Good afternoon,
I would really appreciate if someone could provide me with the above mentioned.
Some people say 8 ton, other 15. I would rather use 60% of the SWL of the lifting equipment. It seems that there is no set definition by a competent body.
For your information, Heavy Lift Operations are part of section 6A Offshore Operations - Specialised Activities of the Offshore Vessel Management and Self Assessment (OVMSA).
This states, for example, that "procedures are in place for the formal planning of all heavy lifts and their transportations, whether using crane, A-frame or lift vessel."
This implies a clear definition of what a heavy lift is.
Thanks very much in advance for your help regarding this matter.
Kind regards.

LOLER (free to download) makes references to BS 7121.
Both docs talk about:
Basic lifts
Standard lifts
Complex lifts
"heavy" (nor weights) are not really discussed, however I concurr with you that any lift exceeding 60% of the SWL of any equipment involved in the lift would trigger the lift being upgraded ( if thats the word) to a complex lift and as such needing a specific lift plan.

Thanks Walker for your prompt reply; this is well appreciated.
I have also had a look at LOLER and BS 7121 but, as you have noticed, there is not proper reference to a "heavy" lift.
I believe my best bet is to contact OCIMF and see what they tell me...

Sorry Pompie you are asking the impossible? Cranes can come with lifting capacity from 1 tonne to thousands of tons in some cases. Therefore no competent body could define what is or is not a heavy lift.
I would agree with the method you have come up with of 60% SWL.but I cannot see who could give a definitive tonnage answer to this, purely due to the varying crane and equipment capacities.(SWL)

I am with you, Alex.
I think it is non-sense to say that a heavy lift is anything above 8 ton or 15. Why not 12.58 instead?
The point is some of my colleagues have asked me the following: why 60% of SWL instead of 75% for example? Where did you get this from? LOLER? I have not been able to answer...
I have always seen this figure used to define some kind of complex lift but without any reference to any official document.
I have just sent an e-mail to OCIMF and I will let you know what they tell me.

I have heard of some companies stating anything more than 50% of lifting equipment be used as a guide but that was there company policy. I have never seen anything written down to determine where this figure came from nor been able to determine myself where it has came from. It would depend on your company policy on lifts and the equipment used to carry out the tasks.
Any lift that we carry out has a lifting plan showing weight calculations on each lifting point that are double checked and signed.
Another view is if you have a 250kg Loadstar motor and its lifting 220kg dymanic load then that could be classes as a heavy lift.

Try OGP Report No. 376 'Lifting and hoidsting safety recommended practice'. Appendix 1 gives an example lift categorisation scheme, including definition of 'heavy lift' as in excess of 90% of rated capacity'.

Hmmmm, 1000tonne crane so 400tonne is not a heavy lift.
Its a matter of planning all lifts with the detail based on the complexity. 20 tonne is peanuts in many industries. Do not get bogged down with trying to see if it is light, medium, heavy or whatever. Identify the hazards and control them as per the requirements of LOLER.

Thank goodness nobody has suggested that a heavy lift could be defined simply as the opposite of a light lift, as this might have led to a flurry of responses arguing about what constitutes a light lift!!!!
:-) :-) :-) :-) :-)
[multi-smileys added to emphasise that the above comments should not be taken too seriously. As my earlier attempts to post non-mutating mega-smileys on this forum failed, they've been abandoned in favour of multi-smileys! :-) ]

It is the opposite of a heavy lift so no problem there :-)

Thanks once again for your straight forward answer.
I think the original poster was in an offshore scenario.
Like you said use LOLER or any other system that controls and identifys the hazards to ensure you are using equipment capable of doing the task.

Good morning,
would you believe me if I tell you that OCIMF are not able to provide me with a definition of a "heavy lift"?
"... there is no definition of a heavy lift as it is difficult to quantify."
That was their answer. Now, they are taking the mickey!
These guys are using this term throughout section 6A of their Offshore Vessel Management and Self-Assessment but they do not know what it is.
It is a wee bit ironic, isn't it? Och well, I'll make my own definition of a heavy lift, hoping the OCIMF inspectors will agree with it...
