Posted By Brian Jones Do any of you, out there, have any suggestions on controls for the task of attaching slings on to the crane when loading or unloading large containers on or off articulated transport? How can we safely gain access onto the container and once up there how can we make the area safe to work on. Erecting handrails seem to be a non starter and there are no obvious points to attach a fall arrest lanyard onto. We’ve considered a MEWP but this seems to be over complicated? Just to complete the picture these containers are usually delivered onto site and contain tools and equipment for use by contractors. The project is usually very well covered by risk assessments/method statements, however, we always seem to miss out this aspect of the project.

Posted By RP A large forklift? Its the design. The usually excepted method is a suitable footed ladder for access. Consider using a long pole with a hook on the end to hook the sling and pull it towards the attachment point. This will will avoid the need to climb onto the container. Its worth a try.

Posted By Chris Pope stand on a ladder and don't get off to sling. Have the crane pull the hooks to you or have them on ropes so you can pull them to the corners before climbing the ladder

Posted By William i have done this offshore on a regular basis and most containers have a lifting shackel already fitted, which is long enough to be attached standing beside the container. i would think this would be the best way of doing things, always try to avoid any work at height.

Posted By Sean Nuttall Brian, I am assuming that you are talking about containers for use on site and that are delivered on the back of a flat bed vehicle and not a skeleton trailer specifically designed for hauling containers about If the above is correct then consider this. You can get the cabin supplier to position the container not directly on the flat bed trailer but instead raised up on a couple of skids such as railway sleepers or sections of 4 x 8. Then ask your crane company to bring with them a lifting beam suitable for lifting a container. That way nobody has to climb anything. Simple and it works.

Posted By Steve Johnson Brian Have you solved this one yet? I am also having great difficulty with this issue. I'm sure some who have claimed to have solved probably don’t see the operation on-site. We have our own cabins that are lifted either by haib or mobile crane so my problem is not just on-site by also in the yard. Double stacking not so much of a problem as you can attach an inertia block to the hook block of the crane/Hiab (attaching your harness), but single stacked cabins do not have enough clearance distance. Another problem I have is (and nearly all cabin suppliers have it) most Hiab drivers work alone, put them in a harness and you now have a problem with rescue. Pay for 2 men then you’ll never get any work! The idea of moving the ladder sounds great but does not work in practice as you can’t always get the ladder to all 4 leg positions and if you can you still have to get to the centre to get the chains (yes a rope can help). I have tried to think of ways of attaching the chains at a lower level (welding attachment points lower down on the jack legs etc.) But this does not work as the chains pull into the cabin causing damage. I’ve even asked the HSE for advise. The advice was “they could utilise a pole with a clipping system for attaching crane hooks and a hook / clip release system, like those used to lift sheet piles into place, etc.” (I’ve got a video clip of this device in action if you would like a copy, unfortunately it’s not on cabins but steel erection, and one of the steel erectors walks the top flange not very good for a safety device video) I’ve even considered leaving a set of chains/slings/wire bonds on each cabin but then you have to get up there every 6 months to inspect them. The Lifting frame sounds like a good idea but I can't see it working with a Hiab. I have some photos of double stacking cabins if you would like a copy. Please let me know if you have found something that works.

Posted By Howard I was watching one of our Hiab ops at work the other day & was more than impressed. In a similar way how Chris described, he attached slings to each chain leg prior to lifting, then centred the hook over the cabin. The extra length created by the slings allowed him to walk the chain hooks into position. A foldable ladder was used to reach the lift eyes to attach the hooks. Baz

Posted By Steve Johnson Baz Is this done every time? What happens if you can't get the ladder around all 4 points which i find all to often is the case? Steve
