Improve efficiency XCMG XR280D II Rotary Drilling Rig

Power system advantages

Equipped with Cummins QSM11 turbocharged engine, with a rated power of 298kW and sufficient power reserve, it is suitable for high-altitude and cold construction sites, and can withstand heavy loads without losing speed when entering rocks.
Advanced electro-hydraulic collaborative control system with adjustable power in multiple gears; Soil saving mode and strong rock penetration mode can be freely switched, with controllable fuel consumption.
Emissions meet standards, noise is low, and the entire machine complies with CE safety standards. Construction sites both domestically and internationally are compliant.

Chassis and overall stability

Hydraulic telescopic widened track chassis, track width 3500-4800mm; equipped with large diameter slewing support, heavy load deep hole and deviated hole drilling machine body is not easy to shake.
The overall weight distribution of the machine is reasonable, and the mast supports ± 15 °/5 ° forward and backward, ± 4 ° left and right tilt angle adjustment, suitable for slope, shore, and restricted site pile foundation operations.
After shrinking the track, the body is compact, easy to disassemble and assemble, and convenient for transfer and transportation.

Durable structure of winch and wire rope

Rear mounted single row rope main winch structure, smooth arrangement of steel wire rope, significantly reduced wear, extended service life of steel wire rope, and lower cost of daily consumables; The maximum lifting force of the main winch is 260kN, with a maximum lifting speed of 60m/min, and high efficiency in lifting and unloading soil.

Strong drilling capability and wide applicability to geological formations

Extreme drilling: maximum drilling depth of 88m, maximum aperture of 2.2-2.5m, standard with multiple specifications of expandable drill rods, and can be extended to adapt to ultra deep pile foundations.
The power head has abundant torque (280kN · m) and supports optional rock reinforcement kit; It can cope with clay, pebble layers, strongly weathered and slightly weathered granite hard rocks, and is versatile for bridges, high-speed railways, building construction, and wind power piles.
Optional supporting pipe drive device and stable oil cylinder, suitable for construction in flowing sand and water bearing strata that are prone to collapse holes.
