The XCMG D260 coal type bulldozer is a specialized heavy-duty crawler tractor meticulously engineered for high-production coal mining and bulk material handling. Built on decades of XCMG innovation, the D260 integrates a powerful, fuel-efficient engine with a rugged undercarriage to sustain relentless pushing force in abrasive coal seams. Its reinforced blade, advanced cooling system, and intelligent control make it the ideal partner for stripping overburden, stockpile management, and bench preparation. Whether operating in deep pits or high-altitude mines, the D260 delivers lower cost per ton, exceptional uptime, and operator confidence.
XCMG D260 Coal Type Bulldozer
At the heart of the XCMG D260 coal bulldozer lies a high-torque, electronically controlled diesel engine that meets stringent emission standards while delivering consistent power at low rpm. The hydro-mechanical powertrain seamlessly adjusts speed and drawbar pull to match load variations, ensuring efficient fuel utilization even during peak push cycles.
The engine’s multi-stage filtration and advanced thermal management guarantee reliable operation in dusty, high-temperature mining environments. An automatic engine idle and shutdown system further reduces fuel consumption during waiting periods, lowering overall operating costs.
With a net output exceeding 220 kW, the D260 can handle massive coal and overburden volumes. The torque converter multiplies breakout force when engaging the pile, while the lock-up clutch provides direct drive for high-speed reverse and dozing, improving cycle times dramatically.
The D260 features a fully redesigned mainframe and pivot shaft engineered to absorb shock loads typical in coal seam ripping. Heavy-duty steel castings are used in critical stress areas, and the equalizer bar is enlarged to distribute impact forces evenly across the track frame.
Its semi-U coal blade is fabricated from high-abrasion-resistant steel with a reinforced center section and replaceable cutting edges. The blade capacity of over 6.8 cubic meters allows the D260 to move more material per pass, while the optimized curvature reduces rolling resistance in loose coal.
A robust C-frame and angled push arms provide excellent blade penetration and stability. Special dust seals on all hinge points prevent abrasive coal particles from entering, significantly extending pin and bushing life.
The elevated sprocket undercarriage of the XCMG D260 keeps the final drive out of the abrasive coal fines, drastically reducing wear. Heavy-duty track chains with sealed and lubricated links are designed for extended service intervals and smooth articulation over uneven pit floors.
Carrier rollers and track rollers are equipped with double-cone seals and lifetime lubrication, isolating internal components from moisture and grit. The triangular track frame geometry provides a large ground contact area, delivering low ground pressure and superior flotation on soft coal pads.
Oversized idlers and a suspended undercarriage absorb terrain irregularities, protecting the machine structure and improving operator comfort. The standard track shoe width is optimized for coal, but alternative configurations are available upon request.
Recognizing the extreme dust generated in coal handling, the D260 employs a high-efficiency, wide-core radiator with a hydraulically driven variable-speed fan. The fan automatically reverses at preset intervals to expel debris from the cooling pack, maintaining optimal engine temperature without operator intervention.
A multi-cyclone pre-cleaner ejects up to 90% of incoming dust before it reaches the air filters, preserving engine life. The engine enclosure is pressurized to prevent dust ingress, and strategic air inlets draw cooler, cleaner air from above the machine.
These features drastically reduce radiator clogging and downtime caused by overheating, allowing the D260 to sustain peak power in the harshest coal mine environments, shift after shift.
The XCMG D260 cab is ROPS/FOPS certified and isolated from the chassis by viscous mounts to reduce whole-body vibration. A pressurized cabin with automatic climate control keeps the interior clean and comfortable, enhancing operator alertness during long shifts.
An ergonomic joystick with integrated proportional controls provides fingertip command of blade tilt, angle, and ripper functions. The intuitive layout of the 7-inch color monitor displays engine parameters, fuel consumption, and machine diagnostics at a glance.
A heated air-suspension seat with adjustable armrests accommodates operators of all sizes, and the low-effort steering system minimizes fatigue. Sound levels inside the cab remain well below international standards, allowing clear communication and concentration.
Daily service points on the D260 are grouped at ground level and accessible through wide-opening doors. The hydraulic oil reservoir features a sight gauge, while centralized grease banks reduce manual lubrication time.
An integrated vehicle health monitoring system records operational data and alerts the maintenance team to upcoming component wear. The engine oil change interval is extended through high-capacity filtration, and the modular powertrain design enables rapid component exchange.
The articulated hood lifts effortlessly on gas struts, exposing the entire engine bay. Major components, including the transmission and final drives, can be removed independently without disturbing other systems, cutting typical rebuild time significantly.
Equipped with a high-pressure common rail fuel system and cooled exhaust gas recirculation, the D260 meets regional emission regulations without compromising power. The machine is compatible with biodiesel blends, supporting mine operators’ sustainability goals.
XCMG’s engine management software optimizes fuel mapping for coal pushing cycles, reducing unburned hydrocarbons and particulate matter. The idle shutdown and eco-mode functions further minimize carbon footprint during waiting periods.
The long-life undercarriage components and remanufacturable parts lower the total lifecycle environmental impact. At the end of service, more than 95% of the D260’s materials can be recycled.
Standard safety features include wide-angle rearview cameras, LED work lights providing 360-degree illumination, and a travel alarm. The hydraulic system incorporates check valves on all lifting circuits, preventing unexpected blade drop.
An emergency engine stop is accessible from both the cab and ground level. Optional proximity detection and fire suppression systems are available to meet site-specific requirements, making the D260 one of the safest bulldozers in its class.
