An equipment tower having a ladder formed of a plurality of ladder segments each joined to a respective tower segment by a pivotal connection prior to the tower segments being stacked during erection of the tower. The pivotal connection provides a degree of freedom of movement which facilitates the interconnection of adjoining ends of the ladder segments after stacking of the tower segments. Additional accommodation of as-built spacing of the adjacent ends of the ladder segments may be provided by a connecting segment. The pivotal connection may be a rod inserted through a rung of the ladder and supported by a support assembly attached to the tower segment.
