PART D Vehicles of category O

1. Maximum authorised dimensions

1.1. The dimensions shall not exceed the following values:

1.1.1.

Length

(a)

Trailer: 12,00 m including drawbar;

(b)

Semi-trailer: 12,00 m plus the front overhang.

1.1.2.

Width

(a)

2,55 m for any vehicle;

(b)

2,60 m for vehicles fitted with a bodywork with insulated walls of at least 45 mm thick, as referred to in Appendix 2 to Annex II to Directive 2007/46/EC.

1.1.3.

Height: 4,00 m.

1.1.4.

Front fitting radius of semi-trailer: 2,04 m.

1.2. For the purposes of measurement of the length, width and height, the vehicle shall be at its mass in running order, placed on a horizontal and flat surface with tyres inflated at the pressure recommended by the manufacturer.

1.3. The measurement of the length, height and front fitting radius shall be conducted where the loading surface or the reference surface referred to in point 1.2.1 second subparagraph of Annex 7 to UNECE Regulation No 55 is horizontal.

Adjustable drawbars shall be horizontal and aligned with the centre-line of the vehicle. They shall be set at their horizontal most elongated position.

1.4. Only the devices and equipment referred to in Appendix 1 to this Annex shall not be taken into account for the determination of the dimensions referred to in point 1.1.

2. Mass distribution for vehicles fitted with bodywork

2.1. Calculation procedure

Notations:

‘M’

technically permissible maximum laden mass;

‘m₀’

technically permissible maximum mass at the front coupling point;

‘m_i’

the technically permissible maximum mass on the axle designated ‘i’, where i varies from 1 to the total number of axles of the vehicle;

‘m_c’

technically permissible maximum mass at the rear coupling point;

‘μ_j’

the technically permissible maximum mass on the group of axles designated ‘j’, where j varies from 1 to the total number of groups of axles.

2.1.1. Suitable calculations shall be carried out in order to make sure that the requirements set out in points 2.2 and 2.3 are fulfilled for each technical configuration within the type.

2.1.2. In the case of vehicles fitted with loadable axles, the calculations required under points 2.2 and 2.3 shall be carried out with the suspension of loadable axles in the normal running configuration.

2.1.3. In the case of vehicles fitted with lift axles, the calculations required under points 2.2 and 2.3 shall be carried out with the axles lowered.

2.2. General requirements

2.2.1. The sum of the technically permissible maximum mass at the front coupling point plus the technically permissible maximum mass on the solo axles or group of axles plus the technically permissible maximum mass at the rear coupling point shall be not less than the technically permissible maximum laden mass of the vehicle.

2.2.2. For each group of axles designated ‘j’, the sum of the masses m_i on its axles shall not be less than the mass μ_j.

In addition, each of the masses m_i shall not be less than the part of μ_j applying on the axle ‘i’ as determined by the mass distribution for that group of axles.

2.3. Specific requirements

2.3.1. The mass of the vehicle in running order, plus the mass of the optional equipment plus the technically permissible maximum mass at the coupling point(s) shall not exceed the technically permissible maximum laden mass of the vehicle.

2.3.2. Where the vehicle is laden to its technically permissible maximum laden mass, the mass distributed on a solo axle ‘i’ shall neither exceed the mass m_i on that axle, nor the mass μ_j on the group of axles, nor the technically permissible maximum mass at the coupling point m₀.

2.3.3. The requirements of point 2.3.2 shall be complied with in the following load configurations:

2.3.3.1. Uniform distribution of the pay-mass

The vehicle shall be at its mass in running order plus the mass of the optional equipment plus the pay-mass being distributed uniformly on the cargo area;

2.3.3.2. Non-uniform distribution of the pay-mass

The vehicle shall be at its mass in running order plus the mass of the optional equipment plus the pay-mass located in accordance with the manufacturer’s specifications.

For such purposes the manufacturer shall state the extreme permissible possible positions of the centre of gravity of the pay-mass and/or body and/or equipment or interior fittings (for instance: from 0,50 m to 1,30 m in front of the first rear axle);

2.3.3.3. Combination of uniform and non-uniform distribution:

The requirements of points 2.3.3.1 and 2.3.3.2 shall be fulfilled simultaneously.

2.3.3.4. The requirements of points 2.3.3.1 shall always be fulfilled where the vehicle is fitted with a flat cargo area.

2.3.4. Specific requirements for trailer caravans

2.3.4.1. The minimum pay-mass (PM) shall meet the following requirement:

Where

‘n’

is the maximum number of berths and

‘L’

is the overall length of the body length as defined in point 6.1.2 of Standard ISO 7237:1981.

3. Manoeuvrability requirements

3.1. Trailers and semi-trailers shall be so designed that, when coupled to a towing vehicle, the combination is capable of manoeuvring on either side of a complete trajectory of 360° made up of two concentric circles, the outer circle having a radius of 12,50 m and the inner circle having a radius of 5,30 m without any of the vehicle’s outermost points of the towing vehicle protruding beyond the outer circle or any of the outermost points of the trailer or semi-trailer intruding inside the inner circle.

3.2. A semi-trailer shall be deemed to comply with the requirement of point 3.1. if its reference wheelbase ‘RWB’ meets the following requirement:

where:

‘RWB’

is the distance between the king-pin axis and the centre line of the non-steering axles.

‘W’

is the semi-trailer’s width

3.3. Where one or more of the non-steering axles has an axle lift device the reference wheelbase with the axle lowered or the axle lifted — whichever is the longest — shall be taken into account.
