Stair/Elevator Towers and Vaults are built to match precasters’ requirements. Tower forms are designed to cast a single-piece box for stairs or an elevator shaft. Your product requirements determine minimum and maximum lengths, widths and sizes to which they need to expand. Wall thicknesses are adjustable by moving side walls and changing soffits. Inner cores are hydraulically collapsible, and outer forms roll back on tracks.
Vault/box forms are like tower forms with some differences. Vaults will have a fixed core to create a five-sided structure. Cores can have multiple chambers, slopes and depths. Side forms can be rolled away, lifted away or hydraulically opened to lay flat.
