Complete Series on Crane Safety Operations: A Compilation of Operating Procedures, Safety Devices, and Maintenance Standards
📌 Complete Series on Safe Crane Operation This section covers safety operating procedures, maintenance of safety devices, routine maintenance, and standards and regulations. The comprehensive content includes pre-operation checklists, the “Ten No-Lift” principles, maintenance schedules for safety devices, routine maintenance procedures, and the GB/TSG standards system. This site has published 12 safety-related articles, which are compiled here for easy reference.
The core of safe crane operation is: daily pre-operation inspections → adherence to safe operating procedures → regular maintenance of safety devices → passing annual inspections. Proper daily inspections and adherence to operating procedures can reduce accidents resulting in 85% or more in casualties. Krud Heavy Industry has always adhered to a “safety first” philosophy in design and production; all cranes shipped from our factory are equipped with a full set of safety devices.

Frequently Asked Questions (FAQ)
Q: Who establishes the safety operating procedures for cranes?
Answer: In accordance with the *Law on the Safety of Special Equipment* and the requirements of TSG Q7015, the safety management department of the operating entity is responsible for formulating safety operating procedures, which must include inspection checklists, operating procedures, the “Ten Prohibitions on Lifting,” and maintenance of safety devices. These procedures must be revised every two years; following any revision, all operators must undergo training and testing, and sign to confirm their understanding.
Q: Where can I apply for a crane operator’s license?
Answer: The crane operator certificate (Q2 certificate) is issued by examination institutions for special equipment operators authorized by local Market Supervision and Administration Bureaus (formerly the Quality Supervision Bureaus). Registration → Training → Written Exam → Practical Exam → Certificate Issuance. The certificate is valid for 4 years; renewal must be completed 3 months prior to expiration. Operating a crane without a valid certificate is an illegal act; pursuant to Article 86 of the *Special Equipment Safety Law*, offenders may be subject to fines and ordered to cease operations.
Q: How often are crane safety inspections conducted?
Answer: Safety inspections are divided into four levels: ① Daily pre-operation inspections (15 items, before each shift); ② Weekly inspections (wire rope greasing + limit switch verification); ③ Monthly/quarterly maintenance inspections (brakes + gear reducer + electrical system); ④ Annual comprehensive inspection (TSG inspection + 125% static load test). The operating entity must establish a complete record of inspection logs and retain them for at least 5 years for reference.
Q: What does routine maintenance of a crane involve?
Answer: Routine crane maintenance is carried out according to a five-tier schedule. Daily: Visual inspection + no-load test run; Weekly: Apply specialized grease to wire ropes + check for broken wires + verify limit switches; Monthly: Adjust brake clearance + lubricate motor bearings; Quarterly: Change gearbox oil + measure main girder camber + recheck rail straightness; Annually: Non-destructive testing of welds + insulation testing + 125% static load test. For detailed maintenance schedules and operating standards for each component, please refer to the crane maintenance manual and the article on daily overhead crane maintenance on this website.
