Technical Specifications to Verify

When evaluating technical specifications, the hydraulic system’s performance is paramount, with observed working pressures ranging from 16MPa to 24MPa. Higher pressure systems generally offer greater force for blade engagement and lift capabilities, which is essential for heavy cutting or moving dense materials. Buyers must verify the rated power and speed parameters, such as 100/2200kw/Rpm or 75(2400r/Min), to ensure the engine output matches the hydraulic demands of the front discharge mechanism. The frame articulation angle and maximum lift above ground, noted at 410mm in some listings, directly impact the machine’s maneuverability and the height to which material can be discharged, influencing efficiency in road building and drainage projects.

Tire specifications and ground clearance are critical for stability, especially when the grader is operating on uneven terrain or carrying a front load. The tread width of 1900mm and space between front and rear axles of 4885mm contribute to the machine’s overall stability and turning radius. Buyers should also check the blade cutting angle, which ranges from 28 to 70 degrees in some models, as this determines the versatility of the grader for different grading tasks. Verifying the total weight, such as the 700kg for smaller units or 16722kg for larger graders, is essential for calculating transport costs and ensuring the machine’s weight is appropriate for the soil bearing capacity of the work site.

Compliance and Safety Documentation

Certification requirements vary by destination market, with CE, RoHS, ISO, TUV, and UL marks appearing across different listings. Buyers must confirm that the specific model they intend to purchase holds the certifications required for import and operation in their target region. For instance, European markets typically mandate CE marking, while other regions may have specific safety standards that align with ISO or TUV certifications. It is crucial to request copies of these certificates from the supplier before finalizing the purchase, as the presence of a certification on a general product page does not guarantee that every individual unit shipped will meet those specific regulatory requirements for the buyer’s jurisdiction.

Safety documentation should include detailed operator manuals, maintenance schedules, and safety warnings specific to the front discharge operation. Buyers should verify that the machine includes necessary safety features, such as emergency stop mechanisms and protective guards for hydraulic lines. The condition of used equipment, such as the STG210C, requires additional scrutiny of its maintenance history to ensure that safety systems have been properly serviced. Ensuring that all documentation is provided in a language understandable by the local operators is also a key compliance step, facilitating proper training and reducing the risk of accidents due to misinterpretation of safety protocols.

Cost Drivers and Commercial Terms

The price range of $1 to $447,000 USD highlights the significant impact of machine size, engine brand, and condition on total cost. Larger graders with higher horsepower and heavier weights naturally command higher prices due to the increased material and manufacturing costs involved. Buyers should also consider the cost of customization, as available options for specific configurations may add to the base price. Additionally, the choice between new and used equipment involves a trade-off between upfront cost and long-term reliability, with used units offering lower initial investment but potentially higher maintenance expenses over time.

Commercial terms such as packing and shipping methods also influence the total landed cost. Nude packaging is common, which reduces packaging costs but may increase the risk of damage during transit, potentially leading to additional insurance or repair costs. Buyers should negotiate clear terms regarding delivery, including lead times and responsibility for loading and unloading. Understanding the container capacity, such as the 1unit/40' HQ Container specification for the HY120G, helps in planning logistics and optimizing freight costs. Clear communication regarding payment terms and warranty coverage is essential to mitigate financial risks associated with international procurement.

Supplier Qualification and Quality Control

Supplier qualification is critical when sourcing heavy machinery, as the quality of manufacturing directly impacts machine longevity and performance.
