Step by Step Guide to Overhead Crane Self Inspection

In the overhead crane maintenance system, daily inspections, regular servicing, annual load testing, and professional certification inspections are the four key components to ensure the safe and reliable operation of your equipment.

Daily inspections primarily focus on wire ropes, hooks, brakes, moving parts, and lubrication conditions. Regular maintenance involves lubrication, inspection of electrical components, load chains, slings, and other wear parts. Annual load testing ensures that the crane maintains structural integrity and functional performance under rated loads. Additionally, professional inspections—carried out by licensed technicians at least once a year—help identify potential issues early and provide repair recommendations. A well-executed overhead crane maintenance plan not only boosts equipment reliability but also significantly extends its service life.

During daily operation, you can refer to the overhead crane maintenance checklist we provide to perform routine checks yourself. If any issues are identified during inspection, there’s no need to worry—we’re here to provide professional maintenance service and support, whether your equipment is within or beyond the warranty period.
