FAQ
Q: Is the engine fuel-efficient but still strong?
Yes. The WP engine gives peak torque at low RPM, so you don't rev hard to get power. Less revving means less fuel. Small axle ratios on the tractor keep highway RPM low, saving real money on long runs.
Q: Will the tipper chassis crack under heavy loads?
No. It has a double-layer high-strength steel frame, reinforced hinge and lift mounts, plus hub-reduction axles with bigger shafts. Built for twisted, rocky ground every day.
Q: Is the AMT gearbox reliable?
Yes. It's the same tough manual gearbox with a smart shift unit added. It shifts like a good driver, cuts clutch wear, and keeps fuel results steady across different drivers.
Q: Does the China VI DPF clog often?
Not if you use it right. The system keeps exhaust hot enough for passive regen during normal driving. Let active regen finish when it starts. Use low-ash oil and good diesel – it'll run fine.
Q: What's really different between the tractor and tipper chassis?
Tractor: light, efficient, small axle ratios, single-reduction axles, built for highway and fuel saving.
Tipper: heavy-duty, hub-reduction axles, double-layer frame, tall tires, built for off-road punishment.
Pick the one that matches your real daily work.
