Freestanding Support Towers
From Garaventapedia
Suitable for solid concrete stairs, steel pan stairs filled with concrete, 76mm (3") thick wood stairs/landings.
Free Standing Support Towers are required when there are no existing walls, non-structural support walls or when the lift is required to be freestanding.
Note:
- For concrete-filled steel pan treads, the towers are either bolted through the treads (where access is possible) or attached to a steel stringer for additional support.
