Brief: To ensure the safety requirements and international interchangeability of standard and non-standard mechanical coupling devices and components, ECE R55 rules the requirements for the devices and which are used for vehicles in categories M, N and O, R147 specifies the requirements for the devices used for in categories T, R or S (agricultural and forestry vehicles) and R102 applies for closely coupled devices (CCD).
|R55||R55 applies to the mechanical coupling devices and components devices and components listed below used for motor vehicles and trailers intended to form a ‘Combination of Vehicles’ or ‘Articulated Vehicles’:Class A Coupling balls and towing bracketsClass C Clevis type drawbar couplingClass E Non-standard drawbarsClass F Non-standard draw beamsClass G Fifth wheel couplingsClass H Fifth wheel coupling pinsClass J Non-standard mounting platesClass K Standard hook type couplingsClass L Standard toroidal drawbar eyes for use with appropriate Class KClass S Other coupling devicesClass T Dedicated drawbar type couplingsClass W Non-standard miscellaneous, automatic drawbar coupling clevis type|
Vehicles with regard to the fitting of a mechanical coupling device or component pursuant to Regulation No. 55
|R102||Close-coupling device (CCD)||Vehicles of category |
|R147||R147 applies to the mechanical coupling devices and components used for vehicles of category T, R or S (agricultural vehicles) intended to form a ‘Combination of Vehicles’：Class a80 Coupling ball 80 and keeper plateClass b80 Coupling head 80Class c40 Clevis-type drawbar couplings Class d40-1 Drawbar eyes 40 (nominal thickness:30,5 mm)connecting to clevis-type couplingsClass d40-2 Drawbar eyes 40 (nominal thickness:42 mm)connecting to clevis-type couplingsClass d50 Toroidal drawbar eye 50 connecting to a hitch hook (class g) or a piton-type coupling (class h)Class e Non-standard drawbarsClass f Non-standard towing framesClass h Piton-type couplings with a keeper plate Class i Tractor drawbar couplingsClass j Drawbar eyes which connect to a tractor drawbar (class i) Class q Clevis-type drawbar couplings non-swivel around longitudinal axisClass r Drawbar eye connection with non-swivel clevis type couplings (class q)Class s Other coupling devices and components ||Agricultural vehicles with regard to the fitting of a mechanical coupling device or component|
Note: Some non-standard coupling devices are the combination of various components, for example, the R55 certificate for Calss S-other coupling devices and the R55 certificate for Class D50-Drawbar eyes are both required for one specific manual coupling. And the requirements of some national standards shall be taken into consideration.
R55: Dynamic Durability Test, Static Test (if any)
R147: Dynamic Durability Test, Static Test (if any)
R102: CCD Recovery Distance Test, Stability of the Combination Test, Circular Movement Test, Slopes Inspection
