"F" is here! The XR138F low headroom rotary drilling rig is suitable for pile foundation operations with a height limit of 10 meters

Under the high-voltage power line with a height limit of 10 meters, the brand-new XCMG XR138F low-headroom rotary drilling rig, which meets the National IV emission standards, roared loudly, and the drill pipe was constantly lifted and lowered for the construction of the pipe gallery support piles.

At the construction site along the southern extension of Changchun Rail Transit Line 4, there is a high-voltage line right above the operation site. The client requires that under the condition of meeting the 10-meter height limit for construction, the depth of the rotary drilling rig should reach more than 18 meters. In addition, after the project is completed, the XR138F should be capable of being modified into a standard rotary drilling rig.

The debut of XCMG's XR138F low headroom rotary drilling rig encountered an "urgent task". The project needed to ensure the stability and reliability of the underground pipe gallery through support piles. The entire project added 300 support piles, with a drilling depth of 18.5 meters and a drilling diameter of 800mm. To leave sufficient construction time for the subsequent construction, the time for pile foundation construction was rather tight. The XR138F needs to be highly efficient while remaining on the construction site 24 hours a day.

The newly upgraded XCMG XR138F rotary drilling rig is suitable for industrial and civil construction, municipal works, power grid power piles and other fields. It has higher construction efficiency in soil layers, sand layers and other geological conditions. The whole machine is transported with a pole, making it more flexible to move to different sites. More importantly, after the completion of this project, the XR138F can be modified into a standard state within three hours. The multi-functionality of one machine greatly reduces the user's cost input.

As the first battle of the F series, the XCMG XR138F under standard conditions has more powerful performance. It has a maximum drilling depth of 46 meters, a drilling diameter of 1.5 meters, a maximum speed of 45rpm for the power head, and adopts a high-torque reducer and 28mm steel wire rope. The maximum lifting force is 16 tons. It has strong construction capacity and its safety and reliability are far higher than those of its peers.

While ensuring powerful performance, it is also equipped with a National IV Cummins turbocharged engine, which reduces fuel consumption by 5% compared to engines of the same class. The customer highly praised this: "It not only enhances the power but also reduces fuel consumption. It's definitely a huge hit!" "

XCMG's small and medium-sized rotary drilling RIGS are known as the "little steel cannons" in industrial and civil construction. The newly upgraded F series is attributed to XCMG's strong independent innovation capabilities and profound technical research and development capabilities. XCMG rotary drilling RIGS will continue to focus on customer needs, create quality products with craftsmanship, and cultivate the future with integrity.
