Cup-lock Type Scaffolding is a system used as both high load carrier and face scaffolding. This is a scaffolding system having high endurance and safety values used in heavy laying and taller building constructions.


 The system is comprised of upper and lower cup props and interconnection of forged headed horizontal components that prevent twisting of props. Cup props, which construct the system, are manufactured from 48x3 mm TSE Certificated industrial pipes of 50, 100, 150, 200, 250 and 300 cm in length at 100 cm cup intervals (50 cm according to load) as a standard.

The forged headed horizontal connections are manufactured from 48x2.5 mm TSE Certificated industrial pipes of 70, 100,120, 150, 200, 250, 300 cm in length as a standard. The cup connections on vertical props at 50 and 100 cm intervals prevent the twisting of scaffolding props and increase the load capacity.

Installation is started by using the lower adjustment shafts. Preliminary feet are placed on the lower adjustment shafts. After preliminary feet are connected with horizontal components, the vertical components are placed on them. There are cups and covers at 50 cm or 100 cm intervals on vertical components. The cups are made of 5 mm sheet and welded to the props.

 There are movable covers on these cups that are manufactured as nodular cast iron and that enable horizontal components locked. The system is set by interconnecting the vertical components with horizontal components.

There are forged heads on both tips of the horizontal components. The horizontal components are fit into the cups, the covers are closed and locking is fulfilled by hammering. Finally, the installation is completed by placing upper adjustment shaft over the vertical components. Since the vertical and horizontal components construct a rigid frame, there is no need for diagonal connection. A twisting secured and safe installation of scaffolding with high load capacity is ensured since the vertical and horizontal components construct a rigid frame. For instance, when a prop having 50 cm cup intervals is connected with horizontal components on both sides, it is able to carry more than 6 tons of axial loads. The capacity of a prop having a 100 cm cup interval is 5 tons of loads. .

For Cup-lock type scaffolding systems, the axial spaces are fixed depending on the capacities of the main carriers (ridge) and the auxiliary carriers (grid) and on type of formwork as in the other carrier systems.

The parts are painted by dipping method in order to be resistant against wear out and deterioration. They are optionally galvanized as well. 
Special production is available apart from standard production.  

Each prop has a 6 ton load capacity (in case of connected with horizontal components on both sides).
This load capacity is varying depending on different scaffolding heights.

This is lighter than the other scaffolding system in its class. All mounting and carrying process is carried out by hand.

Its stability against twisting force is considerably high due to its vertical and horizontal connection method.

The installation of scaffolding is performed swiftly and easily by only two materials (vertical and horizontal components) without needing any other equipment except a hammer.
