This Gardner-Denver 400 is a used vertical drill — sometimes referred to as a rotary drill rig — built for drilling operations in mining, water well, geotechnical, and similar ground-penetration applications. Gardner-Denver is a well-established manufacturer of industrial and drilling equipment, known for producing robust machinery for the mining, energy, and construction industries.
This machine is rated for the 3.5-inch to 4.5-inch class of drill string, placing it in the mid-range of vertical drilling capacity. It is powered by a CAT diesel engine and is configured as a hydraulic drill, with the hydraulic rotation system providing the torque needed for productive drilling performance. The rig is equipped with a cab and a hydraulic rod changer, offering the operator both a sheltered working environment and an automated means of adding or removing drill rods — a feature that improves both efficiency and safety during extended drilling operations.
The machine has accumulated 4,600 total hours of use. Notably, a new hydraulic rotation pump has been fitted, which is a key component in the hydraulic drive system and directly affects drilling power and reliability. This recent replacement represents a meaningful mechanical improvement to the machine's current condition.
The drill is located in Kentucky, USA, and was manufactured in 2000.
