FAQ
Q: How much more expensive is a 4-axle dump truck compared to a 3-axle one? Is it a worthwhile investment?
A: With identical specifications, it costs an additional 10,000–20,000 RMB. However, since it can haul an extra 5–10 tons per trip, given a stable source of cargo, you can recoup the price difference within six months to a year. In the long run, it proves to be a more cost-effective choice.
Q: Is a liftable axle necessary?
A: It is highly practical. When the vehicle is unloaded or lightly loaded, lifting the first axle helps save fuel, reduces tire wear, improves steering agility, and results in slightly lower toll fees.
Q: How should I choose between a U-shaped dump body and a square-shaped one?
A:U-shaped body: Offers clean unloading with no material residue, features a lighter curb weight and larger volume, and is ideal for transporting sand, gravel, coal, or ore (currently the mainstream choice).
Square-shaped body: Possesses a more rigid structure and is suitable for hauling blocky or angular materials; while slightly more versatile, it is prone to material residue accumulation.
Q: How should I maintain the hydraulic system?
A: Replace the hydraulic oil after the first 50 hours of operation. Subsequently, replace the oil and filter element every 3–6 months or every 500 hours. Ensure the oil remains clean and free of impurities. When lifting the dump body, avoid uneven loading, do not exceed the maximum stroke limit, and never perform lifting operations while parked on a slope.
Q: Can a 4-axle dump truck be used to transport excavators or heavy equipment?
A: It is not recommended. The dump body sits high, the vehicle lacks loading ramps, the center of gravity is elevated, and it is prone to exceeding legal height/weight limits. For transporting construction machinery, using a gooseneck lowboy trailer is a safer and more compliant option.
