Designed to improve efficiency and deliver dependable penetration for the mines, the Sandvik DR416i delivers a single-pass capacity of 21 m/69 ft, the longest single-pass mast in its class. Constructed for large-diameter (406 mm/16 in) rotary drilling, the Sandvik DR416i is automation-ready, scalable, and supplies the highest rotational torques and pulldown forces at the lowest possible operating cost. It’s also equipped with the patented Compressor Management System (CMS), designed to reduce fuel consumption and improve productivity.
Sandvik said the three key principles that led the innovative design efforts that brought the Sandvik DR416i to life are safety, productivity and value. “We continue to enhance our product offering to provide exceptional value to our customers,” said Dave Shellhammer, president, Rotary Drilling Division, Sandvik Mining and Rock Technology. “In developing the latest addition to our iSeries family, we looked at our customers’ greatest challenges in the large-diameter drill space and developed a cost-effective, highly efficient solution to solve those challenges.”
The blueprint for the Sandvik DR416i is focused on space, accessibility, visibility and automation to ensure operator safety, including the following features easy-access 360° walkways, four egress points, easy access to mast components and non-rust fiberglass reinforced grating. Sandvik expects the DR416i to achieve optimal availability and productivity through features such as dual-feed speeds for greater drilling control and faster retract, auto-setup, a “Live Tower” design, and a traveling centralizer for straighter holes and reduced drill pipe wear.
