X-ray device for checking the contents of closed cargo carriers
First Claim
1. A device for checking the contents of closed cargo carriers using x-rays comprising:
- two steerable single track carriages disposed parallel to each other;
a plurality of vertical columns having a bottom end and a top end wherein said bottom end is supported by said carriages;
a yoke having a right end and a left end connected to said top end of each vertical column so as to space apart said carriages, said yoke being vertically movable on said columns;
a first series of supporting elements connected to said right end and said left end of said yoke;
a cross beam having a first end and a second end disposed on said yoke and spanning between said carriages;
a first and a second support respectively connected to said first end and said second end on said cross beam;
an x-ray radiation source disposed on one side of said cross beam and connected to said first support; and
a receiving screen located on the opposite side of said cross beam so that when said device travels along the cargo carriers, it x-rays the contents of these carriers.

Abstract
An x-ray examination device for checking the contents of closed cargo carriers having two steerable single-track carriages disposed parallel to each other, wherein the carriages each support a vertical column. The free ends of the columns are connected to each other by means of a yoke spanning the space between the carriages, which corresponds to the maximal possible width of the cargo containers. The yoke can be raised and lowered on the two columns. Cantilevers are aligned horizontally, and parallel relative to each other, and are arranged on the yoke. The free ends of the cantilevers support a cross bar. Connected to one end of the cross bar are supports for supporting the x-ray equipment. The x-ray equipment includes an x-ray emitter and an x-ray receiver. Moreover, one or more screen vehicles having leaded mesh screens for surrounding the cargo containers are provided to shield against harmful x-rays outside the cargo container area.
