3 Level Screens
Screens can come in varying heights to suit different on-site conditions. A 3 Level Screen is one whose height is large enough that it can protect three levels of the structure plus a handrail height of at least one meter on the highest level, as depicted by the sketch below.
A 3 Level Screen is the smallest Screen that can be climbed hydraulically and that can be used as a viable option for medium to high rise construction. The 3 Level Screen can house a typical tower formwork cycle and is usually used in structure only scenarios.
