  • Patent number: 8151934
    Abstract: A portable observation tower and system of raising and lowering the tower is disclosed. The tower has a tower box with two fixed sectioned front legs and two hinged sectioned back legs. To raise the tower front legs are pulled toward back legs with a winch system mounted on a trailer hitch system. Rolling landing gear is lowered and drawn by winch to a front most locking position. This raises the mid section of tower box reducing the angle of front legs to back legs. Once complete the winch line can be attached to an axle of back legs to draw back legs to front legs. This process elevates tower to its full upright position. Wheels are provided on back legs and on trailer hitch system for movement of the tower. The lowering process occurs in reverse order of the raising process.
