Key Features and Applications
High-Power Mining Powertrain
The GR5505 is equipped with a high-horsepower industrial diesel engine providing 447 kW of output. Combined with a heavy-duty AMT (Automated Manual Transmission) gearbox featuring lockup capabilities and an advanced wet brake rear-axle, the powertrain delivers immense torque and reliable traction for continuous mining operations.
Heavy-Duty Structural Design
Built for the harsh conditions of open-pit mining, the grader features high-strength structural parts. The massive 7,300 mm wide blade is engineered for high durability, allowing it to efficiently level compacted earth, frozen soil, and heavy aggregates without deformation.
Intelligent and Ergonomic Cabin
The operator environment features a ROPS & FOPS certified cabin. It includes a pressurized, self-cleaning system to prevent dust ingress, an adjustable suspension seat, and an electric control double-handle setup. These features significantly reduce operator fatigue and enhance visibility and safety during long shifts.
Optimized Cooling and Environment Adaptability
Designed for severe environmental conditions, the cooling system features a scientifically optimized layout that creates a “chimney effect” in the air duct design, reducing hot air vortexes. This ensures the engine and hydraulic systems maintain stable operating temperatures even in extreme climates, including ultra-low temperature environments.
Versatile Mining and Infrastructure Utility
The GR5505 is a multi-purpose machine ideal for:
-
Open-Pit Mining: Heavy load bulldozing, haul road maintenance, and landform finishing.
-
Large-Scale Earthmoving: Ground leveling, slope scraping, and trenching.
-
Extreme Conditions: Large-area snow removal and frozen soil preparation.

Dimensions and Operating Range
The XCMG GR5505 is a giant-class grader with massive dimensions to match its heavy-duty applications. The vehicle operates with a large 7,300 mm wide blade that allows for wide-pass grading, significantly reducing the number of passes required to maintain wide mine haul roads. Despite its size, the articulated frame allows for a minimum turning radius of 12.5 meters, providing necessary maneuverability within open-pit confines and large construction sites.
