CZM LR125 Drilling Rig

Long reach drilling rig mounted on CAT 336 Next Gen base

The CZM LR125 is a long reach drill rig mounted on a CAT 336 Next Gen base. It has a specifically designed boom with 2 lift cylinders for higher torque and crowd force to be applied to the tool. This boom aligned with an interlocking kelly bar makes this machine efficient for drilling through rock and hard soil. Round friction bars are available for high production on softer soils. The long reach configuration is ideal for applications such as sound bearing walls, transmission lines, utilities, drilling on steep slopes, and difficult to reach holes. Features include automatic gear shifting between 3 operating speeds for seamless operation and high production plus automatic down the hole winch stop. The drill is equipped with CAT Vision Link to monitor the machine remotely.
