Recently, at the construction site of Binjiang Road in Jiang'an District, Chongqing, a Beijing CRRC Heavy Industry TR228H rotary drilling rig, after 6 hours of continuous operation, continuously drilled 1.25-meter diameter argillaceous sandstone in the rock layer at a depth of 40 meters, once again demonstrating CRRC rotary drilling rig's strong rock-penetrating capability and being called the “Tough Guy” on the site.


　　According to on-site construction standards, the pile diameter is required to be 1.25 meters, and the pile depth must reach 40 meters, which means the drilling tool must embed into the argillaceous sandstone at 40 meters. Such difficulty made many rotary drilling rig owners on site scratch their heads, but the owner of the Beijing CRRC Heavy Industry TR228H remained calm and composed, directing the machine to drill down and lift. According to calculations, based on the hard rock conditions on site, the Beijing CRRC Heavy Industry TR228H rotary drilling rig is about 30% more efficient than other machines of the same ton-meter class on site, and also has certain advantages in hole quality and core integrity, truly deserving the title of “Tough Guy”.


　　According to service personnel, Beijing CRRC Heavy Industry rotary drilling rigs are widely praised in the industry for being economical, efficient, reliable, and intelligent. Nicknamed “Tough Guy”, the CRRC TR228H rotary drilling rig is designed with a power combination system for different working conditions, featuring high output torque, strong engineering adaptability, high matching degree, and strong rock-penetrating capability, enabling 24-hour construction in various complex geological formations. In particular, with innovative applications in key components such as working devices, hydraulic systems, and control systems, the TR228H rotary drilling rig, compared with products of the same ton-meter class, has characteristics such as wide operating range, high construction efficiency, strong power, stable performance, high reliability, and easy installation, making it a leader among domestic products of the same class.
