Moldtech installs mobile mega plant in Romania for road and bridge construction.
Moldtech supplied the following equipment:
– Four hydraulic bridge girder moulds, each with a length of 125 meters and adjustable height from 1 meter up to 2.4 meters and a total pre-stress force up to 1500 MT.
– Two fixed self-stressing tables of 2.4 x 30 meters and with pre-tress force up to 200 Tn.for the production of half slabs
– Two tilting tables of size 2.5 x 48 meters for the production of sound walls. The tables include a collapsible top shutter for easy release of the panels.
– Eight mechanical moulds for the production of parapets. The length of each mould is 12.5 meters and the parapet design complies with the Romanian road safety regulation.
– Eight mechanic moulds to produce diaphragms, with an adjustable height from 600mm up to 2200mm.
– The supply furthermore included one of the well-known MT20 dry cast box culvert machines which Moldtech has been selling since more than 10 years. This dry cast machine makes it possible to produce 10 box culverts in one shift thanks to its vibro-pressing system.
– For a swift process of filling the moulds Moldtech supplied several Giraffe concrete transport and distribution vehicles with a capacity of 4m3 and which can pour directly into the different moulds including the 2.2 meters high girder mould.
Despite the weather conditions associated to Romanian winter, it was decided that the equipment would be placed out in the open air so all the moulds had to be prepared for this challenge. Moldtech therefore designed a special containerized boiler system which design includes a 2×800 kW per hour water heater capable of delivering hot water to the casting beds which were equipped with a closed circuit of finned hot water pipes.
The supply also included other accessories such as tension jacks, strand pushing machine, hydraulic tension and de-tensioning units etc..
