This 2004 Cubex QXR920 is a used vertical drill — also known as a surface drill rig — a track-mounted, self-propelled drilling machine used for blast-hole and exploration drilling on surface mining and quarrying operations. Cubex is a recognised manufacturer of heavy rotary drilling equipment, building rigs primarily for hard-rock surface mining applications.
The machine was comprehensively rebuilt in 2019 and has accumulated 16,896 hours of total operation. Power comes from a Caterpillar CAT C15 engine, a well-regarded heavy-duty diesel unit widely used in demanding mining and construction environments. The rotary head is a Cubex unit that had logged 6,230 hours at the time of its rebuild in May 2019.
Drilling performance is defined by a rotation torque of 5,730 Nm and a variable rotation speed ranging from 0 to 80 RPM, providing broad adaptability across different ground conditions and drill-string configurations. The variable jaw rotation of 15 degrees and a clamping force of 288 kN support reliable rod handling and breakout capability during operation.
The carousel holds a maximum of six drill rods, each measuring 6 metres (20 feet) in length. The minimum rod diameter is 5 inches, with a noted rod size of 3.25 inches also specified. An onboard Sullair air compressor is included, along with GPS equipment and a complement of spare parts.
The rig is located in Queensland, Australia, and is offered in used condition at A$216,404.
