Draft proposal under development within the R55 informal group.

Chronology summarizing the discussions held on agricultural coupling requirements under UN R55 since 2011.

Proposal to allow for a vertical load up to 80 kg for drawbar coupling designs with a jaw that pivots about the horizontal transverse axis because such configurations are commonly used in fire trucks and other special use vehicles in Germany, Austria and Switzerland.

Proposal as developed by the UN R55 informal group during its 12th session. This proposal concerns a procedure to identify allowable combinations of performance values Dc and V for drawbar coupling equipment. This proposal would amend the Revision 2 proposal for UN R55.
