Wind strengths when using working platforms

windvaneSince wind impairs work with aerial work platforms, platforms approved for outdoor use can usually be used at wind speeds of up to a maximum of 12,5m/s = 45km/h. Uses beyond this are not regarded as intended use. It is the operator's responsibility to check the maximum wind speed on the machine nameplate or in the manufacturer's operating instructions. The wind speed should definitely be measured in the basket/on the platform at working height. A wind speed measuring device (anemometer) must be used for this, which is available from us as safety equipment.

 

Overview of wind strengths (according Beaufort scale)

 wind strength designation Km / hr. m / sec. perception Access Platforms Use
0 still under 0 0-0,02 perfect wind calm Easy to use Green: Working platform application possible
1 quiet train 1-5 0,3-1,5 Smoke rises almost vertically Easy to use Green: Working platform application possible
2 Light breeze 6-11 1,6-3,3 For the feeling just noticeable, leaves are moved Easy to use Green: Working platform application possible
3 weak breeze 12-19 3,4-5,4 Leaves are moved, and likewise pennants Easy to use Green: Working platform application possible
4 moderate breeze 20-28 5,5-7,9 Pennants are stretched, small branches are moved Easy to use Green: Working platform application possible
5 Fresh breeze 29-38 8,0-10,7 larger branches are moved, for the feeling already unpleasant Easy to use Green: Working platform application possible
6 strong wind 39-49 10,8-13,8 larger branches are moved, wind can be heard in houses see manufacturer's limits Yellow: Working platform application restricted
7 stiff wind 50-61 13,9-17,1 weaker tree trunks are moved Can not be used Red: Working platform can not be used
8 stormy 62-74 17,2-20,7 large trees are moved by the wind, while going noticeable handicap Can not be used Red: Working platform can not be used
9 Storm 75-88 20,8-24,4 light objects are brought out of their position Can not be used Red: Working platform can not be used
10 heavy storm 89-102 24,5-28,4 Trees are overturned Can not be used Red: Working platform can not be used
11 hurricane storm 103-117 28,5-32,6 destructive effect of a severe nature Can not be used Red: Working platform can not be used
12 Hurricane 118-133 32,7-36,9 devastating effect Can not be used Red: Working platform can not be used
