Moldtech has recently built and commissioned four lines for the production of prestressed bridge girders for an important construction group in Slovakia.
Our client was awarded a contract for the production and installation of a substantial amount of bridge girders for an important road project, D4R7, consisting in a bypass motorway around Bratislava, also connecting the main radial expressways accessing the city.
We have been selected among the main precast equipment suppliers to design, build and commission four lines for prestressed I girders with different lengths, expanding and modernizing the client´s existing precast facilities.
All the equipment has been designed according to client’s requirements and specifications to allow manufacturing prestressed girders of different sections with each type of mould.
Each line consisted of a casting bed and baseplate with a fast locking system on top of which is assembled a flexible mould with modular height adjustment.
One of the four lines was equipped with a special mould with 48 m length and modular height up to 2,2 m with a hydraulic system to open and close the mould assembly with minimum effort and maximum production efficiency.
All the moulds feature a vibration System with electric vibrators and frequency converters to ensure an optimum concrete compaction.
At present moment, the lines are producing at maximum capacity with great efficiency to meet the project deadlines.
Moldtech continues consolidating its solid presence in Europe, supplying reliable tailor-made equipment in many countries.
