By controlling the extension and retraction of the cylinder, it provides stable support for the rear of the inspection vehicle, ensuring that the vehicle maintains a stable posture in complex terrains and varying working conditions. This design not only enhances the overall stability of the inspection vehicle but also improves safety during operations, allowing personnel to conduct bridge inspection and maintenance work on a more stable platform. Additionally, the precise control and stable performance of the rear stabilizer cylinder provide strong support for the accuracy and reliability of the inspection results.
