For normal wind conditions, it is advisable to limit the height of the tower to 3.5 times the smallest dimension of the base (2 levels with 1.00 m frames and 4 levels for 1.50 m frames) For strong wind conditions, the towers should not be isolated but should be connected together or anchored to stabilise them in all directions. T he maximum load is 6 tonnes per standard for towers less than 6 m high. Specific calculations for strength and stability need to be made for higher towers. > Dimensions: Standard Touréchaf with 2 way adjustable heads and screw jacks 100 100 (237 to 346) 15 min to 64 max. 22 min to 82 max. 28 min.to 48,5 max. 22 min to 82 max. 24.3 100 146.3 min to 206.3 max. 28 min. to 48.5 max. 24.3 52,3 à 72,8 100 With one frame: Height from 1.82 m to 2.46 m.
