3.7.1 Working in windy conditions
The variation of wind speed can lead to many problems such as vehicle stability, the oscillation of the load, reduced visibility due
to dust rising and leaves etc.
Other unfavourable factors for using the vehicle are:
• Site location: the aerodynamic eff ect of buildings, trees and other structures lead to an increase in wind speed.
• The height of the extended boom: the more it rises vertically, the faster the wind speed.
• The load clearance area: the more area it occupies, the greater the eff ect of the wind.
 HIGH WIND
The DIECI telescopic handlers can be used up to wind speed of 45 Km/h equal to 12.5 m/s (N°6 on the Beaufort scale) measured
on the ground.45 Km/h
At a temperature of 10°C , a wind speed of 32 Km/h means a temperature of 0°C is perceived on exposed parts of the body. The
higher one goes, the more the wind speed increases and the greater is the sensation of a drop in temperature.
 DANGER
Never lift loads with surfaces smaller than 1 m² in the presence of a fresh breeze (n°5 on the Beaufort scale).
Below fi nd the graphics of the Beaufort scale in order to indicatively determine the wind speed at which work is being performed
and therefore suspend the work operations if these determined values should be exceeded.
Beaufort Wind Scale
N° De nition Indicators Speed (m/s)
0 Calm Smoke rises vertically 0 - 0,2
1 Light air Smoke drift indicates wind direction 0,3 - 1,5
2Light breeze
Wind felt on exposed skin. Leaves rustle and wind vanes
begin to move
1,6 - 3

Leaves and small twigs constantly moving, light fl ags
extended

Dust and loose paper raised. Small branches begin to
move
5 - 8

Small trees in leaf begin to sway. Moderate waves of some
length

wires. Umbrella use becomes diffi cult

wind
