    Wind Management

    Wind resistence is calculated with 3 side mesh canopies applied to the structure (2 side canopies and one rear canopy). The three roof walls carrying canopies must be secured by guy wire cross bracing at all times with min. loading capacity 1000 kg (2205 lb).

    In service max. windspeed - 15 m/s - 54 km/h - 33 mph

    Out of service max. windspeed - 28 m/s - 101 km/h - 62 mph



    Option 1 - 400 kg / 882 lb ballast underneath each tower base = total of 1600 kg / 3527 lb

    Option 2 - 350 kg / 772 lb ballasts in the 3.5 m (11.5 ft) range from each tower leg attached to the structure by guy wires following the layout in static calculation.
