It enables one-stop vehicle inspection and maintenance: the gantry lift stabilizes and elevates vehicles for easy chassis access, while the road simulator reproduces diverse road conditions (bumpy, curve, high-speed). This eliminates frequent vehicle movement, saves time, and allows visual observation of chassis parts’ dynamic performance during simulation—accurately locating faults (e.g., abnormal noise, suspension issues) without on-road testing, ensuring safety and efficiency. It fits most models and meets needs like post-repair verification and PDI inspection.
