XCMG GR3005TIV Mining Motor Grader
Mining operations demand equipment that can withstand relentless punishment while maintaining precise grading capability. The XCMG GR3005TIV answers this challenge with a frame and powertrain engineered for extreme duty cycles. Its 300-horsepower turbocharged diesel engine delivers abundant torque at low RPM, allowing the grader to push through compacted overburden and broken rock without stalling or losing momentum, even on steep mine ramps.
The GR3005TIV features a wider, thicker moldboard blade that provides deeper cutting and wider spreading capability, reducing the number of passes needed to maintain haul roads. Heavy-duty circle drive components are shrouded and sealed against abrasive fines, which significantly extends service intervals compared to standard graders. This attention to mining-specific durability pervades every component of the machine.
Operator protection is central to the GR3005TIV design. The cab is ROPS/FOPS certified to withstand rollover and falling object impacts common in mining environments. An overpressure filtration system prevents dust ingress, maintaining clean air inside the cabin. The isolated cab mounts and sound-dampening materials reduce vibration and noise, helping operators stay alert and productive during extended shifts in remote mine locations.

The GR3005TIV dominates primary and secondary haul road maintenance in large open-pit copper, gold, coal, and iron ore mines. Its wide blade and high downforce capacity enable operators to quickly repair potholes, corrugations, and rutting caused by heavy dump trucks. Consistent road maintenance not only improves truck cycle times but also significantly reduces tire and suspension wear across the entire mining haul fleet.
Bench slope preparation and drain construction are core applications where precision is critical. The GR3005TIV can cut inter-ramp slopes with exactly the specified gradient, ensuring stability and water runoff containment. Its articulated frame provides the tight turning radius needed on narrow benches, allowing miners to get maximum work done from minimal maneuvering space without compromising safety.
Underground mine development also benefits from the GR3005TIV when deployed in larger decline and drift operations. The machine can be configured with a front dozer blade to clear spillage and broken rock before grading, effectively serving as a combined bulldozer and grader. This versatility reduces the number of support machines required underground, where space and ventilation are always at a premium.
Mine rehabilitation projects use this grader for large-scale re-contouring of waste dumps and overburden stockpiles. The GR3005TIV’s substantial weight and traction allow it to push and shape large volumes of unconsolidated material, accelerating the process of returning mined land to a stable, erosion-resistant profile that meets environmental compliance requirements.
Fuel efficiency gains are achieved through an engine management system that automatically matches fuel injection to load demand. When the grader is returning across the pit or idling during shift changes, fuel consumption drops to a minimum. This intelligent control can reduce overall fuel burn by five to eight percent compared to older sequential fuel injection systems, delivering real savings across a multi-thousand-hour mine operating year.
Service and maintenance intervals have been extended through the use of high-capacity filters and improved lubricant reservoirs. The engine oil change interval can reach 500 hours depending on operating conditions, and the hydraulic oil features a kidney loop filtration system that continuously cleans the oil during operation. These extended intervals mean the GR3005TIV spends more time on the haul road and less time in the workshop.
Component commonality with other XCMG mining models simplifies parts inventory management for large mine sites. Many wear parts, filters, and seals are shared across the XCMG motor grader range, allowing mine maintenance planners to stock fewer distinct part numbers. This standardization reduces inventory carrying costs and ensures critical spares are always on hand when scheduled rebuilds or unplanned repairs occur.
The structural durability of the GR3005TIV is the result of extensive finite element analysis and field testing in active mine sites. Frame stress risers have been eliminated through smooth transitions and interlocking plate designs. The rear frame section includes integrated lifting lugs rated for the full operating weight, enabling safe and rapid hoisting during major component exchange procedures conducted in the mine maintenance bay.
Corrosion and abrasion protection measures are comprehensive. The blade moldboard surface is hardfaced with a chromium carbide overlay in high-wear zones near the cutting edge attachment area. The exterior paint system includes an epoxy primer and polyurethane topcoat designed to resist the corrosive effects of acidic mine water. Enclosed compartments such as the articulation joint area are coated with cavity preservation wax for long-term protection.
Remote monitoring capability is available as an optional upgrade, allowing mine fleet managers to track machine location, engine hours, fault codes, and maintenance alerts from a central control room. This telematics system helps optimize machine deployment, anticipate maintenance needs, and maintain a complete digital service history for every asset. Proactive maintenance based on real-time data prevents minor issues from escalating into major unscheduled stoppages.
Selecting the GR3005TIV for your mining fleet means equipping your operation with a grader that has been designed, built, and tested specifically for the unique demands of mineral extraction environments. It is not a lightly modified construction grader, but a dedicated mining tool that brings higher productivity, improved safety, and lower long-term ownership costs to the toughest job sites on the planet.
With XCMG’s growing global support network, mine operators benefit from rapid parts availability, technical training, and on-site service assistance. This ensures that the GR3005TIV remains a reliable production asset throughout its operating life, contributing to mine profitability year after year. Invest in a motor grader that matches the intensity of your operation and experience the difference that purpose-built engineering makes.
