2. Relationship to other equipment:
The B50-X stabilising coupling head is designed to be used on overrun-
braked trailers with towing vehicles using class A coupling balls (ball with
a 50 mm diameter), meeting the requirements of ISO1103 and ECE R55
respectively. The spring-loaded friction element results in damping of any
self-induced oscillating and pitching movements to the trailer, which
results in a higher critical speed of the vehicle-trailer combination whilst
also meeting the requirements of ISO 11555:1.
Accordingly, these stabilising coupling heads have been approved for
vehicle-trailer use with a maximum permissible speed of 100 km/h.
3. Application scope:
The permissible load values of the coupling head – see type plate or technical data
– must be at least equal to those of the trailer.
The stabilising coupling heads may only be used with class A coupling balls (ball
with a diameter of 50 mm according to ISO 1103) of the ECE R55.
The coupling head can be pivoted ±25° laterally and ±20° about the transverse axis
on the ball.
The stabilising coupling heads can only be used with
coupling balls according to DIN 74058 / ISO 1103, if
the ball neck is free of attachments over the range
of 35 mm.
(35 mm instead of 32 mm in DIN 74058 / ISO 1103)
