The GR5505T is designed to withstand the harshest mining environments. Every structural component is made of high-strength steel and undergoes advanced heat treatment. The main frame features a welded, reinforced section, which reduces fatigue even on rocky terrain. The chassis geometry ensures optimal weight distribution and exceptional traction on steep slopes.
The optional four-wheel-drive system with limited-slip differentials allows the GR5505T to maneuver with precision on loose or muddy surfaces. The drive axles feature a modular design and utilize planetary final drives that multiply the available torque. The 17.5-25 mining tires provide a wide footprint to minimize soil compaction.
The GR5505T’s diesel engine meets Tier 3 / Stage IIIA emissions standards, combining high-pressure electronic fuel injection with a variable-geometry turbocharger. The flat torque curve ensures immediate responsiveness without the need to constantly downshift. The high-capacity cooling system maintains optimal temperatures during extended shifts, reducing thermal stress.
ECO mode automatically adjusts power delivery based on the implement’s demand, achieving fuel savings of up to 12% compared to previous models. The 450-liter fuel tank allows for full workdays without refueling, increasing net productivity in remote operations.
The GR5505T features a load-sensing variable-displacement piston pump. This technology delivers exactly the flow required for each function, reducing heat generation and energy consumption. The electro-hydraulic controls provide a smooth, proportional response, ideal for finishing work on slopes or ditches.
The dozer blade circuit allows for a 360-degree rotation range, a side tilt of up to 90 degrees, and hydraulic side shift. It can be optionally equipped with a front blade for pushing material or a 5-tine rear ripper for breaking up compacted layers.
The GR5505T operator station is ROPS/FOPS certified and features an ergonomically designed layout. Air-suspension seats and adjustable armrests reduce fatigue during 12-hour shifts. Panoramic visibility is optimized by tinted laminated glass and a low-profile hood. The high-capacity HVAC system keeps the cab pressurized to prevent dust from entering.
The digital color instrument panel displays real-time data on engine performance, fuel consumption, pressure readings, and diagnostic alerts. The GR5505T can be equipped with the XCMG X-Connect telematics system, which allows users to monitor location, operating hours, and scheduled maintenance via a web platform. An optional rearview camera enhances safety during reverse maneuvers.
The multifunction joystick combines controls for the blade, travel, and auxiliary functions. The dual-cylinder hydraulic steering system provides precise steering with minimal effort. The GR5505T can also be equipped with the XCMG Grade Assist automatic leveling system, which uses rotation sensors and inclinometers to maintain the desired slope without constant manual intervention.
Daily maintenance points are grouped at ground level, including dipsticks, filters, and centralized lubrication points. Engine oil change intervals are extended to 500 hours thanks to high-efficiency filters and a sealed crankcase ventilation system. The modular radiators can be easily cleaned via a hinged access panel.
The bushings and pins on the blade and ring are sealed and lubricated for life in most joints. The GR5505T features a hinged rear frame design that protects the drivetrain from severe impacts. The availability of XCMG spare parts is supported by distribution centers throughout the region, reducing downtime.
The GR5505T is the top choice for maintaining haul roads in copper, coal, and iron mines. It is also used in the construction of drilling platforms, the grading of spoil piles, slope profiling, and the cleaning of drainage ditches. Its wide range of speeds makes it versatile for both precision work and travel between job sites.
XCMG has incorporated technologies into the GR5505T designed to reduce its environmental footprint. The engine meets strict emission standards, and the low-noise cooling system minimizes noise pollution in the surrounding area. More than 90% of the materials used in its manufacture are recyclable at the end of its service life.
In addition, the automatic idle mode shuts off the engine after a configurable period of inactivity, saving fuel and reducing CO₂ emissions. Intelligent hydraulic fan control adjusts the fan speed based on actual cooling demand, contributing to optimal energy efficiency.
The XCMG GR5505T isn’t just a motor grader—it’s a comprehensive solution for modern mining. Contact us to find out how it can transform your operation’s productivity.
