The 215HP Mini Grader (Model GR2153) combines compact design with high performance, featuring an overall length of 7.8m, width of 2.5m, and weight of 16,500kg—making it easy to transport via medium-duty trucks. Powered by a 164kW QSB6.7 engine (with a 500-hour oil change interval), it delivers consistent power for long working shifts. Its 7.3m minimum turning radius allows smooth operation in narrow spaces like rural village roads or urban alleyways, solving the problem of large graders being unable to access confined construction sites.
Energy Efficiency: Low-speed transmission (optimized gear ratio of 1:3.2) reduces fuel consumption by 8% compared to traditional graders of the same horsepower; the engine’s intelligent idle function automatically lowers speed to 800rpm when the machine is idle for over 5 minutes.
High Traction: Herringbone tread tires (16.00-24 size) boost adhesion by 10% on loose soil, and the optional tire chain kit further enhances grip on icy or muddy terrain, reducing slippage rate by 15%.
Rapid Operation: Hydraulic pump displacement optimization (increased from 80mL/r to 95mL/r) increases cylinder speed by 20%, shortening blade lifting and tilting time by 1.2 seconds—improving overall work efficiency by 18% for small-scale road repairs.
Durability: High-frequency quenched blade (surface hardness up to HRC 55) with extended service life; the machine’s frame adopts 16mm thick high-strength steel, and key welds are reinforced with ultrasonic testing to resist deformation during heavy loads.
Widely used in road repair (filling potholes and leveling uneven asphalt surfaces), rural highway construction (connecting villages with county roads), railway subgrade leveling (preparing for track laying), and urban landscaping (grading green belt foundations). It is particularly adaptable to mountainous areas (with slopes up to 20°) and confined spaces like scenic area tourist roads or factory internal roads, where large construction equipment cannot operate.
Q: What certifications does it have?
A: CE (meets EU safety standards), EPA (U.S. environmental protection requirements), and ISO 9001 (quality management system certification), ensuring compliance with global market access requirements.
Q: How to address engine black smoke?
A: First, inspect the fuel injection system (check if injectors are clogged or leaking) and clean the air filter; if the problem persists, check the turbocharger’s rotational speed (should be ≥120,000rpm at full load) to avoid insufficient air intake.
Q: What is the maximum working slope it can handle?
A: The maximum safe working slope is 20°; it is recommended to use the low-speed gear and activate the slope stabilization function when working on slopes exceeding 15° to prevent rollover.
