Boom for material transport

A foldable boom comprising a first boom element in the form of a telescoping extendable boom for transporting an item, said telescoping extendable boom having a plurality of tubular elements, each of said tubular elements being a arranged with a longitudinally extending track inside said tubular element, each said longitudinally extending track supporting a single shuttle internally inside its tubular element for movement therealong, each said shuttle being equipped with a clamp to selectively clamp said item, the longitudinally extending tracks of immediately connecting telescoping tubular elements being located opposite each other, and inner tubular elements inside said telescoping extendable boom being arranged at their near ends to allow their shuttles to access shuttles of outer tubular elements to enable clamps thereof to transfer a said item therebetween;

• said first boom element being connected at one end thereof to a second boom element about a folding axis, said second boom, element also having a longitudinally extending track inside said second boom element supporting a shuttle internally for movement therealong, wherein said foldable boom is configured to allow the shuttle of said second boom and the shuttle in the tubular element at said one end of said first boom element, to transfer a said item therebetween.
