Patent ID: 7246782

Claim:
A portable base for supporting structures that extend vertical distances of at least twenty feet comprising: a framework adapted for separation and separate transport from a structure it is adapted to support; the framework comprising a plurality of structural members formed into a box-frame capable of supporting at least 1000 pounds, the box-frame including a bottom and a top and a center axis through the bottom and top; the framework including a connection to which a structure is removably attachable at or near the top; and the bottom and top defining a space therebetween into which can be placed one or more removable devices; a power generator removably positioned in the space; four outriggers telescopically extendible from the base outwardly, each of the outriggers independently extendable along different substantially radial directions from the center axis, each outrigger comprises an arm having a proximal end and a distal end, the proximal end connected to the framework, the arm being expandable over a range of positions between a first position where the distal end of the arm is nearest the framework and a substantial portion of the telescopically extendible arm is towards the center axis within the framework, and a second position where the distal end of the arm is farthest from the framework, so that resistance to overturning moment can be variably adjusted by variable addition of weight to the frame and variable adjustment of position of each outrigger.
