Conventional techniques for those rules apply to each of the electric components, mechanical or structural component, this standard will not be repeated.
This standard safety requirements for regular maintenance to move in accordance with the manufacturer's instructions, working conditions, frequency of use and the state
Elevating work platform drafted.
If you have a mobile elevating work platforms were functional check before starting work each day, and all required control and safety equipment
We are ready and in working condition, or can not start a mobile elevating work platform up and running.
If a mobile elevating work platform is rarely used, can be checked before starting work.
Appendix A explains the choice Beaufort grade 6 as the reason for the highest wind speed.
This article cited a security paradigm, but this is not the only viable solution. As long as you can meet the relevant safety levels
All other possible risk reduction solutions are allowed.
Because you can not find a satisfactory explanation of the previous national standards for power factor of stability calculation, so the adoption of the European standard
Associate Committee (CEN) (formerly TC98/WG1) the results of the test results to determine mobile elevating work platforms suitable factor
And Method of stability. Test methods are described in Appendix B, may be higher or lower as desired and use of control operations Winds
Manufacturer's latest R & D results braking system.
Likewise, other lifting devices in order to avoid inconsistent criteria unillustrated wire cable coefficients occur, and attached to this document 5.5.2
Appendix C also suitably extract the German Standard DIN15020 widely accepted (all parts), Appendix D Another application example.
