Once a crane leaves the factory, it typically goes through a running-in period of approximately 60 hours. This phase is crucial for ensuring smooth operation and extending the machine's lifespan. The manufacturer usually defines this period based on the crane’s technical specifications and initial usage conditions. However, many users are either unaware of these requirements or choose to ignore them due to time constraints or the desire for quick returns. Some even believe that manufacturers will handle any issues, leading them to overload the crane during this critical phase. This can result in frequent breakdowns, reduced efficiency, and delays in operations. The running-in period has several key characteristics: 1. High Wear Rate New parts often have rough surfaces with limited contact areas, making them prone to rapid wear. As the machine operates, small metal particles from friction act as abrasives, accelerating the wearing of mating surfaces. If overloaded, this can lead to early mechanical failure. 2. Poor Lubrication Due to tight tolerances and uneven gaps in newly assembled components, lubricants may not form an effective film on friction surfaces. This leads to poor lubrication and increased wear, especially in precision parts. In extreme cases, it can cause scratches or damage to critical components. 3. Looseness Parts may experience loosening during the initial use due to vibration, heat, and stress. This can affect performance and lead to further damage if not addressed promptly. 4. Leaks Vibration and heat can cause seals and joints to loosen, resulting in oil or water leaks. Some hidden defects from manufacturing may only become apparent during this phase, causing unexpected failures. 5. Operational Errors New operators may not fully understand the machine’s structure or functions, increasing the risk of errors and potential accidents. Proper Use and Maintenance During the Running-In Period 1. Operators should receive proper training from the manufacturer and understand the crane’s structure, function, and maintenance procedures before operating it. Always follow the manual’s guidelines for operation and maintenance. 2. Keep the load within 80% of the rated capacity during the running-in period. Avoid long continuous operations to prevent overheating. 3. Monitor all instruments regularly. If any abnormalities occur, stop the machine immediately and address the issue before resuming operation. 4. Check the levels and quality of lubricants, hydraulic fluid, coolant, brake fluid, and fuel frequently. Ensure all seals are intact and maintain proper lubrication at every lubrication point. 5. Keep the machine clean and inspect it regularly. Tighten any loose parts to avoid wear or loss of components. 6. At the end of the running-in period, perform a full maintenance check, including oil changes and system adjustments. In summary, the key principles for managing the running-in period are: proper training, controlled workload, regular inspections, and adequate lubrication. By following these steps, you can significantly reduce early failures, extend the crane’s service life, improve operational efficiency, and ultimately maximize your investment.
