The chassis of the GR3505T motor grader is constructed from high-strength steel that has undergone advanced heat treatment. This process ensures optimal shock absorption and superior torsional strength, even when the machine is operating on rocky terrain with severe irregularities and steep slopes.
The pivot points have been reinforced with large-diameter bronze bushings and hardened pins, which minimizes wear at critical joints and significantly extends maintenance intervals. The balanced weight distribution ensures consistent traction on all wheels.
The front frame system allows for a wide turning angle, facilitating precise maneuvers in confined spaces—an essential feature at mine faces where workspace is limited and every movement must be executed with the utmost precision.
At the heart of the GR3505T is a turbocharged inline-six diesel engine with high-pressure electronic fuel injection. This engine delivers a rated power output of 261 kW, equivalent to 350 horsepower, with maximum torque available from low RPMs to handle the most demanding tasks without any loss of performance.
The engine’s electronic management system optimizes fuel consumption in real time, automatically adapting to load conditions. In mining operations where every liter of diesel directly impacts profitability, this efficiency translates into substantial savings over the equipment’s service life.
The cooling system is designed to withstand extreme climates, featuring a high-flow radiator and a viscous coupling fan that adjusts its speed based on temperature. This feature allows the machine to operate without overheating in mining deserts or at altitudes above 4,000 meters above sea level.
The GR3505T features a closed-center hydraulic system with load sensing technology, which delivers fluid flow only when functions require it. This design reduces energy consumption and heat generation, extending the life of the hydraulic oil and all circuit components.
The 4.27-meter-long dozer blade can tilt, rotate, and traverse sideways with exceptional smoothness thanks to double-acting hydraulic cylinders. The operator controls each movement using ergonomic joysticks with proportional response, achieving a precision finish when grading mine platforms and roads.
The optional rear ripper system adds versatility, allowing for the scarification of compacted surfaces prior to grading. The GR3505T can be configured with a variety of attachments that expand its range of applications beyond traditional mining into road construction and the maintenance of large industrial sites.
The ROPS/FOPS cab on the GR3505T has been designed with the operator in mind. The large windows provide panoramic visibility of the work area, eliminating blind spots that could compromise safety. The laminated windshield and tempered side windows offer protection against impacts and flying debris.
The pneumatically adjustable seat absorbs ground vibrations, reducing fatigue during long shifts. The automatic climate control system maintains a constant interior temperature regardless of external conditions, a crucial factor when operating in mining regions with extreme temperature fluctuations between day and night.
The digital instrument panel provides real-time information on the machine’s status, including fuel consumption, fluid temperatures, and predictive maintenance alerts. The intuitive interface minimizes the learning curve for new operators and makes it easy to monitor critical operating parameters.
Safety is a cornerstone of this mining motor grader’s design. The oil-immersed multi-disc braking system ensures reliable stopping power even on steep slopes when fully loaded. The automatic parking brake engages when insufficient hydraulic pressure is detected, preventing the machine from rolling away during stops.
High-intensity LED work lights fully illuminate the work area during night shifts. Non-slip steps and strategically placed handrails facilitate safe access to the cab and maintenance points, complying with international safety standards for heavy machinery in mining environments.
The audible and visual backup alarm system alerts all personnel in the vicinity when the machine is moving in reverse. Additionally, the GR3505T can be equipped with proximity detection systems and rearview cameras that enhance safety during operations involving a high density of personnel and auxiliary equipment.
XCMG has prioritized serviceability in the GR3505T. The engine covers open fully, providing direct access to daily inspection points without the need for special tools. The oil, fuel, and air filters are grouped in a centralized compartment, which reduces the time required for routine preventive maintenance.
The lubrication points are marked with colored indicators and are mostly accessible from ground level. This design feature reduces the risks associated with working at heights and speeds up lubrication tasks, allowing the equipment to return to production as quickly as possible after each scheduled shutdown.
The onboard diagnostic system continuously monitors the machine’s vital parameters and alerts the operator to anomalies before they develop into major failures. This predictive maintenance capability reduces unplanned downtime and optimizes the operational availability of the mining fleet—a critical factor where every hour of downtime results in significant financial losses.
The GR3505T proves its worth in the world’s most demanding mining operations. From maintaining haulage ramps in copper mines in South America to grading drill pads in iron ore mines in Australia, this motor grader adapts to a variety of geological and climatic conditions without compromising its productivity or structural reliability.
The GR3505T also plays a key role in large-scale civil infrastructure projects. The construction of highways, airports, and earthen dams benefits from its ability to move and spread material with precision, creating perfectly level surfaces that meet the strictest tolerances specified in engineering specifications.
The robustness of the powertrain and the quality of the materials used in its construction ensure that the GR3505T retains a high residual value even after years of intensive use. Mining companies and contractors view this model as a sound investment, backed by XCMG’s growing global presence and its spare parts distribution network in major international mining markets.
The combination of robust engineering, fuel efficiency, and low operating costs positions the GR3505T as one of the most competitive options in the market for high-capacity mining motor graders. The availability of spare parts at major mining logistics hubs ensures responsive after-sales support that minimizes unscheduled downtime during peak production seasons.
The modular design of its main components allows for major repairs to be carried out without having to dismantle adjacent systems, a significant advantage when maintenance must be performed in the field. Extended oil change intervals and the durability of the undercarriages underscore XCMG’s commitment to excellence in heavy engineering for the global mining industry.
Every GR3505T motor grader that rolls off the production line embodies decades of experience XCMG has accumulated in manufacturing machinery for mining, construction, and infrastructure.
