Focusing on steel rail bolt maintenance for railway track maintenance depots and heavy‑duty machinery depots, we deliver an all‑weather, fully‑automatic, high‑precision and traceable bolt‑operation solution. It addresses the drawbacks of conventional manual work including low working efficiency, high operational risks, insufficient precision and troublesome data management. Equipped with an embedded intelligent detection and operation system, the device modularly integrates an electric wrench and an intelligent detection module. Fitted with high‑precision sensors, a floating working platform and an intelligent control system, it can automatically identify, locate, fasten or loosen rail bolts, inspect bolt status and transmit data back. It constitutes a new‑generation intelligent railway‑maintenance equipment that replaces traditional manual bolt‑handling work.
