3. INSTALLATION
(See Fig. 1)
Important note:
The pertinent regulations (e.g. Accident Prevention Regulations for Vehicles) and the attachment guidelines
of the vehicle manufacturers must be observed when installing the coupling!
Attachment of the coupling:
Official national regulations must be observed. For example: in Germany the obligations §13 FZV regarding
the data in the car license concerning the permissible trailer weight as well as the permissible vertical load
must be considered.
Installation:
• Push slider from above into the slots of the guide rails of the coupling frame.
• Shift locking pins right and left into the slider by use of the handle.
• Move to the preferred height position, release handle and engage automatically into the
appropriate holes of the coupling frame.
• In general it is to be checked after each adjustment of the slider whether the locking pins are properly
engaged in the holes of the guide rails. Only then the correct locking state is given.
• The guide of the slider (120 mm long) must not project beyond the guide slots of the frame, both above
and down.
4. DESCRIPTION AND OPERATION:
The pertinent safety regulations must be observed when coupling and uncoupling.
No one may stand between the vehicles. The coupling may only be operated in locked condition.
When coupling and uncoupling, the drawbar must be as horizontal as possible relative to the coupling. For a
37 mm pin, the maximum possible inclination of the drawbar in the axial direction when coupling or uncou-
pling is 10°. A 32 mm pin can be coupled or uncoupled at a maximum possible inclination of 20°.
4.1 Description:
The coupling is an automatic trailer coupling, its clevis dimensions and field of application complying with
DIN 11028 or ISO 6489-2 and RREG 2009/144/EC. Its design incorporates the lever trigger system, i.e. the
coupling procedure is triggered by moving a trailer ring into the clevis and pressing back the trigger lever. In
its normal state, the device is in coupled and locked position.
The automatic trailer coupling can be pivoted through 360°, the torque required for this purpose being 0.1 -
0.15 kNm. Appropriate remote controls may be used.
4.2 Operation:
4.2.1 Uncoupling and opening the coupling:
Use supporting jacks or similar to stop the trailer rolling away. Push up the hand lever until it engages. This
releases the locked position and presses outwards the two locking/safety pins located on either side, as
