ABSTRACT:
A mobile tower to be towed from one location of use to another by a vehicle having a rear trailer hitch. The tower has a wheeled base frame mounting a collapsible tower structure and a pivoted hitch tongue which is operatively connected to the tower structure for extension of the tongue into coupling engagement with the vehicle hitch upon lowering of the tower structure to a collapsed towing position and retraction of the tongue from coupling engagement with the hitch upon raising of the tower structure to its erect position of use. The particular tower described is a mobile water tower wherein the wheels raise and lower with the tower structure and the hitch tongue undergoes downward extension movement and upward retraction movement in a manner such that the base frame is lowered into supporting contact with the ground when the tower structure is raised to its position of use and raised to an elevated position wherein the frame is supported above the ground by the wheels and the towing vehicle when the tower structure is collapsed for travel.
