PRECAST CONCRETE ELEMENTS62 CPI %u2013 Concrete Plant International | India Edition %u2013 1 | 2026 www.cpi-worldwide.comThe system allows to produce prestressed I-beams ranging from 29.50 to 39.50 meters in length and 180 to 225 cm in height.The modular side forms, made of 6 mm thick steel plates and stiffened by structural frames, include both length and height adjustment systems, enabling maximum production versatility.All side moulds are equipped with vibration to improve concrete resistance and reduce air voids and finned curing pipes to optimize curing times addition finned pipes integrated under the casting base.Concrete distributionFour Bianchi Speedy concrete distribution machines each with a hopper capacity of 3 m%u00b3. The discharge of concrete takes place through a screw conveyor housed in a rotating arm protected with a hinged upper cover and an internal anti-abrasion plate. Lifting of the screw/hopper up to an angle of inclination equal to 16%u00b0 allows casting up to a height of about 3.500 mm. The fully enclosed drivers cab includes sound absorbing foam panels, an adjustable internal ventilation unit and a sliding window on the right side. The Speedy machines are powered by an ecological diesel engine, with low fuel consumption and noise characteristics. Hydraulic Equipment for Pre-Stressing, Relaxation Strands and Strand pusher.The supply also includes all the necessary prestressing equipment for pre-stressing of the strands: this included four hydraulic relaxation pump units for the operation of simple effect relaxation cylinders, four stressing hydraulic pump unit capable of operating alternatively two separate strand pre-stressing jacks incorporating a lifting structure for lifting and lowering of stressing jack, four 25-ton x 400 mm stroke single strand pre-stressing jack.
