Once again, Moldtech keeps enhancing its capabilities and ensuring its ability to manage different commissioning projects around the world, thus increasing recognition of the brand in international markets.

At present day Moldtech has proudly finished a few successful projects in Spain, in which the different types of installed equipment are working at full capacity.

Among the different type of equipment commissioned are some tilting tables with special upper shutters with hydraulically controlled position adjustment and operated by radiofrequency remote control and an aerial concrete wagon (concrete distributor) with 2m3 capacity that can automatically move from the batching plant to the pouring place.

Besides these projects in Spain, Moldtech is currently managing a few different international commissioning works, in countries like Romania, where our technicians are installing self-reacting prestressing beds 125 m length up to 1300 TN capacity, Sweden where some #tilting tables are being installed, Mexico with a double mould for columns and a MT20 Drycast machine for box culverts, Saudi Arabia where a big factory is being commissioned with 3D moulds for bathroom units and 180º turners, France where some more tilting tables are being installed, and Morocco where a universal casting bed with 70m length and 600Tn capacity is being commissioned.

We would like to thank the opportunities that more and more precast concrete companies are giving us, entrusting Moldtech the manufacturing and commissioning of their precast plants and machinery.

ULMA engineering solutions on the emblematic Arch of Innovation bridge in Brazil

www.ulmaconstruction.com

The arch of innovation is a cable-stayed bridge that will connect Zarur, São João, and Cassiano Ricardo avenues in São Paulo, Brazil. With a height of 100 m, it has become one of the most iconic bridges in the country of its type, given its peculiar arc shape.  This bridge will create a safer and faster route for more than 180,000 vehicles per day, which will ease the city's traffic. It will also include a bicycle lane of more than 3.6 km.

One of the most relevant requirements in this project has been the versatility of the systems and the safety of the operators. To this end, the engineering team developed an integrated solution with the ideal formwork and scaffolding systems and applications for the pylons and the roads that run between them. The Queiroz Galvão construction company has once again trust in ULMA's engineering solutions, as well as in the capacity to respond to a project with stringent execution deadlines.

The ATR self-climbing system was chosen for the two pylons with variable inclination and four-sided section, in combination with the VMK timber-beam formwork for the outside and the KSP platform for the inside. The self-climbing system has been perfectly adapted to the inclination and elliptical curve of the shaft of up to 23º in the last concreting. The whole set has allowed high execution rates, 3-day concreting cycles in 3.6 m high sections, without the need for a crane. In addition, it has three levels of working platforms for carrying out work on the formwork, rebar or concrete, as well as for lifting the structure, thus maintaining strict safety levels at great heights at all times. Despite the complexity of the geometry, the MK system in its different applications has solved all the structural requirements.

The two carriageways rest on an X shape. They were built with ENKOFORM HMK, supported by T-60 shoring towers. A solution of MK gantry formwork was proposed for the rest of the board to avoid closing the tracks.

For the construction of the arch section of the bridge, a supporting structure made of MK and VM beams supported by T-60 shoring systems was constructed. Custom metal profiles bear all the weight of the T-60 shoring system.

To access the different areas of the bridge, BRIO stairs were enabled on each side of the arch and in two separate sections. The first section is 60 m high and rests on the ground. The second section, 40 m high, consists of three independent staircases arranged on BMK consoles on the arch.
