HSE Web Communities Construction Discussion Forum. Hi Ian,BS 7. 12. 1 sets out the necessary requirements and Part 4 Lorry Loaders will be revised later this year consultation draft already out I believe. To argue your lift was less complex lesser risk than a crane lifting say a precast concrete floor unit into position would be foolhardy. I would say you were correct in your line of query and should look to methods of risk reduction for other such lifting operations. Regarding the previous replies, I agree with them all to some degree, but the one area which is generally ignored in such situstions inc. Please take a minute to read my previous posting on this topic. Mobile Crane Lift Planning How To Ensure Adequacy of Ground Conditions Hardstanding Area to Prevent Stability Issues Overturning by Mike A on 2. Nov 2. 00. 8 1. 5 3. This summarizes problems currently experienced in the precast flooring industry amongst others and I think it would make interesting reading for you. The PFF Precast Flooring federation have just ratified some standard Lift Plan Templates which will be available as free downloads from their website shortly which may also help. Snap On Tools Alberta. A key element of the templates is to offer the contractor increased size outrigger mats to spread the outrigger loads to reduce overturning risk. Outrigger loadings are provided for both standard as travels with the crane lorry loader and increased size mats and the client is asked to confirm which alternative is acceptable following consideration of the ground bearing capacity of the hardsatnd area. Free Crane Lift Plans' title='Free Crane Lift Plans' />This has become a standard for the PFF due to the lack of timely information provision ground bearing capacity of the hardstand by the Principle Contractor. It would greatly help to have increased size outrigger mats on site for the duration of the project. This would offer a standard method of reducing the risk of overturning plant whilst undertaking lifting operations. It would also offer a method of spreading MEWP point loads which are comparabe with mobile cranes in terms of tonnes m. Crane Pick Plan TemplateA modular man handleable system exists called Alimats which provides 3m. The system comes with full safety documentaion and a toolbox talk is offered on delivery. This would enable you to instruct your Site Manager to use them for all lifts regardless how simple minor the operation may seem. Crane companies and sub contractors such as flooring and steelworkers can also provide increased size mats on request to similarly spread the outrigger loads during their operations or they could be intructed to use your increased size mats to reduce cost implications. I hope this has been of some help. Kind regards,Mike. Crane Lift Plan WorksheetTake no chances, and plan out your crane lift planning in order to raise it up confidently. Every lift needs by far the most careful management, and the most complex. Templates for Crane Imprintable. Download and Save Template. Always do a few trial runs on regular paper cut down to the same dimensions as your Crane. Crane Lift Plan Notification Requirements. PE stamp or proof testing as required by applicable. Critical Lift Plan Template' title='Critical Lift Plan Template' />Here is my posting of 2. PFF initiative. On this forum and others, I read posts demonstrating confusion regarding who is responsible for the ground hardstanding adequacy during Mobile Crane operations. Express Invoice Crack Serial. In addition the procedures surrounding mobile crane planning appear to lack consistency, partly due to a lack of clear understanding of this topic by both main contractors site management personnel and off site managers, who do not appear to be aware of the level of responsibility the Site Manager is being burdened with, on a regular basis. I hope to receive some thoughts on this topic for inclusion in a current review of this difficult issue by the Precast Flooring Federation Safety Committee. The aim is to discuss the issues raise awareness regarding planning implementation of lifting operations under LOLER and BS7. So who is responsible for the ground hardstanding adequacy during Mobile Crane operations The Main Contractor On the vast majority of projects, the Main Contractor has the contractual responsibility to provide and maintain adequate hardstanding areas as required to facilitate safe lifting when mobile cranes are on site. This is the case even if a Crane Company has been employed to undertake a Contract Lift or if a sub contractor is undertaking crane operations as part of their package and providing AP crane planning Lift Plans. The Crane Company If under CPA Hire, they are providing a crane and a competent driver only and will expect to see evidence of adequate planning by others prior to undertaking the works. If under Contract Lift, they will provide full AP crane planning inc. Winbuilder Projects. Lift Plans and the AP must satisfy himherself that the hardstanding area is adequate to withstand the planned outrigger loadings. The Appointed Person Regardless of who provides the AP to plan the lift e. Precast flooring package, they must again be satisfied that the hardstanding area is adequate to withstand the planned outrigger loadings. The key element to a safe lift in any event is the Appointed Person AP. They are trained amongst other things to plan the crane lift around site constraints proximity hazards and ensure the hardstanding is adequate to facilitate the lift. Problem 1 Very rarely is the AP informed of a definitive tonnes m. CPCS training courses from the Main Contractor. Because this information is not usually provided, the AP will provide the Main Contractor with the crane outrigger loadings in tonnes m. Main Contractor that the hardstanding will be prepared to withstand the stated outrigger loading. Your thoughts ExperiencesProblem 2 It is very difficult to obtain proper consideration approval of the planned outrigger loadings and the hardstanding suitability to withstand the tonnes m. In approximately 8. Site Manager, without referral for engineering consideration. Your thoughts Experiences Problem 3 In addition, it is increasingly common practice standard requirement for Precast Flooring Federation Member Companies to request a repeat confirmation of adequacy each and every time the crane rigs up prior to commencing lifting from a given position. This can put Site Managers in a difficult position on the day of the lift, given the fluctuating nature of ground conditions due to rain moisture content and often without a resident engineer on site to offer additional consideration. Your thoughts ExperiencesProblem 4 Some APs do not confirm the size of the outrigger mats to be used with the crane and the resultant tonnes m. They may state the outrigger loading simply in tonnes, which is of no use to the site management team engineer in determining adequacy of the hardstanding e. Your thoughts Experiences Problem 5 The lifting operation may be expertly planned by the AP, but with inadequate consideration of the hardstanding bearing capacity e. Site Managers signing off the hardstanding without requesting engineering input, the lift still may not be safe. Your thoughts Experiences Problem 6 Should there be problems with crane stability sinking outriggers during the lift, the AP will be criticized for not having sought evidence of engineering consideration when obtaining his confirmation of ground adequacy. How practical is it to expect APs who in the main are not geotechnical engineers after all to decipher comment judge upon engineering input offered by the main contractor. How far should we as an industry expect APs to go, in order to be satisfied that the hardstanding is adequateYour thoughts Experiences I welcome any comments on the above, which as I mentioned earlier, will be relayed to the Precast Flooring Federation Safety Committee, as part of a review of the aforementioned which is currently underway.
