The basic 30cm (11,42in) Tower for ground supported HD/FD44, HD/FD34, XD and Roofs
The Basic Tower
The ground support tower HD/FD34 makes for an excellent vertical truss that allows the safe, quick lifting of regularly loaded horizontal truss con- structions (riggs) and small to medium-sized platform roofs to their service height.
The straight elements of the tower consist of HD/FD34 Standard Truss, allowing a variety of combinations.
This system is compatible with the type HD / FD34 Basement (Touring & ProBase in aluminium and a steel base with long and short outriggers), Hinge Section, Sleeveblock and Top Section.
In terms of statics, ground support towers, indoor applications, are exposed to negligible flexural strain but primarily to pressure strain.
In outdoor use, on the other hand, the tower is exposed to very high flexural strain due to the coverings or roof.
