MULTICETA® SYSTEM

>2 This is an informative catalogue about CETA products for the Italian and the European markets. For a proper use of CETA equipment, we recommend to observe the specifications quoted both in the Ministerial Authorization books and in the calculation reports signed by a qualified engineer. The use of either supporting scaffolds or staircase towers as well as all improper use not mentioned in the Ministerial Authorization books is prescriptive according to the regulations in force. For the use of both supporting scaffolds and staircase towers, calculation reports duly signed by a qualified engineer...

- COMPANY PROFILE - CETA was established in 1947 in Bergamo, that is that region of northern Italy which is considered as the cradle of the Italian building tradition. It has been producing scaffolding systems and accessories for the construction field since then and thanks to the long experience acquired over the years, together with the new technologies and patents developed, it has achieved a top-quality level both in the construction and in the sport and entertainment sectors. As a matter of fact, the wide range of products offered by CETA includes different types of scaffolds and components...

- Automated production Most production in CETA is automated. When ready, our products are directly delivered to the building site or stocked by our distributors.

- MULTICETA® SYSTEM OLD AND NEW ADVANTAGES Multiceta is the result of the improvement of both the traditional tube and coupler scaffold and the prefabricated frame, of which it keeps the best qualities. Yet, modern multidirectional scaffolds are characterized by a modularity and a versatility that traditional scaffolding systems don’t have. In addition to these features, Multiceta offers more safety guarantees and building flexibility. Thanks to its 8-connection rosette welded to the standard - which allows to connect up to 8 elements through the insertion of the wedges in the holes – Multiceta...

The solidity of Multiceta is guaranteed by the quality of the steel used as well as by the thickness of its components. The rosette, the wedges and the ledgers are all in steel S355JR, which is highly resistant. Thanks to the rational connection system of the components, Multiceta can be assembled very fast. The absence of bolts permits the erection of a robust and flexible scaffold with just a simple hammer blow. The weight is well-balanced on the standards through the rosette, so the structure becomes extremely rigid

- MC Loading platforms Multiceta loading platforms are recommended every once it is necessary to create a loading area adjacent to the façade scaffold. Yet, they are mainly used in order to avoid the erection of “castle” loading platforms starting from the ground, which are definitely more expensive, cumbersome, slow and difficult to assemble. As you can see in the picture, the outward overhang of such platforms is 1.80 m, while their length is strictly related to the pace of the façade scaffold, which is usually 1.80 or 2.50 m. Of course, multiples of these paces are also available (i.e. 1.80...

- Applications Site requirements: Construction scaffolding – height 70 m; inner decks, loading platforms and protection brackets Height 70 m Without standard doubling With loading platform

- DECKS FOR MULTICETA® SYSTEM -CK series Safe assembly The deck head is pressure-inserted and fixed with 8 TOX® joints. This special manufacture allows a well-balanced weight distribution on the deck without stressing the fixed joints, thus preventing the deck head from detaching during loading. Clinching The sheet steel is folded in order to remove all welded joints. This procedure makes the deck rigid and indestructible. High resistance All elements, from the special profiling to the reinforced shoulder, give high resistance and stability to the deck. In some applications, such as the construction...

- TMC lattice girders - Wide span structures Multiceta and TMC structures can be combined together to build catwalks and protection roofs for both the construction and the sport & entertainment sectors. The TMC system is very easy to assemble and offers a range of applications that once needed a tremendous number of tubes and couplers to be carried out.

- TMC lattice girders Site requirements: Renovation of an attic and construction of lofts. Solution: maintenance scaffolding and protection roof with a 17.90 m span width. Engineering and designing: CETA Engineering Department - Bergamo Company responsible for the assembly: Società di montaggi Tarantino

Solution: A structure composed of supporting towers 1.50 x 1.80 m with warp 2.30 x 2.70 Engineering and designing: CETA Engineering Dept. - Bergamo Supervision of construction: CETA - Bergamo Company responsible for the assembly: Società di montaggi Tarantino > Milan – Festa dell’Unità (PDS-party national meeti

Night-work is never easy, but this building site was even more complex than usual, because the by-pass had to be closed for 5 hours and the 45 m-bridge had to be assembled in record time. These few pictures will give you an idea of the difficulty of the assembly operations < Positioning of the central support of the structure
