ABSTRACT:
A base support installation for structures such as runway approach light towers to support the latter normally in a vertical orientation while permitting pivotal movement about a horizontal axis at or near the base to provide ground-level access to the upper end thereof. The support installation includes a concrete slab, a pair of brackets anchored to the slab, and a unitary, Y-shaped member pivotally attached at the extremities of two of its arms to the anchored brackets along a common axis. Mounting means for each of the three legs of the tower, or other supported structure, are provided at equally spaced positions on the three arms of the Y-shaped member. No potentially damaging or misaligning stresses are placed on the supported structure as it is moved about the pivotal mounting of the Y-shaped member and remains attached thereto to all three points.
