Hi there,
Can anyone advise if it a legal requirement to have a wind detector on a mobile crane. I had always assumed it was but a friend of mine (Crane Driver) was stuck between rock and hard place other day as 2 safety officers argued over whether is was or wasn't in front of him and stopped him working for 2.5hrs.
He has asked me to find out for him but I cant seem to locate anything on the net. All help gratefully received.

i would have thought some means of measuring the weather should be available whether it is fixed to the crane or hand held. Even when operating MEWP outdoors you need some means of measuring the wind speed. They do give you guidance on how trees are moving etc. but a bit hit and miss. Of course the wind speed at ground level can be totally different at the jib head.
How does your friend decide when it is to windy for him to work safely, Why doesn't he know the answer. I would want some way of measuring it myself if i was in his situation. Mobile cranes i have certainly seen fitted with wind speed monitors so would be surprised if it wasn't required on cranes.

Cruden I am no expert on cranes but the wind detectors are mentioned in the ACoP for LOLAR 1998 with regard to Regulation 4 (1) – (2). To avoid the moderators wrath if I cut and past I would offer the following. You can view the ACoP on the HSE books web site http://www.hse.gov.uk/pubns/priced/l113.pdfThe Regulation is on page 17 and the ACoP paragraph is on page 21. The usual disclaimer applies to ACoP requirements. Brian

Hi,
Just to add to the above BS7121(I think) the Code of Practice for Safe Use Of Cranes recommends that an anemometer is fitted on the crane at a suitable point to measure wind speed and also that a hand held anemometer is available where necessary.
Regards
Steve

I think there is no definitive answer to a legal requirement , but a thought as most manufacturers do have one fitted and you have to maintain the crane to manufacturers standards then in that sense yes they do.

BS7121 deals with the Safe Use of Cranes.
Section 18.3 of BS7121 Part 1:2006 (General) deals with 'Wind speeds' and states "In the case of cranes positioned where they could be adversely affected by high winds an anemometer should be located/mounted at a suitable point(s), preferably on the crane structure and supplemented with hand held anemometer(s), where necessary".
Section 8.8.4 of BS7121 Part 3:2000 (Mobile Cranes) deals with 'Means to check wind speeds' and states "The appointed person should obtain information on wind conditions prior to starting a lifting operation (e.g. by obtaining a local weather forecast or by using an anemometer)".
