Tower elevating assembly

A tower elevating assembly, comprising:

• (a) a platform assembly configured to move between a first elevation position and a second elevation position, the platform assembly having a first and second ends and a platform therebetween, the platform having a longitudinal axis;
• (b) a single stage tower supporting the platform assembly, the single stage tower located near the first end of the platform assembly and spaced from the second end of the platform assembly, the tower having a first end and a second end and including a track assembly, wherein the track assembly includes first and second track portions extending between the first and second ends of the tower, wherein each of the first and second track portions includes at least first and second adjacent channels, wherein each of the first and second track portions is manufactured as a single continuous extruded structure made from extruded aluminum, and wherein a portion of the single continuous structure of each of the first and second track portions defines the at least first and second adjacent channels of the respective first and second track portions, wherein the first and second track portions are arranged such that openings to both of the at least first and second channels of the first track portion face openings to both of the at least first and second channels of the second track portion, wherein the tower further includes a leg assembly extending from a base of the tower, and wherein the tower is configured to be anchored to a ground surface by base attachments points located on the leg assembly;
• and
• (c) a carriage assembly for providing support to the platform assembly, the carriage assembly having a first end adjacent the tower for supporting the first end of the platform assembly and a second end spaced from the tower for supporting the second end of the platform assembly, and the carriage assembly including a tower interface at the first end of the carriage assembly configured for moving first and second rollers within the first channels of the first and second track portions, wherein the first and second rollers are configured to rotate about an axis parallel to the longitudinal axis of the platform, wherein the platform assembly is configured to move along the track assembly between the first elevation position at the first end of the tower to the second elevation position at the second end of the tower, wherein a vertical reach of the platform assembly is limited to a length of the single continuous extruded aluminum first and second track portions.
