The long reach machines are equipped with a specially designed boom with two lift cylinders allowing for a higher torque and crowd force to be applied to the tool, which aligns with interlocking Kelly bars making it efficient in rock and hard soil drilling. Round friction bars are also available for high production in softer soils.
The LR65 is the smallest model of CZM's long reach series mounted on a CAT323 base. Highlights of this machine include 164hp, 67,150ftlbs of torque, maximum drilling diameter of 9ft, standard drilling depth of 40ft, main winch line pull of 27,120lbs with two gears for high speed and pulling force and operation weight of 80,000lbs.
The rotary offers three operation and spinoff speeds and automatic gear shifting. Its maximum reach of 10ft 3in is ideal for applications such as sound bearing walls, transmission lines and utilities, substations, drilling on steep slopes and difficult to reach holes.
This model can be transported in one load, with the Kelly bar on and is easy to set up, without the need of any support equipment. It is also equipped with CZM's control system to monitor drilling parameters, perform some functions automatically and to help with diagnostics and maintenance records. We can also log in remotely to its telematics system to troubleshoot and resolve issues.
