Since KD 100 System is stable as free standing, high load bearing capacities are possible by varying the distances between the towers. The system is very simple and quick to assemble, put the jack screws under the frame and just start stacking the "H" items on top of each other, without any snap locks or cotter pins. System diagonals are available for extra rigidity, especially when the towers are prone to lateral loads such as high wind loads etc. System can easily be fixed together for crane handling by the diagonals and jack screw holders.
