To ensure the precision of guardrail post installation, the guardrail pile driver's travel slide way has a small clearance. Due to long-term outdoor construction, exposure to wind, sand, and dust makes it difficult to maintain the uniformity of this clearance. Grease does not easily form a uniform oil film on the friction surface, reducing friction and wear. The lubrication effect is significantly diminished. In the initial stages of use, due to the impact of alternating loads from the hydraulic hammer, vibration, thermal deformation, and other factors, components that were originally tightened may loosen, leading to early abnormal wear of the travel slide way components. In severe cases, this can lead to scratches or seizing of precision-fit components' surfaces, causing malfunctions.

To prevent poor lubrication of the travel slide way and the occurrence of faults, it is recommended to regularly maintain the guardrail pile driver's travel slide way, replenish grease, and ensure the effectiveness of its lubrication. It is hoped that everyone will pay attention to these details to extend the machinery's life and improve economic benefits.
