View Full Version : Crash decks and alloy towers

21st January 2013, 02:55 PM
Anyone in UK know if the use of aluminium mobiles is banned from crash decks?
The WAH regs say that the working platform should be fit for the intended work. But what if the contractor wants to use mobiles on a crash deck for MEP works before a false ceiling is put in form the crash deck boarded level. Obviously the contractor doesnt want to pay for the boarded deck to be lowered as its a hanger that covers 15,000 square metres. The ally towers would be a metre or so high and extra handrails would be on the actual crash deck.

If it's only 1m off the floor why not use 1m trestles.

The crash deck will be suspended 22 metres high. They want to use low ally tower mobiles for work above the false ceiling. Its quite a large hanger and they dont want to pay for the boarded level to be dropeed for ceiling closure works after the mep works are done.

Cant see a problem using a 1m high tower off the crashdeck, but would suggest getting some lightweight (alloy) channel steels to run the wheels in and ensure that they dont drop through any boarded joints, done this successfully a number of times before Havespanner

Thanks Ray but it will have ply on top of the boards.I have been costing it today and have done the labour, transport, materials etc. The ply alone comes to about 70 grand.Got a bit of a headache when an HSE guy said the WAH regs say a working platform must be fit for the job and you cant put ally mobiles or even small hop up scaffolds on the main deck.

What about changing the use of the platform to support and use a mobile tower off it, its only 1m high for F*** sake its impossisible to go anywhere! as long as guardrails are sufficient. Just this change of use should solve the problem, then change usage back to original, extra paperwork buta lot better than all the labour to alter it.

Could do there will be a lot of mobiles on the whole deck as its 15,000m2. My main concern would be that the users dont overload it with materials.I already said extra handrails but this guy is being a bit of a prick. Its the main contractor who wants to use mobiles nothing to do with me.

As long as you inform them of the loading per square metre that cannot be exceeded and place this information on the platform so that it can be read by workers then it is then up to the main cantractor to regulate it after you have handed it over. Its excatly the same as any other scaffold. I understand your concern but you can't police every scaffold platform you have erected. I assume you hav had this designed so you will be able to provide the loading no problem.

Ray i am in the Gulf. It will be designed if I win the job. I obviously know loading is the users responsibility but you still worry about it. There will be a lot of tube and fittings hanging up there!!

If you get the job i'll come over and help you worry about it, 2 heads are better than one and its sodding cold over here, thought you were in Gulf.
Confidence in your work, it will be fine :bigsmile:

Ok no problem.The petrochemical industry is pretty well policed safety wise over here. The civil construction side is a different ball game altogether.
Its not that warm here drops to about 15 at night at the moment!!
