This Atlas Copco T4BH is a used vertical drill — sometimes referred to as a drill rig or rotary drill — a type of machine used in mining, quarrying, water well drilling, and geotechnical applications to bore vertical holes into rock and earth. Atlas Copco is a well-established Swedish industrial equipment manufacturer with a long history of producing drilling and mining machinery, compressed air equipment, and related tools for heavy industry worldwide.
Power comes from a Cummins QSX15 Tier 4 diesel engine, a large-displacement, emissions-compliant powerplant well suited to demanding drilling environments. The machine logs 1,070 hours at an HR2.5 rating and is equipped with an EARS system. The drill head is a two-motor spur gear configuration, providing the rotary force needed to drive drill rod into the ground, and it features an auto-lube system to reduce maintenance demands and protect drivetrain components during operation.
The drill is set up for 5-inch by 25-foot drill rod, and rod handling is managed by a five-rod carousel, allowing the operator to add and cycle rod without manual intervention at the mast. A Formost cushion sub is fitted to help absorb shock and protect both the drill string and the head during percussion drilling. A 4,000-pound winch is included for lifting and positioning tasks at the mast.
Dust control is handled by a Tipton FC3600 dust collector, which captures cuttings and airborne particulate at the hole collar — an important feature for regulatory compliance and operator safety. A hammer lubricator is also fitted to keep the down-the-hole or top-hammer percussion components properly lubricated during operation. This 2014 machine is located in Kentucky, USA.
