About the CR25
Reliability; Robustness and Productivity
The CR25 is the ideal response to market needs, the target required of CZM’s expert designers were to obtain an advanced drilling rig that stands out from competitors.
Therefore, it was designed with the clear idea of being the evolution of technology for micropile drilling machines.
It turns out to be a drilling rig with “imposing” shapes, maintaining fast and precise mobility, equipped with a powerful engine which, thanks to the power management system (PMS) and the optimization of the hydraulic system, obtains the ideal use of engine power, reducing fuel consumption by up to 30% and guaranteeing very high productivity.
The innovative servo-assisted proportional hydraulic circuit and the high hydraulic oil flow guarantee flexibility in the equipment for installing different types of rotary heads and rotary drifters, including double rotary, and always guarantee the declared power without performance reductions.
In addition to its larger dimensions, all parts are made in high-yield strength Weldox steel.
Double boom cylinders ensure safety and efficiency also in more challenging articulation positions.
The Front of the Wall guarantees a continuous movement of +/- 93°.
The Mast is modular and built with high-yield strength Weldox steel, guaranteeing extreme safety in all working positions.
- Easy to modulate, crowd-pull-back system is integrated into the base mast and has a maximum pull-back force of 18t (39,600 lbs).
- Sliding Clamps with 1000mm (3ft 3in) stroke and pull-back force of 20t (44,000 lbs) can install double or triple clamps with a maximum diameter of 18.”
310HP engine equipped with PMS for reducing fuel consumption and emissions.
- Full Load Sensing power system operates the hydraulic system according to the drilling requirements to decrease maximum consumption by maximizing system efficiency.
- 11” touch screen for all machine setting operations.
In the design phase, particular attention was paid to the machine’s stability both during translation and during the drilling phase, above all during the execution of tie-backs with the mast transversal to the undercarriage.
A generous over-dimensioning of the structural parts, and the telescopic expandable tracks, guarantee safety and maneuverability, even with lattice extensions for the execution of Jet Grouting injections for useful depths of 30 m (98 ft) during translation, positioning and operation movements.
The electronic system allows you to manage the entire control of the machine itself, for example:
- General telematics
- Fault diagnosis
- Maneuvering speed customization
- Active security
- Passive safety
- Remote real-time control
- Remote control management
The machine is managed entirely by the latest generation Radio Command with a color display.
