Stair/Elevator Tower


Built to match precasters' requirements:

  • Form provides the ability to cast a single piece box for stairs or elevator shaft.
  • Can be built to adjust to several lengths and widths. Customer can determine the minimum length and width and the size(s) it needs to expand to.
  • The wall thickness is normally fixed, but can be adjusted by moving the sidewalls and changing the soffit.
  • Can be built with an option for an integrally cast landing.

Outer form rolls back, inner core is hydraulically collapsible. Custom made top ties and under ties hold the form firmly in place. Vibrators and vibrator brackets can be built onto the outer form. A catwalk can be built for access to the form.
