ISO 9928-4:2015 Jib Crane Operation Manual Guide
ISO 9928-4:2015, "Crane Operating Manuals — Part 4: Jib Cranes," establishes the standard for preparing operating manuals for jib cranes. It defines the content framework, formatting guidelines, safety warnings, and update management requirements, ensuring operators receive complete, systematic operating instructions.
Manual Content Framework
A jib crane operating manual must cover the following: foreword, application scope, target model, and version number. Safety instructions with jib crane-specific hazard warnings, including boom kick-back prevention, luffing operation limits, and wind speed restrictions. Technical specifications covering lifting capacity, load-radius curves, lifting height curves, portal base clearance, and tail swing radius. Installation instructions with transport requirements, assembly steps, bolt pre-tightening torque, and commissioning procedures. Operating instructions for hoisting, luffing, slewing, and traveling mechanisms, along with safety precautions. Special working conditions, including heavy-lift operations, marine applications, and multi-crane coordination. Inspection and maintenance schedules covering daily, monthly, and annual checks, lubrication charts, and wear parts lists. Fault elimination for jib crane-specific issues such as abnormal luffing, slewing bearing noise, and unstable hydraulic system pressure.
Formatting and Layout Requirements
A4Perfect-bound or loose-leaf pages, bilingual Chinese-English, body text ≥9pt with 1.5 line spacing. Three-level safety warnings: danger in red with white text, warning in yellow with black text, and caution in blue with white text, all aligned with ISO 7010 Safety signs standard. Operating steps written in imperative sentences with numbered sequences. A quick reference table for emergency operations placed inside the front cover, covering jib crane-specific emergencies such as hydraulic pressure loss, emergency boom lowering, boom kick-back, and emergency anchoring during excessive wind speeds. Tables numbered with captions, figures numbered with captions, and page numbers/total pages on every page. Electronic PDF version identical to the printed version.

Emergency Quick Reference & Updates
Jib cranes have specific emergency procedures. If hydraulic pressure is lost, the emergency lowering system engages, using a manual hydraulic pump or accumulator to bring the load safely to the ground. If the boom kicks back, a mechanical anti-tip device locks it in place. When wind speed exceeds the limit, press the emergency stop, then lower the boom to its minimum working radius and anchor it. If equipment is modified, an updated manual is issued within 90 days. The Kelude Heavy Industry Jib Crane Operation Manual is prepared in accordance with ISO 9928-4.

FAQ
Q: What special sections are included in the Jib Crane Operation Manual?
A: The safety instructions cover luffing operation limits to prevent boom tip-over, along with wind speed restrictions. The technical specifications include the lifting capacity/load-radius curve, clear height of gantry, and slewing tail radius. Special working conditions provide dedicated operating procedures for heavy-lift hoisting, marine operations, and multi-crane coordination.
Q: What are the formatting requirements?
A: A4 bilingual Chinese-English text at ≥9pt. Safety warnings use a three-tier color system: red, yellow, and blue. Operating steps are numbered imperative sentences. A quick reference table for emergencies is placed inside the front cover, covering boom-specific situations such as hydraulic pressure loss and wind speed exceedance.
Q: How are boom-crane-specific emergency situations handled?
A: In the event of hydraulic pressure loss, the emergency lowering system uses a manual pump for slow descent (speed ≤50% of rated). The anti-tip device locks the boom against rearward overturning. If wind speed exceeds limits, the boom is lowered to minimum radius and anchored. The Kelude Operation Manual includes a quick reference for all emergency procedures.
Q: How is manual version control managed?
A: A revised edition is issued within 90 days of any equipment modification, and users must return outdated copies within 30 days. Version updates are synchronized across all documentation. Kelude provides bilingual Chinese-English manuals with lifetime update support.
