Frequently Asked Questions (FAQ)
Q: Who is responsible for establishing crane safety operating procedures?
A: Under the Special Equipment Safety Law and TSG Q7015 requirements, the user unit's safety management department is responsible for developing Safety Operating Procedures. These procedures cover inspection checklists, operational workflows, the Ten No-Lift Rules, and safety device maintenance. The procedures are revised every two years, and all operators must undergo training assessment and sign off after each revision.
Q: Where do I apply for a crane operator certificate?
A: The crane operator certificate (Q2 license) is issued by testing organizations authorized by the local Administration for Market Regulation (formerly the Bureau of Quality and Technical Supervision). The process involves registration, training, a theoretical examination, and a practical skills test before the certificate is issued. The certificate has a validity period of 4 years, and renewal must be completed within 3 months before expiration. Operating without a valid certificate is illegal and, under Article 86 of the Special Equipment Safety Law, may result in fines and a work stoppage order.
Q: How often should crane safety inspections be performed?
A: Safety inspections follow a four-tier schedule: ① Pre-operation checks (15 items, before each shift); ② Weekly checks (wire rope lubrication plus limit switch verification); ③ Monthly/quarterly maintenance inspections (brake, gearbox, and electrical system checks); ④ Annual comprehensive inspection (TSG inspection plus a 125% static load test). The user unit must maintain complete inspection records and retain them for at least 5 years for audit purposes.
Q: What does routine crane maintenance include?
A: Routine crane maintenance follows a five-tier cycle. Daily: visual inspection plus no-load test run; Weekly: apply specialized wire rope lubricant, check for wire breaks, and verify limit switches; Monthly: adjust brake clearance and grease motor bearings; Quarterly: replace gearbox oil, measure main girder camber, and recheck rail straightness; Annually: weld inspection, insulation test, and 125% static load test. For detailed maintenance intervals and operating standards for each component, refer to our crane maintenance manual and overhead crane routine maintenance articles on this site.
