CE Mark of Aviation Maintenance Trailer with Elevation Accessories (Jacks)

[ikerg]

My company is manufacturing a trailer for some aircraft engine maintenance operations.
The engine is supported by some Arms, but for specific operation the trailer has to be lifted 70cms from the floor in order to give room enough to the staff for the operations.
This lifting operation is carried out by 4 landing gear jacks, commonly used on the semi-trailers and tandem trailers.
The Jacks are not CE Marked
In order to comply with the CE requirements and the whole machine (trailer) be CE marked, should the Jacks and all the elevation accesories be as well CE Marked?

on the CE Directive (2006/42) is stated that all the elevation systems should be manufactured against the WLL witht a ReserveFactor>=4
As we don't know which is the Manufacturer's limit (not CE mark) we did the jacks selection based on supporting 4 times the WLL per jack.
Could be used this statement in order to certify the whole assembly? (trailer with jacks)

Many thanks in advance

For Machinery Directive you should perform a risk assessment, typically using EN 12100:2010 and perform assessment against Annex I, which it sounds like you have started.
I would go back the manufacturer of the jack and ask them - if they're not prepared to give you the information you asked for, you might want to consider how much confidence you can place in the performance data specified in datasheets.

Another option to consider, would be to use the existing jacks to raise/lower but use additional supports of known performance.

You should also review operating and maintenance manuals for the trailer.

I asked the manufacturers for the CE certification.
As the jacks are commonly used on trailers or semi-trailers, for which the CE Directive is not applicable, the Jakcs are not CE Certified.
Manufacturers are well responsive and they could facilitate to me the documents i could require.
Do you know which are the most significant documents to be used for a certification?

Many thanks
