The FF20 Shoring Tower is a load bearing tower that consist of only 5 different standard components with base dimensions of 1.00m x 1.00m. Since the Head and Base Jack’s combined adjustment range exceeds 33cm grid of the frames, any tower height can be erected. All individual components are hot-dip galvanized. The dead load of a FF20 shoring tower comes up to 42 kg/rising meter which include Head and Base Jacks. In order to allow adaptations to inclined surface of up to 6%, the bearing plates of the Head and Base Jacks are fixed. The total adjustment range of the Head and Base Jacks is almost 60 cm. Both vertical frames 100 and 133 require only one type of FF20 Diagonal as bracing. Owing to the required assembly procedure, the same rigidity in all vertical planes of the tower is achieved by changing the position of frames by 90° from lift to lift. All vertical and end frames are connected by the built-in quick fastening connectors. The post of the vertical frames consists of 48.3mm dia. tube which allows mounting of bracing by common scaffold tubes with a Rigid or Swivel Coupler 48/48. The towers may have to be stabilized by horizontal anchoring at certain levels depending on the total tower height. Details of the vertical distances for this type of stabilizing method can be taken from the relevant load tables.
The FF20 Formwork System is designed and manufactured in accordance with BS EN 12812 : 2008, code of practice for Falsework
