Usually, each of the two undercarriages is equipped with a pair of support spouts, which are supported at their ends applied by the heavy-duty body in the center of the undercarriage on the main connection beam by means of a ball socket. This is generally done with the interposition of a guide point support, by means of which - in a manner not to be explained here - the pivot point of the support jaws for cornering from the center of the

Because of the induced thereby great weight such bolts are difficult to handle, and it is difficult, such a heavy bolt in the three successive bores of Ansehlußla- see insert, two of which ψ to the heavy sitting body, and between the third, Include connector tab seated on carrying spout. Since these three bores have the same diameter in the previous version of the Tragschnabel car, the bolt must be pushed through these bores one after the other over its entire length of 300 to 400 mm. This would require an unacceptable expenditure of force if the cylindrical bolt were not guided in the bores with a certain amount of play. Such play in such a highly stressed socket pin coupling is, however, impermissible, since
