The ground support tower FD34 makes for an excellent vertical truss that allows the safe, quick lifting regularly loaded horizontal truss constructions (riggs) and small to medium-sized platform roofs to their service height. The straight elements of the tower consist of FD34 Standard Truss, allowing a variety of combinations. This system is compatible with the type FD34 Basement (Touring, Professional and Small Base), Hinge Section, Sleeveblock and the Top Section. Depending on the area of application, several different sleeveblocks are available making it possible to incorporate several different systems. Two different top sections are supplied for manual or electrical chain hoist. Three different designed basements guarantee optimum stability. In terms of statics, ground support towers, in 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. |
