How often should tower cranes be inspected?

The inspection cycle is once a year. Inspection cycle regulations: Article 5 of the "Rules for Periodic Inspection of Lifting Machinery" approved and promulgated by the General Administration of Quality Supervision, Inspection and Quarantine stipulates: The periodic inspection cycle for in-service lifting machinery: tower cranes, lifts, and mobile cranes are inspected once a year; among them, rubber-tired gantry cranes are inspected once every 2 years. Inspection scope: The scope of inspection mainly includes checking whether components are damaged, whether damaged parts have been replaced, whether the condition of the tower crane can ensure the safety of construction personnel, and whether the parts involved in the construction process have been painted. If the paint peeling is severe, there may also be a risk of facing fines.

I frequently work on construction sites and pay special attention to equipment safety. The inspection frequency for tower cranes is crucial as it directly impacts the safety of on-site personnel and project progress. Generally, inspections are not fixed; they depend on usage intensity and environmental factors. The most basic is the pre-operation daily check, such as inspecting for cable wear or loose bolts every morning, which only takes a few minutes. Then there are periodic professional inspections—large sites may require monthly checks, while smaller projects can extend to quarterly inspections, where professionals use instruments to assess structural integrity and load-bearing capacity. For older equipment or after severe weather, inspections should be more frequent. Additionally, regulations mandate an annual comprehensive certification inspection to ensure all components meet safety standards. Neglecting these can lead to severe consequences, such as collapses or accidents. I advise fellow workers to develop a habit of documenting inspections to prevent issues before they arise. In short, safety comes first—never cut corners.

Speaking from my hands-on experience with tower cranes after years on construction sites, inspection frequency is never rigidly fixed but depends on daily needs. Each piece of equipment is different: new cranes might get quick biweekly checks for the first few months to verify hydraulic systems and sensors, but before each workday starts, I always conduct routine inspections of critical components like foundation stability and signal lights—sometimes just visual and tactile checks taking minutes. During tight schedules on major projects, bosses often require additional monthly professional team inspections covering electrical and mechanical parts to prevent minor issues from escalating. Inspections intensify during bad weather or overtime work. Personally, I find excessive inspections waste time while infrequent ones pose risks—monthly checks strike the right balance. Remember these tips: operators should maintain equipment daily rather than relying solely on others; aging parts need prompt replacement after prolonged use—better safe than sorry. Adopting these practices makes projects run far smoother.

With years of experience in equipment maintenance, I'd like to discuss the technical aspects of tower crane inspection. The core focus is structural safety: the crane's mast, jib, and foundation must be inspected quarterly using non-destructive testing methods to assess cracks or deformations. Critical components like wire ropes and bearing systems require daily lubrication and visual inspection, with immediate action taken upon detecting wear. The control system should be verified monthly using test instruments to check electrical connections and sensor accuracy. Regulations typically mandate an annual comprehensive inspection, including load testing and certification reports. Inspection frequency also depends on usage time: an internal inspection is required after every 100 cumulative operating hours. In practice, adjustments are made based on equipment age—older cranes undergo more frequent inspections, while newer models may only need annual checks. Preventive maintenance outweighs post-failure repairs, so it's advisable for all construction sites to establish standardized inspection procedures. Simply put, consistent daily attention ensures long-term safety.
