Standards Development
This international standard specifies general principles for users to define risk reduction measures for preventing hazardous events caused by wind. Then, the users consider the effect of wind on cranes at the place where cranes are installed and used on the basis of the general information on wind provided by manufacturers. Design of cranes on wind load is not included in this standard and principles for each specific model of cranes may be prepared in part 2 to part 5.
Proposer (Japan) explained the background of development in the annual meeting at Tokyo, Japan as follows and it was agreed development as TC96/SC5 Resolution 327/2017.
Background
- In most of crane accidents caused by wind, many users do not understand systematically and quantitatively the relations between cranes and wind.
- In issued ISO standards on the design of cranes, wind related structural and mechanical contents are prescribed systematically.
- There exist some ISO standards on safety measures by users for wind However, not enough
- It is difficult that the users understand the contents of standards and applies them on actual safety measures, because various related expressions are used in various standards and not enough information.
