Boom with mast assembly
First Claim
1. A mobile transport for scanning targets with penetrating radiation, for movement relative to the targets along a direction of travel, comprising:
- a) a chassis;
b) a source of penetrating radiation mounted to said chassis;
c) one or more receptors for said penetrating radiation;
d) an instrument boom, said instrument boom comprising a mast assembly and a first boom section having longitudinal and transverse dimensions, said first boom section comprising;
a longitudinal member comprising an external surface;
a plurality of longitudinal sections, each section comprising two ends;
one or more substantially transverse flanges having opposing faces,said flanges defining at least one hole from one face to the other; and
a plurality of longitudinal beams;
wherein said longitudinal member is internal to said longitudinal sections, at least one end of each section is joined to the face of one or more flanges, the longitudinal member extends through the hole in the one or more flanges, the external surface is joined to said one or more flanges, and said longitudinal beams rejoined to the flanges; and
e) wherein said first boom section is supported by said mast assembly, and said one or more receptors are mounted to said instrument boom.

Abstract
A torsion- and bending resistant boom formed of beams running the length of the structure, a set of pierced, transverse flanges arrayed along, and substantially perpendicular to, the length of the structure, a continuous longitudinal member running the length of the structure, piercing the flanges, and several further longitudinal members, outward of the first member. The longitudinal members are welded to the flanges. An elevatable mast assembly raises and lowers the boom, and has a mast and guides formed of hollow tubes, and rollers between the guides and the mast, the rollers transferring torque loading to the guides.
