The XCMG XR150D Rotary Drilling Rig is a versatile and efficient machine designed for foundation construction projects such as urban development, railways, highways, bridges, subways, and buildings. It features a dedicated hydraulic retractable crawler chassis and a large-diameter slewing bearing, providing exceptional stability and ease of transport. Powered by a Cummins electric control turbocharged engine, the XR150D delivers robust performance while meeting Euro III emission standards. The hydraulic system employs threshold power control and negative flow control, enhancing efficiency and energy conservation. A single-rope winding mechanism effectively reduces steel wire rope wear, extending its lifespan. The rig's design complies with CE directives, ensuring safety during operation. Optional centralized lubrication systems facilitate maintenance, and various drill rod configurations are available to suit different geological conditions. The XR150D is capable of achieving a maximum drilling diameter of 1,500 mm and a maximum drilling depth of 55 meters, making it suitable for a wide range of construction applications
