CZM Introduces CR25 Micropile Machine to Fleet
The CR25 is an advanced Micropile drilling machine designed to perform micro piles, tie-backs, or jet grouting on tough soil conditions. With 28,122 kg of operation weight, it is one of the largest Micropile machines in the market. The extendable undercarriage makes it very stable, especially with large diameter micro piles on long mast configuration. The machine is fully articulated, allowing it to perform tiebacks in various positions. The articulation is extremely robust, with double boom cylinders, and all the parts are manufactured with high-yield Weldox Steel. It has front-of-the-wall kinematics, allowing it to drill parallel to the tracks. The crowd/pull-back system is integrated into the base mast with a maximum force of 176.5 kN, driven by a motor reducer and chain with an automatic tensioner. With a maximum stroke of 10.49 m, it can work with long sections of drilling rods. The CR25 comes with double or triple clamps and sliding clamps as a standard feature, with 100 cm of stroke and 195.7 kN of pull-back force, making it easier to break casing connections. The power pack has a 310 hp Cummins B6.7 equipped with PMS for reducing fuel consumption and emissions. It is fitted with a complete load-sensing hydraulic system designed for efficient operation, reducing fuel consumption by up to 30% and guaranteeing very high productivity. The machine can be equipped with a single or double rotary with or without a drifter. The standard rotary has 32 kNm of torque, a maximum speed of 168 rpm, and a 114 mm passage. The CR25 is the response to market needs and stands out among competitors for its power, reliability, robustness, stability, and safety. CZM Foundation Equipment offers a comprehensive line of drilling rigs engineered for various foundation applications, manufactured in the U.S. at its 7,000 m2 facility near Savannah, Georgia. Its machines are available for sale and rent throughout North America.
