CZM Foundation Equipment has introduced the LR75 drill rig to its expanding fleet. 

The long reach series is a unique CZM design that matches the performance of the company’s EK line to a boom mounted set up with increased reach. 

The long reach machines are equipped with a specially designed boom with two lift cylinders, allowing for higher torque and crowd force to be applied to the tool. This 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 LR75 is the medium size model of CZM’s long reach series mounted on a Cat 330 Next Gen base with variable undercarriage.  Highlights of this machine include 275 hp, 77,530-foot pounds of torque, a maximum drilling diameter of 3.35 metres, a standard drilling depth of 18.2 metres, main winch line pull of 12,301 kg with two gears for high speed and pulling force, and operation weight of 41,730 kg. 

The rotary offers three operation and spinoff speeds and automatic gear shifting. Its maximum reach of 3.83 metres is ideal for applications such as sound bearing walls, transmission lines and utilities, substations, drilling on steep slopes and difficult to reach holes. 

The LR75 can be transported in one load, with the Kelly bar attached. As well, the machine is easy to set up without the need of any support equipment. 

It is also equipped with the CZM control system to monitor drilling parameters, perform some functions automatically and to help with diagnostics and maintenance records. 

CZM is also able to remotely view telematics information to troubleshoot and resolve issues.
