Posted By W P F On site, the client has had an incident where a 2 tonne SWL strop failed during a lift. The hook was a 3 tonne SWL and had no damage to it on inspection. Is the strop regarded as lifting equipment, or do we only think that under RIDDOR the jib, crane etc is the equipment. Our site team believe there is an 'accessory' to which they would allocate a strop to and 'equipment' difference. Any thoughts please. Thanks WPF

Posted By Robert K Lewis If it intended that the strops are to be used as the load fixing point for lifting then they are covered by LOLER and are equipment. If however thay are merely holing the load together in a stable position then they aree work equipment. The decision to use the strops means that the site team have de facto turned themm into lifting equipment and this must then be designed, tested etc as suitable for purpose Bob

Posted By justgossip I presume that the strop was supporting the load. LOLLER applies. All our strops have a certificate of inspection and test. We don't send them for a re test, after 6 months, in the bin and buy new, hence new certificate. garry

Posted By David Matthew Personnally I would have thought they were lifting accessories in the same way that chains are. Regards David

Posted By Phil Grace WPF As previous poster stated if it was being used to lift object/load rather than simply bind/hold/contain them then it is lifting equipment. Banding that is used e.g. to hold a pack of timber together is not lifting equipment but then again the pack should not be lifted using the banding. But am I missing something - you stated that the stroop had a 2tonne SWL - if it has been tested and given a SWL then surely it must be lifting equipment...?? Phil

Posted By Andrew W The strop is definitely an accessory and as such should have a cert dated within the last 6 months. Lifting equipment refers to anything which is permenantly attached to the crane ie hook upwards. Andy

Posted By Colin Reeves Concur totally with Andy - the strop is a "lifting accessory" under LOLER Colin

Posted By Mark Mace Please forgive my ignorance, i assume by the word STROP you are referring to a "material strap" with loops on each end. Please can you clarify as all definitions that i have been able to find for STROP are "short lenghts of leather strips" mainly used for sharpening blades (eg as one might sharpen a razor in a barbers)

Posted By D H I always understood that lifting equipment was classed as everything leading to the hook. Accessories are things that attach to the hook. This would make the strop an accessory? Therefore not reportable under RIDDOR? Dave

Posted By Andrew W Strop is a slang term within the lifing fraternity for nylon lifting slings. (yep they're an accessory)

Posted By Mark Mace ok i get the terminology now, however as the strop or strap was lifting the load then surely it becomes a part of the lifting equipment and therefore it is reportable under RIDDOR regulations. One other question if the strop (strap) was certified for 2tonnes swl then what was the weight in the actual load. It is possible for any certified equipment to fail at any point in time, what emergency plan was in place for the possibility of failure, i personally would insist for a 2 ton load to have 2 x 3 ton straps therefore if one failed the other would negate the effect of the failure of the 1st, and you still have a 50% safety margin on the single strap.

Posted By Bob Youel if we ended up in court a layperson jury member would use common sense and call all parts of something that lifted something irrespective of the hook up or the strop down arguement 'lifting equipment' and draw conclusions from there we can nit pick all we like but something that is attached to a hook and is also attached to a suspended box etc is lifting that box if the hook rises up into the air so we need to have the appropriate management system in place!

Posted By Alan Nicholls If you are using chains slings,hooks shackles or eye bolts. They are classed as Lifting Tackle or Lifting Gear. Lifting equipment refers to the device used to do the lift. The chances are the strap failed because its swl was exceeded. By doubling the strap, or by using several anchor points you can reduce the chances of failure. All accessories are tested far beyond the swl stated. Chains slings strops cables, horses for courses. It all comes back to competence and training. Reagards Alan

Posted By Colin Reeves There seem to be a lot of opinions being expressed with many saying that strops are clearly lifting equipment as they are part of the equipment used for lifting. Whilst this may seem logical, the law disagrees and you should make it clear that lifting equipment is your version of the truth. SI 1998 No 2307 The Lifting Operations and Lifting Equipment Regulations 1998 states in Regulation 2(1) that: "lifting equipment" means work equipment for lifting or lowering loads and includes its attachments used for anchoring, fixing or supporting it; and that "accessory for lifting" means work equipment for attaching loads to machinery for lifting From these it is absolutely clear that a strop is an "accessory for lifting" and definitely NOT "lifting equipment". The thorough inspection regime for each is different - essentially equipment is annual, accessory is six monthly (Reg 9(3)(a)). Detail is more complex but that is a simple summary. Colin

Posted By Flic On the other hand, this question is about the application of RIDDOR. The words in the schedule are: 1. The collapse of, the overturning of, or the failure of any load-bearing part of any - (a) lift or hoist....... This does not make a distinction between equipment and accessories, but is a much more pragmatic criterion. Flic

Posted By markh1965 Seen this and had to answer. I am a registered tester and examiner of lifting equipment with the lifting equipment engineers association and with 20 years experience in the industry. A webbing sling or strop is an accessory and msut have a valid certificate and serial number on it and if the 2 tonne strop was in good condition it would have taken 12 tonne to break it unless there was a cut in it. Check out SPANSET Ltd in Middlewich,Manchester they have a good web sit with different angles slings can be used in and there various swl's. The lifting industry rule is anything below the hook is accessory and above is lifting equipment. Hope this helps

Posted By Paddy Tomlinson As far as I was aware webbing slings or "strops" have a factor of safety of 7:1 therefore a 2 tonne sling should not part unless there is 14 tonnes of load, unless as previously stated it has been damaged. The question that needs to be asked along with whether it is reportable is how on earth did the failure happen in the first place and what is being done to prevent it from reccuring

Posted By steven bentham W P F Hopefully you have worked out the answer to your question. Perhaps you could post the reasons why the sling failed for information for the rest of us. If you have not looked at Marks suggestion for the web site of SpanSet Ltd, its a very interesting site. Come on tell us what happened during the lifting operation, the suspense is too much!!!

Posted By W P F For you all, the information to hand was that our Client (Under CDM) was conducting their own lift, with the strop being 2t SWL and the hook 3 tonne SWL - the lift had commenced and the weight was being born by the hook and strop, just mm from the ground. The strop failed and the load returned the couple of mm to the ground. No injuries or anything occurred and the Client identified it as a Near Miss in reporting. The Lifting Team had taken all relevant steps, planning and implementing the safety measures accordingly and clearing the path of obstruction and personnel. Lifting alarm sounded, took the weight and bobs your uncle, the failure. Strop failed, looked at the hook and there was no visible damage, but further testing being completed. Load was approx 50% of SWL so the issue wasn't over loading. As the client seemed to surpress the potential of the incident and downgrade to a near miss, I was a little surprised and that is why I asked for clarification on RIDDOR and the accessory/equpment issue on the strop. Thanks all, will look at the relevant website. Regards WPF

Posted By ttownshend Lifting strops come under LOLER Regs and are therefore subject to inspection before every use, and every six months. They should be tagged with the date of last inspection and date next due. (Classed as equipment below the hook as opposed to above the hook, which should be inspected every twelve months)

Posted By Paddy Tomlinson W P F You said "Strop failed, looked at the hook and there was no visible damage, but further testing being completed. Load was approx 50% of SWL so the issue wasn't over loading." Therefore the sling being used must have been damaged in some way. If the appropriate pre-use checks had been carried out this should have been identified and the sling taken out of service. Without being nasty I think this is calling the competence of the lifting team into doubt as it would suggest that either the checks were not carried or they were carried out incorrectly. The question again is what is being done to prevent recurrence. Paddy
