A roadheader is a highly efficient and safe piece of engineering machinery widely used in mining, tunneling, subways, and other fields. It employs a rotating cutting head or drill bit to break and excavate rock or soil, enabling rapid and efficient construction progress. However, like all machinery, regular maintenance is essential. So, how often should a roadheader be maintained?

　　The maintenance cycle of a roadheader varies depending on its model, usage frequency, and working environment. Generally, "daily maintenance" should be performed to ensure the equipment operates normally. This includes checking lubrication oil, fasteners, electrical systems, and other basic components.

　　For "more in-depth maintenance", such as replacing worn-out parts and inspecting key systems (e.g., the hydraulic and cooling systems), the schedule typically follows the manufacturer's recommended maintenance plan. This can range from several hundred to several thousand operating hours. For example, some components may require inspection every "500 hours", while critical parts might need a major overhaul every "2,000 hours".

　　If a roadheader is "left idle for an extended period", it should be started periodically, and essential system checks should be conducted to prevent damage due to prolonged inactivity.

　　The specific maintenance cycle should always refer to the manufacturer’s maintenance manual and be adjusted based on actual operating conditions. Regular professional maintenance not only extends the equipment’s lifespan but also prevents potential failures, ensuring construction safety.
