ISO 4009:2000 pdf free download.Commercial vehicles — Location of electrical and pneumatic connections between towing vehicles and trailers.
There were a number of reasons for this revision.
Both transport-industry trade unions and operators had been critical of the arrangement of the electrical and pneumatic connections on the rear cross-members of towing-vehicle chassis according to Iso 4009:1989. reporting an incidence of hand injuries and damage to supply lines and coupling heads.
Until now, no standard specified the arrangement of electrical connections on semi-trailers (ISO 1728, for example, relates only to pneumatic connections), nor of electrical and pneumatic connections for close-coupled vehicles.
It had become necessary to revise requirements of ISO 1728 in order to obviate the deleterious effects that walkways on the tractor have had on flexible connecting lines.
ISO 4009 now covers the use of 15-pin electrical plug connectors and the quick pneumatic coupling.
ISO 4009 specifies the locations of coupling devices for electrical and pneumatic connections between towing and towed commercial road vehicles. It is applicable to heavy vehicles equipped with pneumatic braking systems and 24 V electrical equipment of the following types: drawbar-trailer combinations whose towing vehicles have rear-mounted couplings or couplings mounted forward and below, and articulated vehicles.

Within the shaded area, connections should be located as far outwards as possible. For ergonomic reasons, the connections should be able to be operated while standing on one side only of the drawbar. As alternatives to mounting the connections left and right of the vehicle’s longitudinal axis, they may be mounted on the left side only of the reference plane for left-hand drive vehicles, or on the right side only for right-hand drive vehicles.
NOTE Type B is a necessary alternative to type A (Figure 1) for the case where there is an addtionaJ installation according to type C (Figure 3).

m3.2 Connection dimensions
The types and dimensions of electrical and pneumatic connections should be in accordance with ISO 1185,
ISO 1728, ISO 3731, ISO 7638-1 and ISO 12098.
3.3 Clearance space
The clearance dimensions to be provided around the connections to ensure safe handling shall be in accordance with Figures 5 and 6. If non-standardized connections are used, the specified clearance space shall address the safety considerations referred to in the introduction.
3.4 FlexIble pipe connection
3.4.1 LocatIons
The flexible pipe connections (with coupling head at the end of the pipe) shell be integrated components at:
— the trailer, in the case of a drawbar-trailer comb.naIion
— the tractor. n the case of an articulated vehicle,
3.4.2 Length
3.4.2.1 Towing vehicles with rear-mounted coupling
In the case 04 these drawbar-trailor combinations, the location and length of the pipes depends on the location of the coupling heads and the fact that the maxiniLan angle between the drawbar centre hne and the longitudinal axis of the towing vehicle ts 75’ (see lSOl 1406)
For angles of less than 60’, there shall be complete freedom of lateral movement, without tension on the pipes, and without the pipes ritbing against one another: for angles 01 from 6O 10 75’, lateral movement shall be possible without causing detenoration 04 the pipes,
3.4.2.2 Towing vehicles with coupling mounted forward and below and articulated vehicles
In the case CA these drawbar-trailer combinations and for that of articulated vehicles, the location and length of pipes depends on Ihe location 04 the coupling heads and the lact that the maximmi angle of articulation Is 90 (see ISO 1726 and ISO 11407).
For angles within this range, lateral movement shall be possle without causwig del erioration of the pipes The nigement area on the Racier may be aimed 9Cr max. t4 from Ste hodzontai.
