Abstract: A rectangular base mounted on wheels and coupled to a tractor. Protection walls preferably made of a steel grid are mounted at the front and rear ends and along the left longitudinal side, the opposite side remaining free from protection wall. A vertical support is disposed parallel to the protection wall mounted on the left side of the base. On the right side of the base there is a non-slip member and an attachment is provided to fix the load of the car frame to the base for transportation. Transverse members are mounted on the base which facilitate loading and unloading of car frames with a fork type loader through the right side wherein no protection wall has been provided.

Abstract: An X-ray volume analysis method of crystalline defects of a part (11), comprises the steps of positioning the part in the plane situated at equal distance from the focus of an X-ray source and a focusing plane (14); illuminating the part from a punctual X-ray source (10) by a beam of a large spectral width .DELTA..lambda. and of determined angular opening .DELTA..theta., the opening .DELTA..theta. of the beam being fixed by .DELTA..theta..ltoreq..DELTA..lambda./2d.cos.theta., d being the interreticular distance for the considered reticular planes; orienting the part (11) to obtain the diffraction on a chosen family of reticular planes (30); and collecting and analyzing the X-ray beam near the focusing plane or beyond.
