Item 25 (Articulation angles as installed) (R55-02-05; R55-05-13; R55_07_10; R55_09_21; R55_12_06; R55_12_07; R55_13_09; R55_13_10; R55_13_17; R55_13_19¸ R55_13_20; R55_13_21; R55_13_29; R55_13_30)
Mr. Stokreef had elaborated the proposal from our January meeting R55_13_09 and R55_13_10. This proposal was discussed. The change annex 7 proposed for a drawbar coupling was agreed. The change to annex 7 for fifth wheel coupling was not agreed. For fifth wheel couplings Mr. Alguëra during the meeting worked out a proposal to make a change to annex 5. Mr. Svensson had got comments from one OEM that 3,5° towards the front and 4,5° towards the rear would be what can be achieved on a general base as installed on a vehicle. The general opinion at the meeting was that in annex 5 the focus is on the component and not the installation. The large variability in the installation and combination with different trailers has to be accounted for by the OEM. It is believed that interference between trailer and tractor will cause damage but not result in lost trailers. The proposal from Mr. Alguëra was summarized in document R55_13_30. This was agreed. [In retrospect the secretary found the R55_13_30 not to be unambiguous. Hence he has challenged the experts with a reformulated proposal. This is done through a separate mail.]
