Whilst you probably operate knuckle boom lifts every day that you’re at work, many people simply forget that they can be quite dangerous. Operating one of these machines when it’s windy, for example, can be a deadly mistake. It is essential that you determine whether the wind speed is too dangerous prior to getting into your lift and commencing work. In this article, we have aimed to outline the different wind situations you may encounter.

0 – Calm
When the speed is less than 1mph, it is perfectly safe to operate your machine. The area will be quite calm – smoke, for example, will rise vertically and there won’t appear to be any wind at all.

1 – Light Air
When the speed is between 1 and 3mph, it is safe to operate your machine. You will be able to determine the direction of the wind by smoke drift, but it won’t affect weather vanes.

2 – Light Breeze
When the speed is between 4 and 6mph, it is safe to operate your machine. You will be able to feel wind of your face, you will notice leaves rustling and weather vanes will be affected.

3 – Gentle Breeze
When the speed is between 7 and 10mph, it is safe to operate your machine. You will notice that leaves and even small twigs are in constant motion and that light flags will billow slightly.

4 – Moderate Breeze
When the speed is between 11 and 16mph, it is safe to operate your machine. You will notice that the wind raise dust and loose papers, as well as small branches being moved slightly.

5 – Fresh Breeze
When the speed is between 17 and 21mph, it is becoming unsafe for most knuckle boom lifts to be operated. You will notice small trees beginning to sway and the wind can cause crested wavelets on inland waters.

6 – Strong Breeze
When the speed is between 22 and 27mph, it is unsafe for any machine to be operated. You will see large branches being buffeted and umbrellas can only be used with great difficulty.

7 – Near Gale
When the speed is between 28 and 33mph, it is unsafe for machines to be operated. You will see whole trees in motion and will feel some resistance when walking against the wind.

8 – Gale
When the speed is between 34 and 40mph, it is unsafe for machines to be operated. You will notice twigs breaking away from the trees and that the wind generally impedes your progress.

9 – Strong Gale
When the speed is between 41 and 47mph, it is unsafe for machines to be operated. Some structural damage may occur and the wind is even strong enough to lift slate from rooftops.

10 – Storm
When the speed is between 48 and 55mph, it is unsafe for machines to be operated. These sorts of winds are rarely experienced on land, but trees could be broken or uprooted.

11 – Violent Storm
When the speed is between 56 and 63mph, it is unsafe for machines to be operated. These sorts of winds are generally experienced on the water – expect high waves and reduced visibility.

12 – Hurricane
When the speed is above 64mph, it is unsafe for machines to be operated. These sorts of winds are generally experienced on the water – expect high waves and white sea with driving spray.

Beaufort Scale of Wind Force
These recommendations have been based on the Beaufort Scale of Wind Force, which is internationally accepted and is used to communicate the current or expected weather conditions. The scale consists of numbers from 0 to 12, each of which represents a certain strength of wind. These calculations are based on a knuckle boom lift that is 33 feet (10 metres) above ground or in the open. The scale can be used to assess whether it is safe to proceed or not.
