ABSTRACT:
An elevator apparatus for providing an elevated support structure. The apparatus is comprised of a base unit, a plurality of tower sections, and an elevating device. The tower sections may be individually inserted into the base unit where the elevating device operates to raise the base unit whereby an additional tower section may be inserted and connected to the previous tower section. The elevating device is then lowered to the just inserted tower section and repetition of the sequence affects an erection of the tower. Outrigger legs with pads extend from the base unit to provide vertical stability. Guy lines extend from the tower to the ends of the outrigger legs to a winch arrangement within the base unit permitting guy lines to remain taught during the raising or lowering of the tower. Further, ballast containers are provided at the base unit intermediate adjacent outrigger legs for providing additional stability against tip-over.
