A Cornerstone of the Industry: What Is a grader
In order to understand the road construction industry in depth, we must first make clear what a grader is. It is characterized by having a long adjustable blade.For those enterprises involved in the export of construction machinery, graders play an important role in several key stages of road construction. It carries out ground leveling to create a flat foundation for subsequent road construction projects; It smooths and grades the sub-base, uniformly spreading layers of soil and gravel; In addition, it can also repair slopes and sloping road to achieve the goal of drainage.
According to the latest report by market research firm IMARC Group, the global motor grader market demonstrated robust growth in 2024, reaching a market size of approximately US$7.2 billion. This figure reflects the sustained demand for motor graders—core equipment in infrastructure development—across sectors such as road construction, land leveling, and mining operations.

Case Study
- The Challenge: A mountainous highway project was plagued by delays. Existing grader lacks the power and accuracy of a steep slope of 28, and can only achieve the accuracy of 8 mm /3 m, which led to repeated rework and high fuel consumption (33 L/h).
- The Solution: Deployment of the XCMG GR2605T.
- The Result: The accuracy was immediately improved to 3 mm /3 m, and rework was avoided. Fuel consumption dropped to 28 liters per hour. The project not only resumed its progress, but also finished 12 days ahead of the revised target, saving about 60,000+annually US dollars in operating costs every year. This situation has consolidated its reputation as the primary road construction machinery in challenging terrains.

Frequently Asked Questions
Q 1: During operation, the blade move slowly and the pressure of the hydraulic system is insufficient. How to diagnose?
A: ① Check the pressure of the main safety valve (standard: 28 MPa) If insufficient, adjust to the standard value; If the spool is stuck, flush it using a specialized cleaning agent); ② disassemble the hydraulic pump and check the wear of the plunger (if wear exceeds 0.1 mm, it needs to be replaced); ③ test the contamination level of the hydraulic oil (if exceeding NAS Class 8, replace the oil; L-HM 46 anti-wear hydraulic oil is recommended).
Q 2: In high-dust environments, engine power drops and fuel consumption increases. What is the possible reason?
A: ① Disassemble the air cleaner assembly, remove the dust from the primary filter, and replace the filter element of the secondary filter (change it regularly every 800 hours); ② Inspect the turbocharger intake duct for dust accumulation and purge it using compressed air; ③ check whether the fuel filter elements is blocked (if the three-stage filtration system is used, please replace all elements at the same time).
Q 3: After starting the engine at low temperature, the braking system fails and the machine cann’t move normally. How to solve this?
A: ① Activate the braking system preheating function (wait 10 minutes) to ensure the brake fluid temperature rises above 10 ° c; ② check the viscosity of the brake fluid (if it has solidified, replace low temperature DOT 4 brake fluid); ③ check whether there is air entering the brake pipeline, and use the air release valve to discharge the air.
Q 4: During leveling operations, the accuracy is not up to standard, and the road surface shows wave-like fluctuation. What are the underlying problems?
A: ① Calibrate the blade level sensor (the allowable error must be less than 0.1); ② adjust the running speed (2-4 km/h recommended; Avoid speed too fast, which can lead to insufficient leveling); ③ check the clearance of the slewing bearing (if the clearance exceeds 0.5 mm, adjust or replace the bearing).
Q 5: After purchasing the GR2605T, how should I choose the appropriate working accessories? What are the applicable application scenarios for the different accessories?
A: ① Standard blade (3965 × 610 mm): it is suitable for subgrade construction and site leveling; ② ripper (3-shank): Suitable for breaking up hard soil and weathered rock; ③ snow plough (4.2 m): (width): It is suitable for large-scale snow removal in winter.
