This Gefco SS70K is a used vertical drill — sometimes called a rotary drill rig — built in 1982 and currently located in Utah, USA. Vertical drills of this type are designed for deep-hole drilling applications including water well, geotechnical, and resource exploration work. Gefco is a recognised American manufacturer of drilling equipment, with a long history of building truck-mounted and self-propelled drill rigs for the water well and environmental drilling industries.
The machine is powered by a Detroit 8V92T engine that has been rebuilt, paired with a 13-speed Fuller transmission, providing a robust and well-matched drivetrain for demanding field conditions. The mast stands 42 feet high and is rated for a 100,000-pound capacity, giving the rig the structural backbone needed to handle heavy drill strings at depth.
The drawworks and main winch deliver 70,000 pounds of pullback capacity operating on a four-line block arrangement, while an auxiliary winch adds a further 10,000 pounds of lifting capacity for secondary handling tasks. The top drive unit produces 100,000 inch-pounds of torque across a speed range of 0 to 100 RPM and is fitted with a 3-inch water course for fluid circulation; the seller notes it has been partially rebuilt. A single-joint rod loader is included, streamlining the process of adding and handling drill pipe during operations.
An optional 6-inch side-inlet swivel for reverse circulation drilling is available at additional cost, expanding the rig's capability for applications where reverse circulation methods are preferred. This unit is priced at $387,500.
