ISO 9374-9:1994 Standard for Bridge Crane Information
ISO 9374-9:1994, "Cranes — Information to be provided — Part 9: Overhead travelling cranes," defines the scope of technical information that manufacturers must supply with an overhead crane. The standard specifies the format and content requirements for nameplate data, technical specifications, the operation manual, installation drawings, and the spare parts list.
Nameplate & Technical Specifications
The crane nameplate must include the manufacturer's name, model and serial number, year of manufacture, rated lifting capacity, span, lifting height, work duty classification, and the applicable design standard. It is made of stainless steel and fixed in a prominent position on the end of the main girder. An operator cabin is equipped with a duty chart, load capacity chart, and lifting height curve. Key technical parameters should cover overall dimensions, trolley gauge, wheel base, maximum wheel load, dead weight, working speeds of each mechanism, and motor power. The technical specifications table must list working speeds for each speed step along with the corresponding load spectrum. Every Kelude overhead crane ships with a complete technical file package.
Operation Manual & Installation Drawings
The operation manual is prepared in accordance with ISO 9928-2 and covers five main sections: safety instructions, technical specifications, operating instructions, inspection and maintenance, and fault elimination. Installation drawings include the rail foundation plan, rail installation tolerance requirements, electrical wiring diagram, and earthing system diagram. The maintenance manual covers routine care, periodic maintenance, lubrication charts, and the wear parts list. The spare parts list covers critical spare parts for a minimum of 10 years, with a spare parts inventory availability rate of at least 80% and 24-hour dispatch for urgent orders. Kelude provides lifetime technical support to all customers.
