ABSTRACT:
A portable, adjustable structure for supporting an equipment unit at a distance above a support surface has a lower tower structural member placed on the support surface. Pivot support structural members are affixed to the lower tower structural member in a manner whereby the pivot support structural members are upright relative to the support surface. A plurality of struts are utilized to stabilize the lower tower structural member and the pivot support structural members on the support surface. A tower member is pivotally mounted on the pivot support structural members. The tower member has spaced opposite first and second ends. The equipment unit is affixed to the tower member at the first end thereof. The tower member is pivotally movable to a position substantially perpendicular to the support surface with the first end thereof spaced farther from the support surface than the second end thereof. Ballast is affixed to the tower member at the second end thereof. The second end of the tower member is coupled to the lower tower structural member whereby the tower member is normally upright and is pivotable, upon uncoupling of the tower member and the lower tower structural member, to position the equipment unit close to the support surface for maintenance and repair.
