Moldtech boosts construction in Cuba with precast technology for the Strategic Bridge

 

 

With solid international experience in the infrastructure sector, moldtech has developed a cutting-edge mold for the manufacture of AASHTO post-tensioned beamsThese beams are crucial in road projects due to their robust structural capacity, strength and flexibility to adapt to various board configurations, which translates into a significant optimization of assembly processes and a reduction in execution times.

 

The equipment supplied is meticulously designed to produce precast beams measuring 20 or 25 meters in length, capable of generating two different cross-sections. The main assembly consists of two sides, two shears, a bottom, and a bottom support, which, when assembled, form the final piece. Additionally, the package includes bottoms measuring 25 meters long by 0,65 meters wide, an electric vibration system, and the vibration carriage essential for the manufacturing process.

 

Moldtech highlights its extensive global experience in infrastructure projects, ranging from the construction of bridges and roads to viaducts. A clear example of its capacity is the mobile factory which they designed for the on-site production of structural elements, maximizing efficiency and minimizing logistics costs in large-scale projects.

 

The company is distinguished by its high adaptability to meet the technical and engineering needs of each client. In the specific case of bridge girder molds, these are structured on a base—which can be a universal track, an existing concrete slab, or another type of bottom—and two "I"-shaped side molds with a quick fastening systemThis system allows the beam size to be adjusted in different positions, ensuring versatility.

 

The universal track provides a stable base, allowing for the pouring of various precast elements using configurable molds along its length. This structure is anchored to the ground, and the sides of the mold are assembled onto it using an adjustable system that allows the width to be varied using a single base plate.

 

The side moulds, which can incorporate manual or hydraulic opening, are fixed by means of a quick locking system both at the base and at the top, ensuring a optimal structural rigidity during the pouring and setting of concrete. They also feature a modular height-adjustable design, allowing for the manufacture of parts with various cross sections and the ability to adjust their length by adding shears.

 

This system is expandable, with the possibility of incorporating structural extensions, additional base plates, and modular molds, enabling the manufacture of different types of reinforced or prestressed elements. To ensure the superior quality of the final productThe molds integrate a pneumatic vibration system with independently acting VSP vibrators, a piping network, and a manifold for connection to the customer's compressor. A finned tube heating system can also be integrated, which accelerates concrete curing and increases productivity.

 

Among the complementary equipment available for this type of installation are hydraulic control units, tensioning lances, relaxation heads, prestressing anchoring systems, cable reels, masks, Giraffe-type vehicles for pouring, and concrete buckets.

 

This project in Cuba joins a list of international success stories where Moldtech has provided bespoke technical equipment in countries such as Colombia, Egypt, Mexico, Romania or Saudi Arabia. Previous customers have consistently praised the adaptability’s most emblematic landmarks, the ongoing technical support and end product quality from Moldtech as key factors in their decision.
