During the assembly stage of Modular Cup-Lock Scaffolding System the vertical and horizontal components are rigidly connected to each other with the strokes of a hammer. As the vertical and horizontal components make up a rigid frame there will be no issues of stability and no need for diagonal elements. Modular Cup-Lock Scaffolding System, with its strong and rigid structure can be used as a cast scaffold to haul heavy loads as well as being used as a work scaffold on the facades. In a case as such if the intervals between the vertical components are too wide, rigidity can be established with the diagonal elements.

The locking device is formed by a fixed lower cup, which is welded to the vertical at 0.5 m intervals, and a sliding upper cup. The forged blade ends of the horizontals are located in the lower cup. The upper cup is moved down and rotated by hammer blows to give a positive and rigid connection. The component headpieces that are connected to the cup-locks on the vertical components can rotate around the vertical axis. The horizontal components that are connected at different axis make possible for practical assembly of the scaffolding at different geometrical shapes.

The cup-lock connections that are placed at 500 mm intervals on the vertical components increase the load capacity of the scaffold.
The horizontal components are placed at intervals of 500 mm or in its multiples based on the static calculations.
