High verticality of hole‑forming XCMG XR280D Rotary Drilling Rig

Power and rock penetration ability

The maximum torque is 280kN · m, equipped with Cummins high-power engine, with sufficient power reserve. The power head comes with a dual mode of soil layer/rock penetration, with high drilling efficiency in hard rock, pebble, and granite formations, and can cope with complex geological pile foundation projects. Engine hydraulic system matching optimization, continuous operation under heavy load without losing speed, excellent fuel consumption control.

Chassis and overall stability

Special hydraulic telescopic track chassis+large diameter slewing support, wide construction grounding and strong anti overturning ability; After retracting the tracks, the overall width of the machine narrows, making it easier to transport and transfer. Double box variable amplitude mechanism, strong rigidity of mast, hole verticality ≤ 0.3%, suitable for high standard pile foundation requirements of high-speed railways and bridges.

Advantages in winch structure and consumables cost

The rear single row rope main winch has much less wear on the steel wire rope compared to multi-layer winding, which increases the service life of the steel wire rope by 2-4 times and significantly reduces the cost of consumables. Standard winch pressurization, optional oil cylinder pressurization, casing drive, and long spiral expansion module, versatile for one machine.
