near Gothenburg, Sweden. The Boomer XE4 C is a fully-computerised rig designed to drill all pre-grout holes as well as blast holes. Atlas Copco and Veidekke worked together for several months on the specifications for the Boomer XE4 C, equipping the machine with high performance COP 3038 rock drills, a specially-developed automatic rod handling system - Auto RHS E - for drilling of up to 30 m long grout holes, and the Atlas Copco rig control system (RCS) enabling it to be handled by just one operator. Rig operator Niklas Karlsson said, "I think the Boomer XE4 C is a perfect solution for the work we are doing and I am convinced that this new technology will make the whole pre-grouting process much more efficient".
