High loop efficiency XCMG XR400E Rotary Drilling Rig

Power and drilling performance advantages

High torque power head, strong adaptability to geological formations
The rated torque of the power head is 400kN · m, supporting three modes of switching: ordinary soil mode, rock entry mode, and energy-saving mode; Strong penetration ability against sand layers, pebbles, and moderately weathered rock layers, stable footage in soft and hard formations, and reduced tool wear.
High power electronic control engine with sufficient power reserve
Equipped with Cummins electronic fuel injection engine, with three adjustable power levels. Low grade and fuel-efficient use of soft soil layers, full power opening for hard rocks and deep holes; The power attenuation is small under high-altitude working conditions, and the reliability of continuous heavy load operation is high.
Dual pressure scheme optional
Standard pressurized oil cylinder, optional winch pressurization; Deep and large hole drilling with sufficient pressure effectively prevents slippage and improves rock entry efficiency.

Structural design highlights

XCMG single row rope main winch
Industry classic design, single row arrangement of steel wire rope throughout the entire process, eliminating multi-layer winding, biting, and grinding of the rope. The service life of the steel wire rope is greatly improved, reducing the long-term cost of consumables.
H-type telescopic track chassis+heavy-duty slewing bearing
The track is extendable, with a wide construction deployment width and strong anti overturning ability of the whole machine; Deep hole and large aperture construction is less prone to shaking, and the verticality of the hole is better; After contraction, it is convenient for the entire vehicle to be towed and transferred.
Optimize the double arm/large triangle amplitude mechanism
The drilling mast has strong rigidity and excellent bending resistance; The large depth drilling mast has minimal deformation, ensuring the verticality of the pile hole; Balancing construction stability with ease of disassembly and transportation.
Efficient heat dissipation hydraulic system
Load sensing hydraulic+three in one combination radiator, making continuous high-temperature construction less likely to cause overheating and vehicle blockage; Reasonable matching of hydraulic power, reduced energy loss under no-load, and better overall fuel consumption.
