CZM

CZM LR65

The LR65 is part of CZM’s Long Reach series and is mounted on a Cat® 323 Next Gen with variable undercarriage. It has a special designed boom with 2 lift cylinders which allows for a higher torque and crowd force to be applied to the tool, which aligned with interlocking Kelly bars makes it efficient on rock and hard soil drilling. Round Friction bars are also available for high production on softer soils. The long reach configuration makes it ideal to applications such as sound bearing walls, transmission lines and utilities, drilling on a steep slopes, and difficult to reach holes.
