LF70 Surface Coring Fly Drill Technical Overview Brochure

LF™70 SurFace coring FLy driLLTechnical Overview Copyright © 2011 Boart Longyear. All rights reserved.LF™70 diamond core FLy driLLMobilityThe LF™70 modular design consists of seven sections that are heliportable for reaching remote locations. This drill reduces downtime when mobilizing between sites and significantly decreases the environmental impact to a drill site.Modular DesignWith just seven components, it takes less than one hour to pull down the rig and the same amount of time to reassemble it. LightweightSpecial attention was given to the overall weight and dimension of the drill’s design. Each of its seven components weigh less than 585 kg and are easily transportable by helicopter. The LF70 is ideal for drilling in confined, remote locations. For more information on the LC™70 scan with a QR code reader on your smart phone. Copyright © 2011 Boart Longyear.
