Scanner systems
First Claim
1. A crane comprising support means comprising a frame arranged to support a load and to move the load along a path, and a scanner system attached to said frame, wherein the scanner system comprises a substantially enclosed housing having a gap in said housing and defining a scanning volume, a radiation source arranged in a corner of said housing and arranged to irradiate the scanning volume with a fan beam of radiation, and radiation detection means, comprising detectors, arranged to detect said radiation passing through the scanning volume, wherein the path is arranged to pass through the gap and into the scanning volume so that the radiation source can scan the load as it moves along the path and wherein the gap is in an upper side of the housing, and a part of the housing supporting at least one of the detectors extends upward adjacent to the gap so as to capture radiation from the radiation source that passes through the gap.
