Designed to take full advantage of the entire S series truss, the ST tower stands out by its flexibility. Sleeveblocks are available for all the trusses from the S range (or combinations). This makes it possible to fit any of the S-series trusses to all four sides, by means of bolted female CCS7 couplers. To achieve the physical quality needed for this tower only the strongest materials are used. The ST sleeveblock is an almost fully bolted structural element, making it much stronger and more precise than conventional welded versions. A S40T truss is being used as vertical mast-section, these mast sections have a one sided horizontal bracing to facilitate safe and easy climbing of the towers. The ST tower is both cost effective and user friendly.
