The GR3003 is the flagship model of XG's G series motor graders, positioned as a "powerful tool for mines and major projects". Its core objective is to offer unparalleled operational efficiency, ultimate reliability and an intelligent operation experience, meeting the highest demands of global high-end users for productivity and return on investment.
The friction-disc worm gearbox with overload protection is developed for the mining heavy load condition, which can slip automatically and protect the safety of the machine and personal. Load sensing hydraulic system is equipped with variable piston pump and load sensing multi-way valve, in order to improve operation comfort, the pilot independent electrical proportional valve, the main directional valve and relief valve are proportional valves. Spacious cabin design, three-dimensional air duct, good driving experience. Double handle operation can be selected on the handle operation, reducing the labor intensity by about 80%.

Large-scale open-pit mines: tunnel construction, leveling of mining and excavation platforms, and operations at waste dumps.
The base leveling of large-scale engineering projects: large DAMS, nuclear power plants, port terminals and other infrastructure.
High-grade highways: Final leveling and super-large engineering volume shaping of expressway subgrades.
Others: Any situation where there are extreme requirements for equipment power, durability and operational efficiency.
Before starting the work, be sure to conduct a self-check of the equipment through the intelligent display screen. After starting, use the electronic control system to idle for preheating. Its intelligent electro-hydraulic handle is integrated for control, ensuring precise and effortless operation. When performing heavy-duty cutting, it is recommended to select the "heavy-duty" power mode. It is strongly recommended to use the integrated 3D automatic leveling system to achieve ultra-high precision operations. Extra caution should be exercised on slopes and in complex working conditions. Be sure to give way. Before parking, make sure the scraper touches the ground smoothly and turn off the engine. Strictly abide by all safety regulations to ensure the safety of both personnel and machines.
FAQ
A: Its core advantages are reflected in
Ultimate reliability: Specially designed for heavy-load impact conditions in mines, all structural components and parts are top-notch configurations, offering unparalleled durability.
Intelligent and efficient: The intelligent electronic control system achieves the best match between power and hydraulics, with fast response and high efficiency, and is natively integrated with a 3D intelligent leveling system.
Top-notch comfort: The six-point suspended silicone oil shock-absorbing cab offers the industry's top operational comfort and safety.
A: Although the technology is advanced, the maintenance is not complicated. It adopts a modular design, making fault diagnosis simpler. Maintenance reminders and fault codes can be obtained in real time through the intelligent display screen in the driver's cabin, guiding maintenance personnel to quickly locate problems. The daily maintenance points are also centrally arranged for convenient operation.
A: The cab is spacious, well-sealed, equipped with air conditioning and shock-absorbing seats. The operation handle is ergonomically designed with a wide field of vision, which can effectively reduce the fatigue caused by long-term driving.
A: The design is very easy to maintain. The engine hood can be opened at a large Angle for convenient maintenance. The most important thing is that it is equipped with a centralized lubrication system as standard. Just add grease at one point, and it can quickly complete the lubrication of multiple important hinge points, saving time and effort and effectively extending the service life of the equipment.
A: Work should be stopped immediately. Refer to the manual to confirm the meaning of the alarm. Common ones include engine oil pressure alarm, excessively high water temperature alarm, etc. If it cannot be solved by yourself, you should immediately turn off the engine and contact the after-sales service personnel.
A: There could be many reasons, for example:
Engine fuel system issues (such as clogged filters, etc.).
Hydraulic system issues (insufficient hydraulic oil, clogged filter element, internal leakage in the system).
Improper operation (setting the gear too high).
It is recommended to start with simple checks (such as oil and filter elements). If the problem persists, it should be repaired by a professional technician.
