Patent ID: 7716820

Claim:
Apparatus for deploy-attaching beam-mount structure to the outside of an elongate column at plural, defined attachment sites that are distributed and spaced along the length of the column comprising a frame, column support structure mounted on said frame and designed to support, releasably, an elongate column with that column's long axis disposed generally horizontally, and a carriage mountable for translation on and along a column supported by said column support structure, with the column acting as a travel way for said carriage, and with said column support structure being designed to accommodate shifting of the carriage progressively along the length of a supported column, said carriage including deploy-attachment staging structure adapted to support/transport releasable beam-mount structure for deploy-attachment to such defined attachment sites on a column supported by said support structure, wherein said column support structure takes the form of a plurality of spaced and distributed support yokes having openable/closeable swing arms which are closeable to circumsurround the long axis of an elongate column supported on said support structure, and which further includes circular-perimeter guide rings which are releasably attachable to the outside of a supported column each in a manner circumsurrounding the long axis of the column, and said arms carry idler rollers adapted, with closing of the arms around a column, to engage and capture the circular perimeters of said guide rings, thus to permit selectable rotation of a guide-ring-supported column within the yoke and about the long axis of the supported column.
